The July 2025 Definitive Guide to Building Backlinks

Picture this: you've done everything right. The site is fast, the content is solid, the on-page optimization is clean. And yet the rankings won't budge. You dig into the data and the answer stares back at you — your competitors have three times the referring domains you do. That's when the real work begins. This backlink building guide exists to walk you through that work in full — no fluff, no tactics that stopped working in 2015, and no vague advice about 'creating great content and hoping people link to it.' We're going to cover what makes a backlink actually worth earning, every legitimate tactic worth your time, the mistakes that will get you penalized, and a simple framework for deciding where to spend your energy first.

July is a good time to revisit your link strategy. The summer slowdown in many industries creates real opportunity — journalists have fewer pitches in their inboxes, resource page curators are more likely to respond, and competitors often go quiet. Use that window.

What Makes a Backlink Worth Earning

Not all backlinks are created equal. Most SEOs know this intellectually and then proceed to chase any link they can get. The result is a link profile full of low-authority directories, spammy blog comments, and paid placements that add noise but not signal. Let's get specific about what Google actually values.

Relevance is the starting point. A link from a website in your industry — or adjacent to it — carries far more weight than a link from a random high-DA site with no topical connection to what you do. A cybersecurity firm getting a link from a tech news publication matters. That same firm getting a link from a cooking blog does almost nothing. Google's systems have gotten very good at modeling topical authority, and link relevance feeds directly into that model.

Authority is the second factor. Domain authority metrics from Moz, Ahrefs' Domain Rating, or Semrush's Authority Score are all imperfect proxies for what Google actually measures, but they're useful filters. I wouldn't obsess over hitting a specific DR threshold, but I'd pay attention to whether a site is genuinely trusted by other real sites in its space.

Traffic on the linking page is a signal that often gets overlooked. A link from a page that actually gets visitors is more valuable than a link from a page buried so deep no one ever sees it. When you're evaluating a target, look at the organic traffic to the specific page — not just the domain level.

Anchor text influences how Google interprets the link. Exact-match anchors (your exact target keyword) are powerful but risky if overused. A natural link profile has a mix of branded anchors, generic anchors ('click here', 'this guide'), partial-match anchors, and bare URLs. If your anchor text distribution looks too engineered, that's a red flag in a manual review or algorithmic filter.

Placement matters too. A link in the body of an article that a human editor chose to include is worth dramatically more than a link in the footer, sidebar, or a list of sponsor logos. Editorial in-content links are the gold standard.

Finally, consider link freshness and velocity. Earning links at a steady, natural pace looks healthy. A sudden spike of dozens of links in a week followed by nothing looks manipulative. Consistency is the goal.

Link Types: What They Are and What They Do

Before you build a single link, you need to understand the taxonomy. Different link types carry different risk profiles, pass different amounts of value, and require different levels of effort to earn.

Dofollow vs. Nofollow vs. Sponsored vs. UGC

Dofollow links pass PageRank. They're the ones that directly affect your rankings. Every time someone links to your site without adding a rel attribute, the link is dofollow by default.

Nofollow links (rel='nofollow') were Google's original way of telling crawlers not to pass PageRank along a link. In 2019, Google updated its stance, treating nofollow as a 'hint' rather than a hard directive — meaning they may or may not follow and count nofollow links depending on context. According to Google's official nofollow documentation, the rel='sponsored' and rel='ugc' attributes were introduced at the same time to give webmasters more precision.

Sponsored links should be used whenever a link was paid for in any way — product reviews, sponsored posts, affiliate arrangements. Using dofollow on paid links violates Google's link spam policies.

UGC (User Generated Content) tags apply to links in forums, blog comments, and other community-driven content. They signal low editorial control.

The takeaway: target dofollow editorial links as your primary goal. Don't dismiss nofollow links entirely — a nofollow mention in a major publication drives real referral traffic and brand signals — but build your strategy around earning links that actually pass equity.

