SaaS SEO Checklist: 12 Fixes for Software Company Websites

A SaaS SEO checklist covers the parts of a software company's site that generic SEO advice misses: docs and app subdomains, JavaScript rendering, a crawlable pricing page, honest comparison pages, SoftwareApplication schema and a changelog that earns links. Get rendering, canonicals and internal links right first, then build pages around the questions buyers actually search.

SaaS sites tend to grow in layers. The marketing site runs on one CMS, the docs on another platform, the app on its own framework and the blog somewhere else again. Each layer is fine on its own. The SEO problems appear where they meet. This checklist works through those seams in the order we'd fix them.

The SaaS SEO checklist at a glance

1. Check how JavaScript renders

Google processes JavaScript sites in three phases: crawling, rendering and indexing. Its JavaScript SEO basics say pages with a 200 status go into a rendering queue, where a headless Chromium runs the scripts, and Google then indexes the rendered HTML. So client-rendered content can be indexed, but there are traps:

• Links must be real links. Google only discovers links that are <a> elements with an href. Buttons with click handlers aren't followed.
• Noindex can't be undone in JavaScript. If Google sees a noindex tag in the initial HTML, it may skip rendering, so removing it with a script may not work.
• Single-page apps often return 200 for missing pages. Google suggests redirecting to a URL that returns a real 404, or adding a noindex tag with JavaScript, to avoid soft 404s.

Google still calls server-side or pre-rendering "still a great idea", because not every bot runs JavaScript. That includes many AI crawlers. And it describes dynamic rendering, serving bots a different version, as "a workaround and not a recommended solution". For marketing and docs pages, use server-side rendering or static generation, then confirm with Search Console's URL Inspection tool that the rendered HTML contains your headings, copy and links.

2. Keep the app out of search, keep marketing in

Decide which hostnames and paths should be indexed. Typically:

• Index: marketing site, pricing, use-case pages, integrations, docs, blog, changelog.
• Keep out: app routes behind login, account and billing pages, staging and preview deployments, internal search results.

Logged-in pages are usually safe because Google can't see them, but staging sites and preview URLs leak all the time. Put them behind authentication rather than relying on robots.txt, which stops crawling but doesn't guarantee a URL won't be indexed. Our guide to noindex vs robots.txt disallow explains the difference. Use the robots.txt tester to check specific paths against your rules.

3. Docs, blog and app on subdomains

Google treats subdomains and subfolders as workable either way. Our article on subdomain vs subdirectory SEO covers the trade-offs. In practice, most of the problems on SaaS sites come from the connections between properties, not the choice itself:

• Internal links both ways. Docs should link to relevant product and pricing pages, and the marketing site should link into the docs, not only to a docs home page.
• Consistent canonicals. Every page needs a self-referencing canonical on its own hostname. A common mistake is a docs platform that canonicalises to a default hosted domain such as yourproduct.docsplatform.io. See our canonical tags guide.
• One brand, one navigation. A docs site with different branding and no link back to the main site looks like a different company to users and search engines alike.
• Redirects after migrations. When docs move from a subdomain into /docs or the other way round, map every old URL to its new one with a 301. The redirect checker catches chains and loops.

4. Sitemaps for every property

Each property should have its own XML sitemap listing only canonical, indexable URLs, and each should be submitted in its own Search Console property. Watch for sitemaps that include app routes, staging URLs, redirected pages or old docs versions. The sitemap checker flags URLs that don't return 200. Our XML sitemap guide covers the format.

5. Make the pricing page crawlable and honest

The pricing page is often one of the most visited pages on a SaaS site and one of the worst built for search. Common faults: prices loaded by a script after a toggle, plan names inside images, and no explanation of what each plan includes.

• Put plans, prices and feature lists in HTML text. A monthly/annual toggle is fine if both sets of prices are in the page source.
• Answer the objections in text: trial length, cancellation, VAT, user limits, what happens at overage.
• Add an FAQ section that covers billing questions people search for, such as "does X have a free plan".

If you sell to consumers as well as businesses, UK consumer law applies to how you show prices. The CMA's guidance on unfair commercial practices says showing a headline price and then adding mandatory charges later in the purchase, known as drip pricing, is prohibited under the Digital Markets, Competition and Consumers Act 2024. Mandatory fees belong in the headline price. The Act's separate subscription contracts rules aren't in force yet, so keep an eye on them if you run consumer subscriptions. Other countries have their own pricing and renewal rules (in the US, for example, many states have automatic-renewal laws), so check the rules wherever your customers are.

6. Comparison and alternative pages

"X vs Y" and "Y alternatives" searches come from buyers close to a decision, so comparison pages are worth building. A competitor SEO analysis shows which rivals you actually share search results with. They also carry legal risk, because claims on your own website count as marketing.

