Sound familiar?

SEO is broken for most people.
Here's what we fix.

01

โ€œYou ran a free SEO audit, got a list of 47 problems, and still don't know which one to fix first.โ€

DidYouSEO ranks every issue by impact - your first fix is always your highest-leverage one.

02

โ€œYour site's been live for months. ChatGPT still recommends your competitor when someone asks about your niche.โ€

AI Visibility tracking shows exactly whether ChatGPT, Gemini and Perplexity mention you - and what to change.

03

โ€œYou noticed traffic dropped last month. You don't know why, or when it actually started.โ€

Continuous monitoring alerts you the moment your SEO score changes, before it hits your traffic.

04

โ€œYou're paying for Ahrefs, Semrush, and two other tools - and still don't have a clear picture.โ€

One dashboard for audits, AI visibility, rank tracking and monitoring. No tab-switching.

05

โ€œYour competitor published four posts this week and outranks you on keywords you've never even heard of. You found out... never.โ€

Competitor tracking scans their sitemap daily and shows every keyword they rank #4-15 for - your easiest wins, sorted by search volume.
