The Technical SEO Checklist to Run Before You Publish More Content

When organic traffic stalls, the instinct is often to publish more. But if search engines can't reliably crawl, render, and understand the pages you already have, new content inherits the same problems.

This checklist covers the technical foundations we review first in every SEO engagement. You don't need specialist tools for most of it — Google Search Console and a site crawler will get you a long way.

1. Can search engines find your pages?

Start with discovery. Search engines find pages through links and sitemaps.

• Submit an XML sitemap in Google Search Console and check that it only contains canonical, indexable URLs that return a 200 status.
• Check robots.txt for rules that accidentally block important sections, scripts, or stylesheets.
• Look for orphan pages — important pages with no internal links pointing to them. If you can only reach a page through the sitemap, search engines may treat it as unimportant.

2. Are the right pages being indexed?

Open the Pages report (page indexing) in Search Console. It tells you which URLs are indexed and why others aren't.

Pay particular attention to:

• "Crawled – currently not indexed" and "Discovered – currently not indexed", which often point to thin, duplicated, or low-priority content.
• Unexpected noindex tags, frequently left behind after a site launch or redesign.
• Soft 404s — pages that return a 200 status but look empty or like an error to Google.

3. Is there one clear version of each page?

Duplicate URLs split signals and waste crawling. Common sources include:

• HTTP and HTTPS, or www and non-www, both resolving.
• Trailing-slash and non-trailing-slash versions.
• URL parameters from filters, sorting, tracking, or session IDs.
• Printer-friendly or paginated variants.

Choose one preferred version, redirect the others with permanent (301) redirects where possible, and use a canonical tag pointing to the preferred URL. Make sure canonical tags, internal links, and your sitemap all agree with each other.

4. Does your content render without problems?

Google can render JavaScript, but rendering is resource-intensive and things can go wrong. Use the URL Inspection tool in Search Console to view the rendered HTML and confirm that:

• Main content and internal links appear in the rendered page.
• Important content doesn't depend on user interaction (such as a click) to load.
• Titles, meta descriptions, and canonical tags aren't overwritten incorrectly by JavaScript.

Server-side rendering or static generation removes most of this uncertainty, which is one reason we favour them for marketing websites.

5. Is the site architecture helping or hurting?

A clear structure helps both visitors and search engines understand which pages matter most.

• Keep important pages within a few clicks of the homepage.
• Group related content into logical sections, and link between pages on related topics.
• Use descriptive anchor text in internal links instead of "click here".
• Fix broken internal links and redirect chains — they waste crawl budget and dilute signals.

6. Are titles, headings, and metadata doing their job?

These are small details with outsized impact.

• Every indexable page should have a unique, descriptive title tag that reflects the main topic.
• Use one clear H1 and a logical heading structure beneath it.
• Write meta descriptions that accurately summarize the page. They don't directly affect rankings, but they influence whether people click.

7. Is structured data implemented correctly?

Structured data (schema markup) helps search engines interpret your content and can make pages eligible for enhanced search results. Common types for service businesses include Organization, LocalBusiness, Service, BreadcrumbList, and Article.

Validate your markup with Google's Rich Results Test and the Schema Markup Validator, and only mark up content that is actually visible on the page.

8. Is the site fast and mobile-friendly?

Google uses mobile-first indexing, so the mobile version of your site is the one that matters. Check the Core Web Vitals report in Search Console and fix template-level issues first. Our Core Web Vitals guide covers the most effective fixes.

9. If you serve multiple countries or languages

International sites need extra care:

• Choose a clear URL structure — country-code domains, subdomains, or subfolders.
• Implement hreflang annotations correctly, including return links and a self-reference on each page.
• Don't automatically redirect visitors based on their IP address without giving them a way to choose; it can stop search engines from seeing all versions of your site.

Prioritize ruthlessly

A technical audit will always find more issues than you can fix at once. Rank each finding by impact (how many important pages it affects) and effort, then work through the high-impact, low-effort items first.

Most importantly, fix the cause, not the symptom. If a CMS template generates duplicate URLs, fixing the template is better than redirecting thousands of URLs one at a time.

If you'd like help working through an audit, our SEO services start with exactly this kind of technical review.