Editorial vs. Acquired Links

An editorial link is one a writer or editor chose to include because your content genuinely earned it. No outreach, no exchange, no payment. These are the most valuable and the hardest to get at scale. Your digital PR, data studies, and truly exceptional content are the engines that produce them.

Acquired links are ones you actively campaigned for — through outreach, guest posting, resource page submissions, or broken link replacement. Done right, they're completely legitimate. The difference is in the editorial judgment involved: if a human made a real decision to link to you because you offered something useful, the link has integrity.

Digital PR: Earning Links That Move the Needle

Digital PR is the highest-ceiling link building tactic available to most brands. When it works, a single campaign can earn dozens of high-authority editorial links from national publications, trade outlets, and niche news sites — the kind of links you simply cannot replicate through outreach alone.

The core idea is simple: create something genuinely newsworthy and pitch it to journalists who cover that beat. What makes something newsworthy in an SEO context? Original data, timely research, surprising findings, or a strong opinion on a trend that's already in the news cycle.

The Digital PR Playbook

Original surveys and data studies are the workhorse of digital PR link building. Survey your customers, scrape publicly available datasets, or commission a quick research study. Package the findings with a clear headline stat — 'X% of Americans do Y' performs well because it gives journalists a ready-made data point. The key is that the data has to be genuinely interesting, not just self-serving.

Reactive PR (newsjacking) moves faster. Watch industry news, and when a story breaks that you have expertise on, pitch your commentary immediately. Journalists working on deadline will often quote an expert source to add depth to their piece. The speed matters — a pitch 48 hours after a story has moved on does nothing.

Visualization and tools earn links passively over time. An interactive calculator, an embeddable chart, or a well-designed infographic gives other publishers a reason to reference your site. The bar for quality here has gone up significantly — something basic won't get picked up. But if you build something genuinely useful, it becomes a link magnet.

Pitch craft matters as much as the idea. Keep your email subject line to a single clear hook. Open with the one-sentence takeaway. Don't bury the story. And send from a real person's email — not a generic 'press@' address. I've seen strong campaign ideas die because the pitch read like a press release from 2005.

HARO and Journalist Outreach

HARO — Help a Reporter Out — was acquired by Cision and rebranded as Connectively, but the model is the same: journalists post source requests, you pitch your expertise, and if they use your quote, you earn a link back to your site. It's one of the most accessible link building tactics for small businesses and individual practitioners.

The reality is that most HARO pitches fail because they're generic. Journalists get hundreds of responses to a single query. If your pitch is three vague sentences about how you're a marketing expert, it's going in the trash. Here's what actually gets selected:

• Lead with a specific, quotable insight — not credentials
• Answer the question directly in the first sentence
• Keep it under 200 words unless detail is explicitly requested
• Include a one-line bio with your actual title and company name
• Match your response to the exact angle the journalist described

Beyond Connectively, journalists actively look for sources on Twitter/X (search 'journorequest' or '#PRrequest'), LinkedIn, and through direct outreach. Building real relationships with two or three journalists who cover your space is worth more than submitting to 50 HARO queries. Follow their work, respond when they ask questions publicly, and offer useful context without always asking for something in return.

The links you earn from journalist outreach are typically from major publications with strong domain authority. Even a single mention in a respected trade outlet can shift your authority metrics visibly. This is not a quick win — you'll pitch a lot before you land consistent placements — but the upside is real.

Resource Page Link Building

Resource pages are exactly what they sound like: curated lists of links that someone has assembled for their readers. 'Best tools for small business owners.' 'Recommended reading for new marketers.' 'Useful resources for freelance designers.' These pages exist across nearly every niche, and many of them are genuinely well-maintained by real organizations — universities, nonprofits, industry associations, and niche blogs.

The tactic is straightforward. Find resource pages in your niche. Identify ones where your content would genuinely fit. Send a short, polite pitch explaining what you've built and why it belongs on their list. You're not asking for a favor — you're offering value to their readers.

