21 questions on on-page seo, each with an explanation. Free, no signup.
On-page SEO is everything you control inside a single page: the title tag and meta description, the heading structure, the words in your links, and whether the page actually answers the search it is meant to rank for.
The questions here cover the recommended lengths and counts (how long a title tag should be, how many H1s a page needs), the concepts that decide rankings (search intent, topic clusters, pillar pages, E-E-A-T) and the search features a well-built page can win (featured snippets, People Also Ask, knowledge panels).
This track has 21 questions. Learning mode asks 10 at a time with the explanation after every answer; the timed challenge asks 20 in 100 seconds. Free, no signup, and a different draw every time you retake it.
