Serpkin
Rank higher on Google without learning SEO. Your coding agent does the work.
Serpkin finds what holds your website back, hands the fix to your coding agent to implement, and measures the ranking and click improvements in Google.
Overview
The Serpkin homepage
Serpkin is an SEO platform that works with coding agents like Claude Code, Codex and Cursor. It scans your website to identify the most valuable SEO fixes, provides detailed missions with file locations and step-by-step instructions for your agent to implement, and then verifies the changes worked on your live site. The platform measures the impact at 14 and 28 days against similar pages you didn't change.
Instead of generic audit lists, Serpkin ranks fixes by the traffic they can bring and hands your agent one clear task at a time. Your agent makes the change in your repository, you review and deploy it, and Serpkin shows whether it landed and what happened in Google. It connects to Search Console for real ranking data and tracks daily rank movements to surface new missions as opportunities appear.

Buyer questions
What is a mission?
A mission is one SEO task picked by Serpkin as the most valuable fix for your site. It includes why it matters, which pages to change with source files, step-by-step instructions for your coding agent, and checks that prove it's done. You review the change, and Serpkin verifies it and measures the result.
What does Serpkin add to my coding agent?
Your agent can already edit code. Serpkin tells it what to change and why: the next best SEO mission for your site based on real search data, with the files to touch, a recipe and checks. Then it shows whether the change landed and what happened.
Do I need Search Console? What about a brand-new site?
You can start without it, but connect it as soon as you can. A new site starts with foundation missions from the site scan like pages Google can't index and missing sitemaps. Third-party search data usually knows nothing about a new domain, so Search Console is where the searches you already appear in come from. Without it, growth missions come from keyword research and results are measured with rank checks.
What happens when there's nothing left to fix?
You're caught up, not done. Serpkin keeps checking your rankings and Search Console every day and your competitors every week, rescans your site and researches new topics every month. A new mission shows up as soon as one is worth your time.
What are credits?
Credits cover manual and automatic research: keywords, SERPs, competitors, AI visibility checks, content briefs, ranking estimates and backlink refreshes. A keyword research run uses 2 credits, initial ranking estimate uses 3. Monthly automatic research on paid plans uses at most about 14 credits and can be turned off in Settings.
