Which one is for you
Pick SEO Spider Tools if
- Fits if you check a page's redirects, directives and broken links while browsing
- Works for site owners who want an .htaccess file for redirects and caching without writing it
Look elsewhere if
- Too light for whole-site audits, which SpiderNow sells on its website from $6.99 a month
- Watch out: the listing doesn't say whether it needs a SpiderNow account or counts against that account's scans
- Skip it if you're on Firefox or Safari, as only Chrome and Edge versions are listed
- Watch out: the Chrome version was last updated in October 2023, and the developer isn't a declared trader, so EU consumer rights don't apply
Pick Website SEO Checker if
- Fits if you check a page's tags, indexing rules and hreflang without opening its source
- Works for Sitechecker users who want a page's Search Console clicks and queries beside it
Look elsewhere if
- Too light for whole-site audits, as it checks one page and site crawls are a separate Sitechecker product
- Tight if you won't make a Sitechecker account, since Search Console figures and monitoring need one
- Not for you if you browse in Firefox, Safari or Edge, as it's listed for Chrome only
- 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.
