ReachKit vs Semrush
Semrush offers a free SEO Checker at semrush.com/siteaudit, powered by its Site Audit, and on raw coverage it checks more than ReachKit does. ReachKit's free scan looks at something else as well: the Google searches buyers in your market make, who is on the first page, and whether AI answers mention you. If you want the widest audit of what is wrong with a site, pick Semrush. If you want pages put live to win those searches, pick ReachKit.
Who does each job?
You do 3 of the 5 jobs, for every page.
You do none of them. You can still edit or stop any page.
What Semrush does well
The free SEO Checker returns an overall score, a prioritized to do list and a detailed report. It covers on-page elements, off-page signals such as backlinks and authority, technical SEO such as crawlability, indexing and canonicals, site performance including Core Web Vitals, and social media visibility. Semrush states you can run one check per day for free.
The paid path goes further. Site Audit checks hundreds of technical and on-page issues, and Semrush One advertises more than 140 technical and on-page checks. Semrush offers a seven day free trial, cancel any time.
For a large site, or a team with a marketer on it, that breadth is the right tool.
What ReachKit does instead
Every Monday we check what your buyers search and ask AI. Then up to 7 pages a week go live on your site by themselves.
Your part: about 10 minutes, once.
