Seylio vs Semrush
A focused Semrush alternative for teams that want work, not more reports.
Semrush is a broad marketing suite with one of the largest keyword and backlink databases. Seylio is narrower on purpose: one weekly audit across SEO, local and AI search, turned into a prioritised list that is verified after you act.
The short answer
Semrush
Choose Semrush when you need very large-scale keyword and backlink research across many countries, or marketing tools beyond SEO such as advertising, social media and content marketing suites.
Seylio
Choose Seylio when you manage your own or your clients' sites and want one routine that says what to fix first, uses your own Google data, includes AI search visibility and checks whether the fix worked.

Where Semrush is stronger
Semrush has built a very large proprietary keyword and backlink index over many years. For deep competitive research across many markets, or for advertising, social and content marketing in the same subscription, it offers more than Seylio does.
Where Seylio is different
Seylio starts from your own Google data and a weekly crawl of your site, and turns everything it finds into one prioritised list. Each action carries the affected URLs, evidence and acceptance criteria, and the next audit confirms whether it is solved.
AI search visibility in ChatGPT, Perplexity and Google AI Overviews is part of the same audit and the same list, not a separate product. And every plan contains every feature, so the price only grows with the size of your work.
Good to know.
Can Seylio fully replace Semrush?
For many websites and agencies, Seylio covers the day-to-day SEO work: technical audits, search performance, keywords, backlinks, competitors, local and AI visibility. If you rely on very large international keyword or backlink research, or on Semrush's advertising and social tools, Semrush can remain a useful addition.
Does Seylio need a Semrush subscription?
No. Seylio uses your own Google data, its own crawler and external data providers.
Is Seylio's backlink data as big as Semrush's?
No, and Seylio does not claim it is. Its backlink and authority data comes from external providers and is labelled as an estimate.