How to Find Resource Pages

Use search operators in Google to surface them quickly. Try queries like: [your topic] + 'useful resources', [your topic] + 'recommended links', [your topic] + inurl:resources, or [your topic] + 'further reading'. You'll turn up dozens of targets in most niches.

Evaluate each one before you pitch. Check that the page is still actively maintained (no broken links, reasonable last-updated date), that the other links on the page are legitimate, and that the domain itself has some authority. A resource page on a university (.edu) or industry association domain is worth significantly more effort than one on a random low-traffic blog.

When you pitch, be specific. Reference the page by name, mention the specific content of yours you're suggesting, and explain in one sentence why it adds something their current list doesn't have. Generically asking to be 'added to your resources page' converts poorly. Showing you've actually read their list and thought about the fit converts much better.

Broken Link Building

Broken link building is one of the most legitimate and genuinely useful link acquisition tactics in the playbook. The premise: find links on external sites that point to pages that no longer exist (404 errors), create or surface content that serves as a replacement, and pitch the site owner on updating the link to point to your working resource instead.

You're doing them a favor. A broken link is a bad user experience and, on an established site, often a small embarrassment. Most site owners appreciate being told about it — and if you have a quality replacement ready, the conversion rate on these pitches is higher than cold outreach.

The Process Step by Step

1. Use a tool like Ahrefs, Semrush, or Screaming Frog to identify broken outbound links on relevant sites in your niche
2. Export the list and filter for pages that had meaningful inbound links before going dead — these are the most valuable replacements
3. Check what the original page contained using the Wayback Machine at archive.org
4. Identify whether you already have content that covers that topic, or whether it's worth creating something new
5. Reach out to the linking site with a short, friendly note: point out the broken link, explain what it used to cover, and offer your page as a replacement
6. Follow up once — but only once

The biggest mistake people make with broken link building is pitching before the content is ready. Your replacement needs to be at least as good as what the original page offered. If you're pitching a thin 400-word post as a replacement for a detailed guide that used to exist, you won't get the link — and you shouldn't.

Scale this by running it against competitor backlink profiles in Ahrefs. If a domain was linking to a competitor's page that now 404s, they're already familiar with your topic area and likely willing to link to something relevant.

Guest Posting Done Right

Guest posting has a complicated reputation. For a while, it was abused so heavily — mass submissions to low-quality 'write for us' farms — that Google's Matt Cutts famously declared it dead as a link building tactic back in 2014. And yet, a decade later, strategic guest posting on genuinely relevant publications remains one of the most effective ways to build authority links.

The distinction is quality and intent. Are you writing a valuable piece of content for a real publication whose audience will benefit from it? Or are you churning out 700-word filler for a site that will publish anything as long as it includes a link? Google knows the difference and so does any editorial team worth pitching.

Choosing the Right Publications

Target publications you'd actually want to be associated with. Industry blogs, trade publications, respected newsletters with web presence, and niche media outlets are all fair game. The test is simple: would being published here impress your best client? If the answer is yes, it's probably worth the effort.

Check the site's link profile before you invest time in a pitch. Use Ahrefs or Semrush to verify they have real organic traffic, legitimate referring domains, and that their content isn't thin or spammy. Plenty of sites that look professional on the surface are essentially link farms — and getting published there can do more harm than good.

Pitching and Writing

Your pitch email should do three things: show you've read the site, propose a specific topic angle (not a vague subject area), and demonstrate that you can actually write. If you can point to a previous published piece, include it. Editors are busy — make it easy to say yes.

When you write the piece, make it genuinely good. The link in your author bio or within the content is secondary to the value of the article itself. Strong guest posts earn you direct traffic, brand recognition, and sometimes follow-up opportunities from the same publication. Thin posts that clearly exist only for the link do none of those things and often get rejected or have the link stripped.

Common Mistakes

And yes, these mistakes show up constantly — even at agencies that should know better.

