Website Tracking Tools
The Website Tracking Tools category contains seven free tools for diagnosing and monitoring the technical health of any website. Each tool addresses a specific technical layer: link authority and broken links, server performance and compression, HTTPS security, search engine crawlability and indexing, and browser environment detection. Every tool runs in the browser — no installation, no account required for basic use.
The tools in this category are used primarily by SEO practitioners, web developers, site owners, and technical support teams for routine health checks, post-deployment verification, and diagnosis of specific performance or visibility problems. The directory below covers all seven tools grouped by function, with links and descriptions of what each one does and when to use it.
Note on the category name: 'Website Tracking Tools' here refers to technical monitoring and diagnostic tools — checking SSL certificates, verifying compression, finding broken links, simulating crawlers, and inspecting indexing status. These are not web analytics or visitor tracking tools. If you are looking for visitor behavior analytics (sessions, pageviews, conversion tracking), those require a separate analytics platform such as Google Analytics or Plausible.

Includes a user agent anatomy guide and rendering engine reference. | Reporting browser details to support teams, cross-browser QA testing, diagnosing environment-specific website issues, verifying language settings for localization problems. |
How the tools work together — four diagnostic workflows
Technical website health is not assessed by one metric. The tools in this category are most valuable when combined into workflows that address a specific goal. The four workflows below cover the most common diagnostic scenarios.
Workflow 1 — New site or post-launch check (15 minutes)
Run this workflow whenever a new site goes live or a major redesign is deployed:
| Step | Tool | Action |
| 1 | SSL Checker | Confirm the SSL certificate is valid, trusted, and covers both the bare domain and www version. Verify the expiry date is at least several months away. |
| 2 | Check GZIP Compression | Confirm the server is compressing HTML, CSS, and JavaScript. Uncompressed resources are a common deployment oversight. |
| 3 | Spider Simulator | Check the homepage and key landing pages through the crawler view. Confirm title tag, H1, meta description, and body text are in the static HTML — not injected by JavaScript. |
| 4 | Google Cache Checker | After a few days, verify key pages have been indexed. New sites typically take 1–2 weeks for initial indexation after sitemap submission. |
| 5 | Broken Link Checker | Scan the homepage and main category pages for broken links. Post-launch is the most common time for broken internal links from the old site structure to be discovered. |
Workflow 2 — Post-migration technical audit
Use this after any CMS migration, URL restructure, domain change, or hosting provider switch:
| Step | Tool | Action |
| 1 | SSL Checker | Verify the SSL certificate was correctly transferred or reissued on the new host. CDN or proxy SSL settings frequently change during migrations. |
| 2 | Broken Link Checker | Scan all key pages for broken internal links. URL structure changes during migrations create large numbers of 404s if redirect mapping was incomplete. |
| 3 | Check GZIP Compression | Confirm the new host or CDN configuration has compression enabled. Compression settings do not always transfer between hosts automatically. |
| 4 | Spider Simulator | Check that content and links still appear correctly in the crawler view after the migration. Template or CMS changes can cause content to shift from static HTML to JavaScript-rendered. |
| 5 | Google Cache Checker | Monitor indexing status of migrated pages. Pages that had strong rankings should be indexed within days of migration if 301 redirects are in place. |
| 6 | MozRank Checker | Check MozRank on key pages a few weeks post-migration to confirm that link equity is flowing correctly to the new URLs via the 301 redirects. |
Workflow 3 — Routine technical SEO health check (monthly)
A quick monthly check across your most important pages:
| Step | Tool | Action |
| 1 | SSL Checker | Verify certificate expiry date. Renew at least 30 days before expiry. Check both bare domain and www if not using a wildcard certificate. |
| 2 | Broken Link Checker | Scan homepage, main category pages, and any pages updated during the month. Catch broken links before they accumulate. |
| 3 | Check GZIP Compression | Quick confirmation that compression remains active. Server updates and CDN configuration changes can disable compression without warning. |
| 4 | Spider Simulator | Spot-check any page that received significant content updates. Confirm changes are visible in the crawler view, not just in the browser. |
Workflow 4 — Diagnosing a sudden ranking drop
When a page or set of pages loses rankings unexpectedly, run these checks in order:
| Step | Tool | Action |
| 1 | Google Cache Checker | Confirm the page is still indexed. A noindex tag or robots.txt change can de-index a page and cause an immediate ranking drop. |
| 2 | Spider Simulator | Check whether the page's content, title, H1, and links are still visible to crawlers. A CMS update or page builder change may have moved content behind JavaScript. |
| 3 | SSL Checker | Verify the certificate is still valid. An expired certificate triggers browser warnings that dramatically reduce traffic and can affect indexing. |
| 4 | Broken Link Checker | Check for broken internal links to the affected page. A page that receives no internal links may drop in rankings as it loses internal link equity. |
| 5 | MozRank Checker | Check the page's MozRank score. A significant drop in external backlinks (domain expiry, site removal) will show in a reduced MozRank score. |
Who uses these tools
SEO practitioners
MozRank Checker and the Broken Link Checker are the most frequently used tools for SEO work. MozRank provides page-level link authority benchmarks for competitive analysis and link-building prioritization. The Broken Link Checker identifies link equity leaks and crawl dead-ends that reduce a site's technical SEO health. The Spider Simulator is used in technical audits to confirm that on-page SEO elements — title tags, H1s, body text, internal links — are present in the static HTML rather than JavaScript-rendered. The Google Cache Checker monitors indexing status after content updates and migrations.
