A website that worked fine at launch often starts showing SEO problems as a business grows — more pages get added without a plan, old content is never revisited, and technical issues accumulate quietly. This checklist is written for that stage: not a brand-new site, and not an enterprise one, but a growing business site that needs a structured health check.
Work through it in order — technical health first, then on-page fundamentals, then content quality — because problems earlier in the list tend to undermine fixes made later.
This checklist is also organised around two moments that matter most: the pre-launch review before a new page, section or redesign goes live, and the post-launch review that confirms it is actually behaving as intended once real traffic and crawlers hit it. Treating both as distinct steps — rather than assuming a page is fine simply because it looks fine in a browser — catches a surprising number of avoidable issues.
Crawlability and indexing
- Confirm robots.txt is not accidentally blocking sections of the site that should be indexed.
- Check the XML sitemap is complete, up to date, and submitted in Google Search Console.
- Confirm the site is indexed correctly in Google Search Console with no unexpected 'excluded' pages.
- Review the Coverage/Pages report regularly for crawl errors, soft 404s or server errors.
- Make sure important pages are reachable through internal links, not only through the sitemap — pages with no internal links are harder for both users and crawlers to find.
Technical health
- Check for and fix broken links, both internal and to external sites.
- Ensure the site uses HTTPS throughout with no mixed-content warnings.
- Review Core Web Vitals in Search Console and address any pages flagged as poor.
- Confirm there is a single canonical version of every page (no duplicate URLs from tracking parameters or trailing slashes).
- Check that redirects from old URLs are in place and lead directly to the correct destination, without unnecessary redirect chains.
Page titles and headings
Every page needs a title tag that is unique, descriptive and written for the person searching rather than stuffed with repeated keywords. A useful test is whether the title alone, seen in a list of search results, would make sense and stand out to someone scanning quickly.
Heading structure should reflect the actual outline of the content: one H1 that states what the page is about, H2s for its main sections, and H3s for sub-points within those sections. Headings should not be used purely for visual styling — that is what CSS is for — because search engines and assistive technology both rely on heading structure to understand a page's organisation.
URL structure
URLs should be short, human-readable, and reflect where a page sits in the site's structure — a URL a person could reasonably guess or remember is usually a well-structured one. Avoid unnecessary parameters, session IDs or deeply nested folder structures for content that does not need them.
Once a URL is published and indexed, avoid changing it without a proper redirect in place; unmanaged URL changes are one of the more common causes of sudden, avoidable ranking and traffic loss during a redesign.
On-page fundamentals
- Every page has a unique title tag and meta description that accurately describes it.
- Heading structure is logical — one H1, with H2s and H3s used to organise sections, not for styling.
- Images have descriptive alt text and are compressed for fast loading.
- Internal links connect related pages using descriptive anchor text, not just 'click here'.
- URLs are short, readable and reflect the page's content.
Content quality and structure
As a site grows, content quality tends to become uneven — some pages are thorough, others were written quickly and never revisited. Audit your existing pages for ones that are thin, outdated or overlapping with each other, and either consolidate, expand or remove them.
New content should be planned against a clear content map so you are not accidentally creating multiple pages competing for the same search query — a common issue once a site passes fifty or so pages.
Good content answers a specific, real question thoroughly rather than mentioning many topics briefly. Before publishing, it is worth asking whether the page would still be genuinely useful to a visitor if it were the only page on your site they ever read.
Internal linking
Internal links do two jobs at once: they help visitors find related information, and they help search engines understand which pages on your site are most important and how they relate to each other. As new content is added, go back and link to it from relevant older pages, not only forward from the new page.
Watch for orphaned pages that have no internal links pointing to them at all — these are easy to lose track of as a site grows, and they are effectively invisible to both users navigating the site and to crawlers relying on links to discover content.
Image SEO
Every meaningful image should have alt text that describes it accurately for someone who cannot see it, which also gives search engines useful context. Purely decorative images do not need descriptive alt text, but they should still be marked appropriately rather than left with a missing attribute.
Compress images before uploading and use modern, efficient formats where your platform supports them. Oversized, unoptimised images are one of the most common and easiest-to-fix causes of a slow page.
