Frequently Asked Questions

What does this SEO content checker actually test?

It checks 7 real on-page fundamentals: title tag length, meta description length, a single H1 tag, presence of H2 subheadings, word count, a canonical tag, and image alt text coverage.

Does word count matter for SEO rankings?

It matters to the extent that comprehensive content tends to rank better for competitive queries. But 2,000 words of filler loses to a precise 500-word answer. Prioritize fully answering the query over hitting a word count.

What is thin content and why does Google penalize it?

Thin content is pages with little original value: auto-generated text, near-duplicate content, or pages that don't adequately address the search query. Google's Helpful Content System is built specifically to downrank it.

Why does my meta description length matter?

A meta description between 70 and 160 characters displays fully in Google's search results without being cut off, giving searchers a complete reason to click your result over a competitor's.

My page passes all 7 checks but still isn't ranking, why?

These are on-page fundamentals, necessary but not sufficient. Rankings also depend on backlinks, site authority, search intent match, and competition. Pair this checker with real performance data from Google Search Console.