Web developers and site owners
The SSL Checker and Check GZIP Compression are the most useful tools for server-level technical work. SSL certificate monitoring prevents the most damaging avoidable site incident — an expired certificate that triggers browser security warnings and prevents users from accessing the site. GZIP compression verification confirms that the server or CDN is delivering compressed resources, which is a standard performance baseline for all production websites. Both tools are also used immediately after deployment or infrastructure changes to confirm settings transferred correctly.
Technical support teams
What Is My Browser is the primary tool for support teams diagnosing user-reported website problems. When a user says 'the page looks wrong' or 'a feature does not work', the first diagnostic question is always: what browser, version, and operating system are they using? The tool lets any user — including non-technical users — instantly retrieve and share this information. The Broken Link Checker is also used to investigate and resolve user-reported dead links or navigation failures.
QA engineers
What Is My Browser and the Spider Simulator are the most relevant tools for quality assurance work. QA engineers use browser detection to confirm the exact environment of a test device before logging a test result. The Spider Simulator provides a crawler's view of the page, which is used to verify that content and links are correctly structured in the HTML source before deployment. The SSL Checker is used to verify certificate coverage during staging and pre-production environments.

Frequently asked questions
What do the Website Tracking Tools in this category actually do?
These tools diagnose and monitor the technical health of websites — checking SSL certificate validity and expiry, verifying server compression, finding broken links and 404 errors, simulating how search engine crawlers read page content, checking Google indexing status, evaluating page-level link authority (MozRank), and detecting browser and device environment details. They are technical SEO and site health tools, not visitor analytics or traffic tracking tools. Each tool targets a specific technical layer and can be used independently or combined into diagnostic workflows.
What is the most important tool to check first for a new website?
The SSL Checker should be checked first for any new or recently migrated website. An invalid, expired, or misconfigured SSL certificate causes hard browser security warnings that prevent users from accessing the site. No other technical issue has a more immediate impact on both user access and search engine crawlability. Once SSL is confirmed, check GZIP compression (a quick performance baseline), then use the Spider Simulator to confirm that key pages are correctly structured for crawlers.
How often should I run these checks?
For most websites, a monthly check across key pages is a reliable baseline: SSL certificate expiry check, broken link scan on main pages, and GZIP compression verification. After any significant site change — CMS migration, URL restructure, domain change, CDN configuration update, hosting provider switch, or major content rebuild — run the full workflow immediately after the change. The Spider Simulator and Google Cache Checker are most useful after content or template changes that might affect crawler visibility.
What is the difference between the Spider Simulator and the Google Cache Checker?
The Spider Simulator shows what a search engine crawler sees in the raw HTML of a page right now — the content, links, and tags present in the static HTML before any JavaScript executes. It is a diagnostic tool for the page's current crawlable structure. The Google Cache Checker shows whether Google has indexed a specific URL and when it was last crawled — it answers 'does Google know this page exists?' rather than 'what does Google see when it visits?'. Use the Spider Simulator to check content structure; use the Google Cache Checker to verify indexing status.
Do broken links directly hurt my search rankings?
Google has stated that 404 errors are a normal part of the web and do not directly penalize rankings. The indirect effects are the problem: broken internal links interrupt the flow of link equity between pages, waste crawl budget on dead ends, and can leave pages undiscovered if the only crawl paths to them are broken. Broken links to pages that have valuable external backlinks are the highest-priority fix — a 301 redirect to a relevant live page immediately recaptures the link equity that was being lost. User experience damage from broken links is also an indirect ranking signal.
Why does GZIP compression matter for SEO?
GZIP compression reduces the size of text-based resources — HTML, CSS, JavaScript, JSON — by 60 to 80 percent before they are sent from the server to the browser. This directly improves page load time, which is a confirmed Google ranking signal and a component of Core Web Vitals (specifically, it improves Largest Contentful Paint and Time to First Byte). Google's PageSpeed Insights flags missing compression as a high-priority recommendation. Enabling GZIP is typically a single server configuration change and is one of the highest-return, lowest-effort technical performance improvements available.
What is MozRank and how is it different from Domain Authority?
MozRank measures the link popularity of a specific page URL on a 0 to 10 logarithmic scale — how many external pages link to that URL and how authoritative those linking pages are. Domain Authority measures the ranking potential of the entire domain on a 1 to 100 scale, aggregating signals from all pages across the site. MozRank is page-level; Domain Authority is domain-level. Use MozRank to evaluate how well-linked a specific page is. Use Domain Authority when you want to assess the overall competitive strength of a domain for outreach, link-building, or SERP analysis.
