Checkbot vs SEO Spider Tools (2026): which should you pick?

Pick Checkbot if

• Fits if you check a site of under 100 URLs for broken links and bad markup before launch
• Works for developers testing a staging or localhost site, on the paid plan

Look elsewhere if

• Tight if your site runs past 100 URLs, as the free plan stops there and shows ads
• Watch out: it doesn't run JavaScript, so content added by scripts isn't checked
• Watch out: CSV and PDF exports, localhost and password-protected crawls all need Professional
• Pricey if you pay month to month, at $15 against $10 billed yearly, and a plan covers one person
• Not for you if you're not on Chrome, as the FAQ says there's no other browser version

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

Checkbot

• It runs only in Google Chrome; the FAQ says there is no Firefox or other browser version.
• The free plan stops at 100 URLs per crawl and shows ads; localhost crawls and exports need Professional.
• It does not execute JavaScript while crawling, so content added by scripts is not tested.
• A subscription covers one person; new customers can get a full refund within 14 days.

SEO Spider Tools

• 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.

Checkbot

Site-wide crawl

Crawls hundreds of pages at once from a start URL and scores them against 50+ rules drawn from Google, Mozilla and W3C guidance.

SEO checks

Finds broken links, missing or long titles and descriptions, duplicate content, canonical problems, missing image alt text, temporary redirects and sitemap issues.

Speed and security checks

Flags redirect chains, unminified or render-blocking CSS and JavaScript and missing caching or compression, plus HTTPS, mixed content and security header gaps.

Staging and localhost sites

Crawling runs on your own machine, so the paid plan can test localhost, private-network and HTTP Auth password-protected sites.

Crawl filters and quick rechecks

Limit a crawl by subdomain, folder, depth, pattern or file type, and recrawl a single page to confirm a fix.

PDF reports and CSV export

The Professional plan exports problem lists to CSV in bulk and produces PDF summary reports for clients or teammates.

SEO Spider Tools

Indexing directives

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

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.

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.

Tags and structured data

Checks titles, descriptions and H1 to H6 headings for length and duplicates, canonical and hreflang tags, schema errors and pages under 250 words.

Content editor

Edit page text with alerts on title, description and heading limits, and counts of characters, words, sentences, repeated words and keyword density.

.htaccess generator

Builds an .htaccess file with 301 redirects, a www rewrite, caching rules for scripts and images, hotlink protection and custom error pages.