• Pitching generic topics that the site has already covered five times
• Including exact-match keyword anchor text in the link back to your site — this triggers red flags in a manual review
• Publishing on sites with a 'Contributors' or 'Write for Us' page so wide-open that anyone gets in
• Using AI-generated content without meaningful human editing or original perspective
• Submitting the same piece (or a slightly spun version) to multiple sites
• Forgetting to actually promote the published piece — which would have helped it earn secondary links naturally
• Treating the author bio link as the only goal and producing content that reflects that

Link Schemes and Tactics to Avoid

I've watched sites recover from core updates and manual actions, and in nearly every case, the root cause was the same: someone cut a corner on link building. Whether it was a bulk link purchase, a private blog network, or an 'SEO company' that promised 50 links a month for $199, the pattern repeats. It's always cheaper to build links right the first time than to clean up a penalty.

Google's link spam policies are explicit about what constitutes a violation. Let's run through the main ones.

Paid Links Without Proper Attribution

Paying for dofollow links — whether directly through a link broker, through a sponsored post without a rel='sponsored' tag, or through 'editorial placement fees' dressed up as content marketing — violates Google's guidelines. The risk has increased as Google has gotten better at detecting unnatural link patterns and as manual review teams have expanded their coverage of link networks.

Private Blog Networks (PBNs)

PBNs are networks of sites built or acquired specifically to link to a money site. They've been a staple of black-hat SEO for years. They still work in some low-competition niches in the short term. They also get deindexed in batches when Google's quality teams go after them — taking your rankings with them. The risk-reward ratio is simply not there for any business that depends on long-term organic traffic.

Link Exchanges

Reciprocal linking at scale — 'I'll link to you if you link to me' — is explicitly called out in Google's spam policies. Occasional, genuine cross-links between related businesses are fine. A systematic exchange program is not. Three-way link schemes (A links to B, B links to C, C links to A) are also well understood by Google's systems at this point.

Automated Link Building

Mass blog comment submissions, forum profile spam, and automated directory submissions produce links that Google's systems discount almost immediately. Worse, a sudden spike of these links can trigger a manual review. These tactics have essentially zero positive impact and carry non-zero downside risk.

Anchor Text Over-Optimization

If 60% of your backlinks use the exact same keyword phrase as anchor text, that's an algorithmic signal that your link profile was engineered rather than earned. Vary your anchors deliberately. Track the distribution in Ahrefs or Semrush and correct course if it's getting too uniform.

The Backlink Prioritization Framework

Here's the honest problem with most backlink building guides: they list every tactic but never tell you what to do first. If you're a solo founder with ten hours a month for link building, you can't do everything. If you're an agency managing twenty clients, you need a system for allocating effort. This framework is designed to answer the question: given your situation, where should you actually start?

Score Your Opportunities on Three Axes

For every link building tactic or opportunity, score it on Impact (how much authority will this realistically pass?), Effort (how much time, skill, and outreach does this require?), and Risk (what's the downside if this goes wrong?). Use a simple 1-3 scale for each. High Impact + Low Effort + Low Risk = do it first.

The Tier System

Tier 1: Do These First (High Impact, Low-Medium Effort, Low Risk)

• Unlinked brand mentions — someone referenced you without linking. Find them in Ahrefs Alerts or Google Search. Email and ask for the link. Conversion rate is high because you're already known to them.
• Broken link building on competitor profiles — high relevance, you're providing genuine value, and the path to yes is clear.
• HARO / Connectively responses — low time investment per pitch, upside is significant publications, and the risk is essentially zero.

Tier 2: Build Into Your Ongoing Rhythm (High Impact, Higher Effort, Low Risk)

• Digital PR campaigns — takes planning and content investment, but the ceiling is the highest of any tactic.
• Strategic guest posting on genuinely relevant publications — time-consuming to pitch and write well, but builds real authority and relationships.
• Resource page outreach — requires building a list and sending personalized pitches, but conversion is steady if your content is genuinely useful.

