Best AI tools for marketers

Marketing teams were among the first to use AI for writing, and the first to notice the limits of it. Generic copy is easy to produce and easy to ignore. The tools here go a step past drafting: they audit a site for search, check how it appears in AI answers, plan and schedule posts, and pull real data from analytics and ad accounts so the assistant is working from numbers instead of guesses.

Skills, servers and apps for marketing

Many entries are agent skills: packaged instructions that teach Claude or another assistant a method, such as an SEO audit, a landing page review or a content brief. They cost nothing to try and do not touch your accounts.

MCP servers and apps go further. They connect to a scheduler, a CRM, a search console or a scraping service, which makes them more useful and means you should read what access they ask for before you connect a company account.

Search now has two audiences

People still search Google, and more of them now ask ChatGPT, Perplexity or Google's AI answers instead. Several tools on this page check both: classic on-page SEO, and whether a page is easy for an AI system to quote. Plain structure, clear facts and pages that answer one question well help with both.

The tradeoff: tools that write content at scale make it easy to publish pages nobody needs. Search engines treat thin, repeated pages as spam, so use the writing tools to improve a few pages, not to multiply them.

Questions

Can Claude do SEO?

With the right skill or server, it can run a structured audit, draft briefs, write schema markup and read your search data. It still needs a person to decide what to publish and to check facts.

What is GEO?

Generative engine optimisation: making pages easy for AI search tools to find, trust and quote. Several marketing skills in this list cover it next to classic SEO.
