Question 1

What is an SEO Checker and what does it analyze?

Accepted Answer

An SEO Checker evaluates fundamental on-page ranking signals on a single webpage. It inspects title tag length and pixel boundaries, meta description presence, H1-H6 heading hierarchy, canonical URL tags, Open Graph cards, image alt attributes, and structured data.

Question 2

Why does the tool offer both URL and HTML Source mode?

Accepted Answer

Modern web browsers enforce Same-Origin Policies and CORS restrictions that prevent client-side JavaScript from fetching arbitrary third-party websites directly. URL Mode uses existing safe server-assisted endpoints, while HTML Source Mode lets you paste code for 100% genuine, unrestricted client-side DOM parsing.

Question 3

What is the difference between character length and pixel width for titles?

Accepted Answer

Google desktop search results render page titles in an approximately 580px container (about 600px on mobile). Wide capital letters (like 'W' or 'M') take significantly more physical space than narrow letters (like 'l' or 'i'). A title with only 55 characters can still be truncated if it contains many wide characters.

Question 4

How do I perform a complete multi-page site crawl?

Accepted Answer

Single-page SEO checkers inspect one document at a time. The full RankingsFactor platform continuously crawls your entire domain, auditing internal link architecture, orphan pages, crawl depth, 404 broken links, and site-wide duplicate content.