Tier 3: Opportunistic, Not the Foundation (Medium Impact, Variable Effort)

• Competitor link replication — use Ahrefs to find sites linking to competitors but not to you. These are pre-qualified targets. Work through the list methodically.
• Podcast appearances and interviews — links from show notes and transcripts, plus brand exposure. Worth doing if you already do these for business development.
• Scholarship and .edu links — still work in some cases, but the effort-to-return ratio has declined as .edu gatekeepers got savvier about link schemes.

The 90-Day Starter Plan

If you're starting a link building program from scratch, here's the realistic first 90 days:

1. Month 1: Run a full backlink audit. Identify your current profile, your top competitors' profiles, and the gap. Find unlinked mentions. Fix any obviously toxic links with disavow if you have a manual action.
2. Month 2: Start Tier 1 work. Reach out on unlinked mentions. Set up HARO/Connectively alerts for your relevant categories and pitch every day for a month. Begin building your broken link target list.
3. Month 3: Move to Tier 2. Plan your first digital PR campaign around a piece of original data or research. Identify five guest posting targets and begin the pitch process. Start resource page outreach for your best piece of content.

Consistency beats intensity every time. Ten solid link building hours per month, month after month, will outperform a 60-hour sprint followed by nothing.

What Makes a Good Backlink

• Topically relevant to your industry or content
• From a domain with real authority and real traffic
• Placed editorially in the body of content — not footer or sidebar
• Dofollow (unless it's from a major publication where nofollow is still valuable for referrals)
• Anchor text is natural, varied, and not over-optimized

Tactic Quick Reference

• Digital PR: Highest ceiling, requires original data or strong angles, pitches to journalists
• HARO/Connectively: Low effort, high upside, answer questions with specific quotable insight
• Resource pages: Find with search operators, pitch with a specific fit, works in most niches
• Broken link building: Use Ahrefs or Screaming Frog, replace dead pages, do the site owner a favor
• Guest posting: Target real publications, write genuinely good content, vary your anchor text
• Unlinked mentions: Easiest win, find with Ahrefs Alerts, email and ask for the link

Never Do These

• Buy dofollow links from brokers or link farms
• Participate in private blog networks
• Run large-scale reciprocal or three-way link exchanges
• Use automated tools to blast comment or forum links
• Over-optimize anchor text toward exact-match keywords
• Publish AI-generated guest posts with no original perspective or editing

Tools Worth Using

• Ahrefs — backlink analysis, broken link prospecting, unlinked mentions, competitor gap analysis
• Semrush — link audits, Authority Score tracking, backlink analytics
• Screaming Frog — crawling target sites for broken outbound links
• Connectively (formerly HARO) — journalist source requests
• Wayback Machine (archive.org) — see what broken pages used to contain
• Google Search Console — monitor your own link profile and spot anomalies

Where to Start

You now have a complete picture of link building in 2025. The strategy is clear. What separates the sites that build authority over time from the ones that spin their wheels isn't access to secret tactics — it's consistency and sequencing.

Here's your immediate action list:

1. Pull your current backlink profile in Ahrefs or Semrush today. Compare your referring domain count to your top three competitors. That gap is your target.
2. Set up a Google Alert and an Ahrefs Alert for your brand name. Every unlinked mention is a warm outreach opportunity waiting to happen.
3. Sign up for Connectively and set up daily alerts for two or three categories relevant to your industry. Commit to pitching every query that fits for 30 days straight.
4. Identify your strongest single piece of content — the one a resource page curator would actually want to link to. That's your outreach asset for resource page and broken link campaigns.
5. Block one hour per week on your calendar for link building. Just one hour. That's enough to send five solid pitches. Over a year, that's 250 touchpoints.

Link building is not glamorous and it is not fast. But it's the lever that makes everything else you do in SEO work harder. Clean up the site, write the content, earn the links. That's the sequence. July is a great time to start.
