SEO Spider Tools review (2026): is it any good?
SpiderNow's free extension for technical and on-page SEO checks
SEO Spider Tools report card
Very good · out of 4.0 · graded Oct 23, 2026
Best for technical checks on one page, plus .htaccess files
SEO Spider Tools is SpiderNow's free extension for one page's indexing rules, links, redirects, status codes, speed, tags, hreflang and schema, with a text editor and an .htaccess builder on the side. Full-site scans are sold on SpiderNow's website from $6.99 a month, the listing doesn't say whether the extension needs an account, and it hasn't been updated since October 2023.
Who SEO Spider Tools is for
- 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
Who SEO Spider Tools is not for
- 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
Why SEO Spider Tools gets a 3.0
Five grades, each with its reason. The GPA is their average: an A is 4 points, an F is none.
- AValue for moneyFree from the Chrome Web Store, which lists no in-app purchases. SpiderNow's site scans are sold separately, from $6.99 a month.
- AFree plan and trialFree outright as far as the store shows: every check, the content editor and the .htaccess builder. The listing can't say whether it needs a SpiderNow account.
- CFeaturesRobots and meta directives, links with follow status, broken links and redirect chains, status codes, Core Web Vitals, titles, headings, canonical, hreflang, schema errors and thin pages. The gap the listing names: one page at a time, with full-site scans sold separately.
- BEase of useNo rating on record, and nothing to set up is on record: install it and open the panel on a page.
- CPlatforms and integrationsChrome and Edge, so computers only. It pulls Core Web Vitals from PageSpeed Insights, and nothing else is listed.

Keep SEO Spider Tools, or make your own?
Keep it
SEO Spider Tools is free, so making your own would save you nothing.
And it is not the kind of software a weekend replaces.
What you could make
- Schema markup and internal linking: an app builder makes these well.
What you could not
- A crawler that checks every page of a site.
- Speed tests run from real browsers on a schedule.
What this rests on. SEO Spider Tools’s listing: what it does, where it runs, what it plugs into and what it costs. It is a judgement about the kind of software this is. We have not built a replacement for it, and making your own means looking after it too. How we decide, and every tool’s verdict.
What is SEO Spider Tools?
SEO Spider Tools is the free Chrome extension from SpiderNow, a website crawler and audit service. It checks a page's indexing directives, links and redirects, status codes and speed, titles, descriptions, headings, canonical and hreflang tags and structured data, and flags thin content. It also has a text editor with live SEO alerts and generates .htaccess files for redirects and caching.

- Chrome and Edge versions are listed; the Chrome listing was last updated on October 11, 2023.
