Part 01 · Overview

Welcome

What it is, who it suits, its grades and the ten things to know first

3.0

GPA, above 17 of the 34 other SEO browser extensions we grade

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.

To get you started, here are 7 things to know about SEO Spider Tools, taken from its own pages and our grades.

No rating on record, and nothing to set up is on record: install it and open the panel on a page.
From our grade for ease of use
  1. 1

    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.

  2. 2

    It is free

    SEO Spider Tools has no paid plan at all. The extension is free to install; the store listing lists no in-app purchases. SpiderNow's own account plans are sold separately.

  3. 3

    Finds URLs blocked by robots.txt and pages set to noindex, nofollow, noarchive or nosnippet, and shows resources blocked from rendering.

  4. 4

    Links and redirects

    Lists inlinks and outlinks with anchor text and follow status, and finds broken links, redirect chains and loops, JavaScript redirects and meta refreshes.

  5. 5

    Status and speed

    Shows status codes, SSL, server type, response time, file sizes and load time, plus Core Web Vitals scores for mobile and desktop from PageSpeed Insights.

  6. 6

    A 3.0 GPA, above 17 of 34

    That is against the other SEO browser extensions we grade, on value, the free plan, features, ease of use and platforms.

  7. 7

    Keep it

The report card

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.

ToolGPA report cardSEO Spider ToolsGraded Oct 23, 2026
SubjectGradeComment
Value for moneyAFree from the Chrome Web Store, which lists no in-app purchases. SpiderNow's site scans are sold separately, from $6.99 a month.
Free plan and trialAFree 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.
FeaturesCRobots 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.
Ease of useBNo rating on record, and nothing to set up is on record: install it and open the panel on a page.
Platforms and integrationsCChrome and Edge, so computers only. It pulls Core Web Vitals from PageSpeed Insights, and nothing else is listed.
Grade point averageVery good, out of 4.03.0

An A is worth 4 points, a B 3, a C 2, a D 1 and an F nothing. The GPA is the average of the five.

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 it 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

Good to know

Good for

  • Technical checks of a page's links, redirects and directives while browsing
  • Site owners who want an .htaccess file without writing it by hand
  • Freelancers trying SpiderNow before paying for full-site scans

Worth knowing

  • Full-site scans and reports are sold on SpiderNow's website: a free account covers a few single-page scans a month, and paid plans start at $6.99 a month.
  • The listing does not say whether the extension needs a SpiderNow account or counts against its scan limits.
  • Chrome and Edge versions are listed; the Chrome listing was last updated on October 11, 2023.
  • The developer has not identified itself as a trader, so EU consumer rights do not apply, as the store listing notes.

Keep it, or make your own?

Whether this is something you could build for yourself with an AI app builder, and what you would give up.

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.