The ASA applies the CAP Code to claims on company websites, and its advice on comparisons with identifiable competitors is clear: comparisons must not mislead, must compare products meeting the same need, and must compare material, relevant, verifiable and representative features. The ASA's guidance on verifiability says readers must be able to check the comparison themselves. In practice:

• Date the comparison and update it when a competitor changes pricing or features.
• Link to the competitor's own pricing or feature page as the source for each claim.
• Avoid unqualified superlatives such as "the best" or "the cheapest" unless you can prove them.
• Be fair about where the competitor fits better. It makes the page more credible to buyers, too.

7. Use-case and integration pages

Build one page per genuine search intent: "invoicing software for contractors", "connect X to HubSpot", "X for agencies". Each needs specific content, such as screenshots, setup steps and limits, not a template with the industry name swapped in. Thin, near-duplicate pages created at scale are exactly what Google's spam policies on scaled content target, and they rarely rank anyway.

Integration pages are especially useful because they match how people search: "[your product] [other tool] integration". Include what syncs, in which direction, on which plans and how to set it up, then link to the matching docs page.

8. SoftwareApplication and Organization schema

Add Organization markup on the home page with your name, logo, URL and social profiles. On the main product page, use SoftwareApplication. Google's software app documentation lists the requirements for rich results:

• Required: name, offers.price (use 0 for a free app) and either aggregateRating or review.
• Recommended: applicationCategory, such as BusinessApplication or DeveloperApplication, and operatingSystem.
• For paid apps, add offers.priceCurrency, otherwise Google tries to work the currency out itself.

Ratings must reflect real reviews that users can see, in line with Google's review snippet guidelines. Build the markup with the free schema generator and test it with the schema markup validator. Our structured data guide explains the wider picture.

9. Docs SEO

Documentation often ranks for long-tail, high-intent queries such as error messages, API methods and "how to" questions. A few rules keep it searchable:

• Unique, descriptive titles. "Authentication | Docs" on twenty pages helps no one. Use "API authentication with OAuth 2.0 | Product Docs".
• Readable URLs that reflect the hierarchy, such as /docs/api/authentication.
• Versioning: if old versions must stay online, canonicalise them to the current version or keep them out of the index, so they don't compete.
• Code samples and headings in HTML, not screenshots.
• Search inside the docs shouldn't create indexable result pages.

Run the meta tag checker on a sample of docs pages to spot duplicated titles and missing descriptions.

10. A changelog that earns links

A public changelog shows the product is alive, gives sales and support something to link to, and attracts links from customers and review sites. Give each meaningful release its own dated entry or page with a clear heading, what changed, who it affects and a link to the relevant docs. Avoid an infinite-scroll page where entries have no URL of their own.

11. Decide your AI crawler policy

Buyers increasingly ask AI assistants which tools to use. Many SaaS companies allow AI search crawlers on marketing and docs pages, so they can be cited, while blocking app routes. Training crawlers are a separate decision. Our guide to blocking or allowing AI crawlers explains which bot does what, and the AI crawler checker shows what your current robots.txt allows.

12. Measure each section separately

Add a Search Console property for each hostname, or a Domain property that covers them all, and segment performance by section: marketing, docs, blog, changelog. That shows whether docs bring signups or just support traffic, and which comparison pages win clicks. Rerun a technical audit after each major deploy, because SaaS marketing sites change often.

The free tools on our tools for software and SaaS page cover most of the checks above. If you want to connect search data, signups and support questions into one workflow, Make It Flow works with software companies on that kind of automation.

FAQ

What is the most important item on a SaaS SEO checklist?

Rendering and crawlability come first. If your marketing pages, pricing and docs depend on client-side JavaScript that bots can't render, nothing else on the checklist matters. Use server-side or static rendering for public pages and confirm with URL Inspection that the rendered HTML contains your content and links.

Should SaaS docs be on a subdomain or a subfolder?

Either can work. Google handles both. Choose what your platform supports well, then make sure docs and the marketing site link to each other, use self-referencing canonicals on their own hostname, have their own sitemap and share consistent branding and navigation.

Do SaaS companies need SoftwareApplication schema?

It isn't required, but it helps search engines understand what the product is. For a software app rich result, Google requires a name, offers.price and either a review or an aggregateRating. Only mark up ratings that come from real reviews shown to users.

Are competitor comparison pages legal in the UK?

Yes, if they're fair. The ASA applies the CAP Code to claims on your own website. Comparisons must not mislead, must compare products meeting the same need, and must be based on verifiable features. Date the page, cite sources and update it when competitors change.

Should a SaaS pricing page show prices?

Showing prices in HTML text helps both buyers and search engines, and it lets the page rank for pricing queries. If you sell to consumers, include mandatory charges in the headline price, because the CMA treats drip pricing as prohibited under the DMCC Act 2024.

Does a changelog help SEO?

It can. Dated, linkable release entries give customers, partners and review sites something specific to link to, and they show the product is actively maintained. Give each significant release its own URL and link it to the matching docs page.
