Frequently asked
What does the SEO checker audit?
On-page fundamentals: title and meta-description length, a single H1, canonical URL, indexability, mobile viewport, HTML lang, Open Graph and Twitter cards, JSON-LD structured data, HTTPS, image alt coverage, content depth, and whether sitemap.xml is reachable.
Is this a full crawl of my site?
No - it audits the single URL you enter. For a multi-page security and speed audit, run a full SimplyScan scan.
