Which one is for you
Pick SEO Pro Extension if
- Fits if you size up a prospect's site in a few clicks during an audit
- Works for checking whether a backlink on a page is followed
Look elsewhere if
- Not for you if you want keyword, ranking or backlink data, as it has none
- Watch out: Core Web Vitals are mobile field data only, and pages without enough Chrome data show site-wide figures or nothing
- Too light for whole-site audits, since it checks one page at a time
- Skip it if you browse in Safari or Edge, as only Chrome and Firefox are listed
- Watch out: the store shows the last update as November 20, 2024, and the developer hasn't identified itself as a trader, so EU consumer rights don't apply
Pick Sprout SEO if
- Fits if you run quick on-page checks on client pages and want them in one panel
- Works for exporting a page's headings and copy for a content brief
Look elsewhere if
- Skip it if you want rankings or backlinks, as it links out to Ahrefs and Semrush for those
- Too light for whole-site audits, since it checks one page at a time
- Not for you if you browse in Safari, as only Chrome, Firefox and Edge are named
- Tight if you're mapping a big migration, as the Wayback exporter stops at about 100,000 URLs
- Watch out: the developer hasn't identified itself as a trader, so EU consumer rights don't apply

How this page was made
- The verdict at the top follows a fixed rule. When both tools are in the same category and either is in our top three for it, the verdict follows that ranking: the higher-placed tool is our pick. The top three weigh who each tool suits as well as its grades, so a pick can go against the GPA. Otherwise the page does not pick one and says which grades higher: the higher GPA first; on a tie, the one with a free plan, then the one that starts cheaper in dollars a month, counted the same way for both; if they are still level, what the choice depends on.
- The grades are our own, from each tool’s review or report card. The GPA is their average.
- Prices, plans and platforms come from each tool’s listing. The table above says where each price was read and when.
- The differences and the answers to the questions are worked out from those listings.
