SEO audits by industry › SaaS

Technical SEO audits for SaaS sites

SaaS marketing sites are deploy-velocity environments. The pricing page, feature pages, and docs ship multiple times a week, and any regression on the canonical, title, or render-blocking JS path costs trial signups before anyone notices. Wrendex runs the same catalog of checks on every deploy.

All 140+ checks run on every audit. Free audit, no credit card.

Issues that frequently surface on SaaS sites

6 common patterns from real audits.

Pricing page canonical drifts during A/B tests

Variant URLs for pricing experiments inherit a canonical pointing at the original variant, so the test page never gets indexed and the live page keeps every backlink.

Docs subdomain leaks into the marketing index

Mintlify or readme.io docs render at /docs or docs.example.com without a clear canonical strategy, producing duplicate-content overlap with the public marketing pages.

Render-blocking analytics on /pricing

Multiple analytics scripts and product-tour SDKs load synchronously above the fold, pushing TTFB on the highest-intent page past the threshold where bounce rate spikes.

Feature pages share a templated title

Every /features/<name> page renders the same <title> because the template did not interpolate the feature name. Search engines collapse them in the SERP.

Sitemap drifts from the routing config

New marketing pages get shipped without a sitemap entry; deprecated pages stay in the sitemap pointing at 404s. Both are common after framework upgrades.

JS-rendered hero never crawled

Hero copy and the primary CTA render client-side via React, but the bot crawl returns the loading state. The most important page on the site is invisible to search engines.

Wrendex catalog checks that fire on SaaS sites

9 checks, 5 linked. Linked checks open the full catalog entry: what it is, why it matters, how to fix it. The rest are industry-specific checks fired during the audit; their detail pages arrive in the next catalog refresh.

• title-missing
• title-duplicate
• canonical-missing
• canonical-points-to-4xx
• duplicate-tracker (detail page coming)
• multi-version-library (detail page coming)
• redirect-chain
• Render-blocking JS (detail page coming)
• Client-side-only content (detail page coming)

What an audit run on a SaaS site actually produces

5 steps on the first run.

1. Crawl every public marketing surface. Wrendex hits /, /pricing, /features, /docs, /blog, and every linked landing page at the live deploy URL.
2. Render with a real browser. Each page is also fetched with a headless Chromium so client-side-rendered content gets graded the way Google sees it.
3. Group issues by deploy unit. Findings cluster by template family so engineering can triage one PR per template, not one PR per URL.
4. Get PR-ready fix copy. Every finding ships with the exact head fragment, the exact status code, the exact JSON-LD to emit.
5. Re-crawl on the next deploy. Wrendex reads the sitemap last-modified dates and re-fetches only the pages that changed on the next audit.