Performance and mobile experience
Page speed and mobile usability affect both how visitors experience your site and how search engines evaluate it. Test key pages on an actual mobile device, not only in a desktop browser resized smaller, since real-world conditions like slower connections and touch interaction reveal issues that a resized browser window will not.
Common, worthwhile fixes include compressing images, removing unused scripts and fonts, deferring non-essential third-party scripts, and making sure tap targets like buttons and links are large enough to use comfortably on a phone.
Structured data and rich results
Where relevant, add structured data (schema markup) for things like FAQs, articles, products or local business details. This does not guarantee a ranking boost, but it helps search engines understand your content correctly and can enable enhanced listings in search results. Validate any structured data with Google's Rich Results Test before publishing.
Analytics and measurement
Confirm analytics and Search Console are correctly installed and reporting before relying on their data for decisions — a broken tracking snippet can quietly go unnoticed for months. Set up basic conversion tracking for the actions that matter to your business, such as form submissions or calls, so SEO performance can be tied back to actual business outcomes rather than traffic alone.
Pre-launch checks for new pages or a redesign
- Confirm the new or redesigned pages are not accidentally set to noindex before going live.
- Check that title tags, meta descriptions and headings are in place for every new page, not left as placeholders.
- Verify old URLs have redirects set up if the URL structure is changing.
- Run a broken-link check across the updated site before it goes live.
- Confirm structured data still validates correctly after any template or design changes.
Post-launch checks
- Recrawl or request indexing for key changed pages in Search Console.
- Monitor the Coverage report over the following weeks for any unexpected errors or drops in indexed pages.
- Check Core Web Vitals again once real user data has accumulated on the new pages.
- Compare organic traffic and rankings for key pages before and after the change, and investigate any unexpected drop promptly rather than waiting.
Ongoing monitoring
SEO health is not a one-time audit. Set a recurring quarterly review of Search Console data, broken links and page speed, and treat significant traffic drops on any page as a prompt to investigate rather than ignore.

- Assuming analytics is working correctly without periodically verifying it
Frequently asked questions
- How often should a growing business audit its website SEO?
- A quarterly review is a reasonable cadence for most growing businesses, with a deeper audit whenever the site undergoes a significant redesign, migration or rapid content expansion.
- Is structured data necessary for SEO?
- It is not a direct ranking factor, but it helps search engines interpret your content accurately and can enable rich results like FAQ snippets, which improve visibility and click-through in search results.
- What is the biggest SEO risk when a website grows quickly?
- Content and URL sprawl — multiple pages unintentionally targeting the same query, inconsistent structure, and technical debt accumulating faster than anyone reviews it. Regular audits catch this before it compounds.
- What should be checked immediately before a new page goes live?
- Confirm it is not set to noindex, that title tags, meta descriptions and headings are properly filled in rather than left as placeholders, and that any URL changes have redirects configured. A quick broken-link check across the updated area of the site is also worthwhile.
- How soon after launch should we check whether changes worked as intended?
- Request indexing for key changed pages promptly, then monitor Search Console's coverage and performance reports over the following weeks. Core Web Vitals data in particular needs some time to accumulate from real users before it is meaningful.
- Do orphaned pages actually hurt SEO?
- A page with no internal links pointing to it is harder for both visitors and search engine crawlers to discover, which limits its ability to be indexed, understood in context, or to pass and receive relevance from related pages. Regularly checking for orphaned pages as a site grows is a simple, effective habit.
- Should every page on the site have structured data?
- Only where it is genuinely applicable and accurate — for example, FAQ schema on a page that actually contains a visible FAQ, or Article schema on a genuine article. Adding schema that misrepresents a page's content is against structured data guidelines and can cause more harm than benefit.
Key takeaways
- Fix technical health before optimising on-page details.
- Audit existing content for thin or overlapping pages as the site grows.
- Use structured data where relevant, and validate it before publishing.
- Treat SEO health as a recurring quarterly review, not a one-time task.
- Watch Core Web Vitals — page experience affects both users and rankings.
- Run distinct pre-launch and post-launch checks whenever pages change significantly.
