SEO audit tool for SaaS companies
Technical depth, content cluster hygiene, and why your marketing site's JS framework is hurting you

SaaS SEO fails in predictable ways: marketing sites built in React with no server-side rendering, docs treated as an afterthought, and landing page titles that describe the product instead of the search query. A page audit catches the render and on-page pieces — the cluster strategy is still your job.
Where saas companies SEO actually breaks
1. Your marketing site is a JavaScript app and Google sees nothing
If your landing pages are built with Next.js, Nuxt, or Gatsby without server-side rendering or static generation, Google gets a blank HTML shell. Yes, Googlebot executes JS now. No, it doesn't execute it reliably at scale. The audit checks for server-rendered content — if your page source is empty and your content hydrates client-side, you're invisible for 30-60% of queries depending on complexity.
2. Docs and blog live on a subdomain and you split your authority
support.company.com/docs and blog.company.com are two different sites to Google. Your domain authority splits across three subdomains instead of concentrating on one. Most modern SaaS SEO playbooks move docs and blog to /docs and /blog subdirectories for this reason. The audit can't fix the architecture, but it will flag missing canonicals when the same content appears on both.
3. Your feature pages are titled 'Team Collaboration' instead of 'project management software for remote teams'
SaaS marketing teams title pages after product features. Google ranks pages for search queries. These are different things. 'Team Collaboration' gets 2,400 searches/month. 'project management software for remote teams' gets 18,100. The audit will flag thin or generic title tags. The fix is a content strategy conversation, not a tooling one — but the audit is how you start it.
Which of the 12 audit checks matter most
AuditWidget runs 12 on-page checks. These five matter most for saas companies:
Title tag
Feature-based titles vs. query-based titles is the single biggest missed opportunity in SaaS marketing. Audit shows the current title verbatim.
Meta description
SaaS meta descriptions are usually brand copy ('The leading platform for...') instead of benefit + CTA. Audit flags missing and duplicate descriptions.
Structured Data (Schema)
SoftwareApplication + Organization schema is underused. FAQ schema on pricing and feature pages unlocks rich results competitors aren't claiming.
Page Speed
JavaScript bundle size is the #1 speed problem. Unused code, third-party scripts, and hydration overhead compound.
Canonical URL
Marketing and blog subdomains duplicating content. Campaign landing pages with UTM parameters creating duplicate URLs.
What an on-page audit can't check
A page audit can't check whether your site is server-rendered vs. client-rendered in a reliable way across all frameworks, can't validate your content cluster strategy, won't tell you if your topical authority is thin for the keywords you want to win, and can't see subdomain splits unless you audit each one separately. It also can't check docs search health, which is increasingly important as 'docs search' overtakes Google for developer traffic on established products.
How agencies in this space use the audit
SaaS SEO agencies run the audit on a prospect's highest-traffic landing page during the first discovery call. Screen-share the results. 'Here's what's fixable in the next sprint, here's what needs a quarter of content work.' It separates the $5K/mo retainers from the $500/mo 'just fix my title tags' work, and makes the pricing conversation concrete.
Questions people ask
Can Google index a SaaS marketing site built in React?
Yes, but with caveats. Googlebot executes JavaScript, but rendering is queued and can take days. For critical pages, use server-side rendering (Next.js with SSR) or static generation (Next.js with SSG, Gatsby, Astro). Check any key page by viewing page source — if the content isn't there, Google is guessing.
Should my docs live on a subdomain or a subdirectory?
Subdirectory, almost every time. /docs concentrates your domain authority. docs.example.com splits it. Exception: if your docs are maintained separately and you have real technical reasons to keep them split, then accept the SEO cost. For most SaaS companies, the cost is real — 20-40% less ranking potential for doc queries.
What SaaS-specific schema should I add?
SoftwareApplication schema on your homepage and product pages, Organization schema in the footer, FAQPage schema on pricing and feature pages. Review schema if you have real reviews from G2 or Capterra you can display. All of it is in the audit; most competitors skip it.
Why do my feature pages not rank?
Usually the title tag describes the feature, not the query. 'Team Collaboration' doesn't match how people search. 'Project management software for remote teams' does. Audit the title and H1 — if they match your internal product language instead of the search behavior, rewrite them.
