SEO Pro Extension review: our take
SEO Pro Extension reads the page in front of it and nothing else: title, meta description, canonical, robots directives, word count, the HTTP status and redirect chain, and mobile Core Web Vitals (LCP, INP, CLS) from the Chrome UX Report. Separate tabs list headings, links with nofollow highlighted, images with their alt text, and schema types, and most of it exports to CSV.
It is free, with an optional donation, and runs in Chrome and Firefox. That makes it a quick way to check whether a backlink is dofollow or a competitor's page is noindexed. It reports no link metrics or traffic, and the store listing shows no update since November 2024. MozBar adds Domain Authority and Page Authority on a free Moz account, which this extension does not attempt.
What SEO Pro Extension does
For the page you are viewing, the extension shows title, meta description, canonical, meta robots, language and word count, and warns when a page is noindex or canonicalized elsewhere. It shows the HTTP status and redirect chain, checks http/https and www/non-www duplicates, and pulls mobile Core Web Vitals (LCP, INP, CLS) from the Chrome UX Report, falling back to origin data. Separate tabs list headings as a tree, internal and external links with anchors (with nofollow highlighting), images with alt text and dimensions, schema types and Open Graph previews; headings, links, images and page copy export to CSV or TXT.
