Technical SEO Audit: What to Fix First

Run any website through an SEO crawler and you'll get a report with hundreds, sometimes thousands, of warnings. Missing alt text, long titles, redirect chains, duplicate meta descriptions. The problem isn't finding issues. It's knowing which ones hold your site back, and which ones you can safely ignore.

This guide walks through the technical areas in the order they matter: first making sure Google can find and index your important pages, then helping it understand them, then making them fast and trustworthy. Work through them in this order and you'll fix the problems that cost traffic before the ones that simply look untidy.

1. Can Google crawl and index your important pages?

Nothing else matters if your key pages aren't in Google's index. Start with the Page indexing report in Google Search Console and check whether your most valuable pages, such as service pages, product categories and top articles, are indexed.

• Check robots.txt for rules that accidentally block important sections.
• Look for stray noindex tags, often left behind after a site launch or redesign.
• Make sure your XML sitemap lists only live, indexable pages, and is submitted in Search Console.
• Confirm canonical tags point to the version of each page you want to rank.

2. Does your site structure help or hurt?

Search engines judge a page's importance partly by how it's linked. Pages buried five or six clicks from the homepage, or pages with no internal links at all, tend to be crawled less often and rank less well.

• Keep important pages within three clicks of the homepage.
• Find orphan pages, which have no internal links pointing to them, and link to them from relevant pages.
• Use descriptive anchor text in internal links, rather than 'click here'.
• Control faceted navigation and filter URLs on ecommerce sites so they don't create thousands of near-duplicate pages.

3. Duplicate and thin content

When several pages cover the same topic, they compete with each other and none ranks as well as a single strong page would. Look for pages targeting the same keyword, near-identical location or product pages, and short pages that add little value. Consolidate them with redirects, merge the best content into one page, or give each page a distinct purpose.

4. Page experience and Core Web Vitals

Speed and stability affect both rankings and conversions. Google's Core Web Vitals measure three things, and a good result on each is the target:

• Largest Contentful Paint (LCP): how quickly the main content appears. Aim for 2.5 seconds or less.
• Interaction to Next Paint (INP): how quickly the page responds when someone clicks or taps. Aim for 200 milliseconds or less.
• Cumulative Layout Shift (CLS): how much the layout jumps around while loading. Aim for 0.1 or less.

Use field data from Search Console, which reflects real visitors, rather than relying only on lab tests. The usual culprits are oversized images, heavy third-party scripts, unoptimized web fonts and elements that load without reserved space.

5. Structured data

Structured data helps search engines understand what a page is about, whether that's an organization, a product, an article or a set of FAQs, and can make pages eligible for richer search results. Add the schema types that match what's on the page, validate them with Google's Rich Results Test, and avoid marking up content that isn't visible on the page.

6. Redirects, status codes and broken links

• Fix internal links that point to 404 pages or to redirects, and link directly to the final URL.
• Replace redirect chains with a single redirect wherever possible.
• Use permanent 301 redirects for pages that have moved for good.
• After a redesign or migration, check that every old URL with traffic or backlinks redirects to its closest match.

How to prioritize your fixes

Score each issue on two things: how much traffic or revenue it affects, and how much effort it takes to fix. Start with high-impact, low-effort fixes on the pages that matter most to your business. An indexing problem on a key service page is worth more than a thousand missing alt tags on old blog posts.

Then fix issues at the template level wherever you can. Correcting a problem in a product page template fixes it on every product at once, which is far more efficient than editing pages one by one.

Your next step

Open Search Console today and check whether your ten most valuable pages are indexed and passing Core Web Vitals. That short check often reveals the biggest opportunity on the site. For a complete, prioritized picture, a technical SEO audit will rank every issue by its likely impact on traffic and revenue.
