MarTech Stack.
Learn what MarTech Stack means in modern search and SEO.
The collection of marketing technology tools and platforms a company uses to execute, measure, and optimise its marketing programmes.
A MarTech stack is the integrated collection of marketing technology platforms — CRM, marketing automation, analytics, advertising, CMS, CDP, and SEO tools — that a marketing team uses to plan, execute, measure, and optimise marketing programmes. The term 'stack' reflects how these tools layer together, with data flowing between them to enable coordinated marketing execution.
The MarTech Landscape
The annual ChiefMartec MarTech Landscape report catalogues over 11,000 marketing technology solutions across categories including advertising, social, content, data, management, and commerce. Managing tool selection, integration, and cost across this landscape is a full-time responsibility at enterprise organisations, typically owned by the VP of Marketing Operations or CTO.
Core MarTech Stack Categories
Foundational tools: CRM (Salesforce, HubSpot, Pipedrive), Marketing Automation (HubSpot, Marketo, ActiveCampaign, Klaviyo), Analytics (GA4, Amplitude, Heap), Advertising (Google Ads, Meta Ads), CMS (WordPress, Contentful, Webflow), SEO (Semrush, Ahrefs, Aergos), CDP (Segment, Rudderstack, Twilio), and Email (Mailchimp, Campaign Monitor, Iterable).
Stack Rationalisation
MarTech sprawl — accumulating tools without intentional integration — is a common enterprise problem. Tools that duplicate function, don't share data, or are used by fewer than 50% of intended users waste budget and fragment data. Annual MarTech audits identifying: tools vs. requirements mapping, integration health, actual usage rates, and ROI attribution help rationalise the stack to the minimum viable toolkit.
