Auditoria técnica de SEO: 10 etapas para achar problemas

In my many years working with websites, I’ve learned one truth: what you can’t see can hurt you. It often hides in code, server settings, or behind little warning signs on your browser. That’s why a technical SEO audit matters so much. The Best SEO blog was created to help people like me and you spot issues before they stop your site from climbing the Google ladder.

SEO wins start with what’s under the hood.

Here, I’m sharing the ten-step roadmap I use to find technical roadblocks. No advanced degree required—just careful attention to detail and a willingness to look beneath the surface. Everything connects back to what The Best SEO aims for: clearer sites, higher ranks, happier audiences.

Step 1: Check site crawlability and indexation

The first thing I do is see if search engines can actually reach and understand your pages. You can start simple: put your domain into a search engine with site:yourdomain.com and see what pops up. Are key pages missing?

Review your robots.txt file. Sometimes it’s blocking Google unintentionally.
Glance through your sitemap.xml for errors, outdated URLs, or pages that shouldn’t be indexed.
Make sure no critical URLs have a noindex tag by mistake.

This step is the backbone for everything else. If Google can’t find you, nothing else matters.

Step 2: Identify crawl errors and broken links

In my audits for clients and my own sites, I keep an eye out for 404 errors or redirected loops. These trip up both search engines and users.

Test top pages manually and with tools to spot 404 and 500 errors.
Scan for broken internal and external links, these are lurking loss points for trust and SEO.
Check for redirect chains (301s following other 301s), which chip away at crawling and rankings.

Keeping your link structure clean builds a smoother experience for users and bots alike.

Step 3: Review site speed and performance

Nothing turns visitors away like a slow website. Page speed checks are front and center in my routine—search engines measure this as a ranking signal.

Measure loading times for desktop and mobile (aim for well under 3 seconds).
Look at what’s slowing pages down: images too heavy, bulky scripts, server lag?
Test your website’s Core Web Vitals scores. These include Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS).

Fast sites keep people engaged and help conversions grow.

Step 4: Evaluate mobile usability

Mobile traffic makes up at least half of visits for most of my audits. So, your site must shine on smartphones and tablets, not just desktop screens.

Test your site on several devices and screen sizes—menus, images, buttons should all work smoothly.
Look for clickable elements that are too close together.
Check if text is too small or sections require too much zooming and scrolling.

Mobile-friendly sites get prioritized in Google searches and bring in more visitors.

Step 5: Check for HTTPS and security

People trust secure websites more. Browsers will warn visitors if your page isn’t protected. In every technical audit I’ve done, I flag missing HTTPS as a risk.

Make sure the entire site, not just the home page, uses HTTPS.
Check for mixed content warnings caused by insecure images or scripts.
Update or renew SSL certificates before they expire.

Search engines prefer sites that protect their visitors.

Step 6: Spot duplicate content and thin pages

Google doesn’t like seeing the same content in several places on your site. Duplicate and thin pages can weaken your whole site’s authority.

Find URLs with similar or identical content and use canonical tags to fix them.
Identify thin content (pages with little substance) and either improve or remove them.
Look for boilerplate text repeated across multiple pages—unique content beats copy-paste every time.

Trim the fluff. You’ll see your rankings breathe a little easier.

Step 7: Inspect structured data and schema markup

Structured data helps search engines understand your content. I always scan for proper use of Schema.org tags.

Mark up business details, reviews, products, or articles as needed for your niche.
Test these markups to make sure they generate no errors or warnings in structured data testing tools.
Fix any implementation problems—wrong or missing fields can cost you rich results in Google.

When done right, structured data helps you stand out in search results with rich snippets.

Step 8: Review internal linking and site structure

A logical, easy-to-follow internal linking structure does wonders. When I map out a site, I look for loose ends and missed connections.

Check if your most important pages are linked from menus, footers, or related articles.
Find and fix orphaned pages (those with no internal links pointing to them).
Make it easy for users and bots to explore longer visit paths.

Step 9: Check for proper use of headings and metadata

Search engines pay attention to your page titles, descriptions, and how you use headings. These aren’t just for robots—they guide real people, too.

Every page should have a unique, descriptive <title> and meta description.
Use headings (H1, H2, H3) in a logical order—not just for style, but to signal content hierarchy.
Avoid stuffing too many keywords—you want clarity, not clutter.

Pages with strong, clear metadata have a better shot at ranking well.

Step 10: Audit for outdated plugins and tech

This step gets overlooked more often than I’d like. Old plugins or unsupported CMS versions are magnets for errors and security threats.

Update all plugins, themes, and core site software to current versions.
Delete anything unused. Old add-ons can slow the site and cause mysterious bugs.
Check compatibility after each update to keep your site running smoothly.

Staying up to date keeps technical gremlins at bay.

Putting it all together: My audit workflow

When I perform a technical SEO audit, I write down findings for each step and fix things as I go. I recommend repeating this audit every few months or after any major site change. If you want broader strategies, The Best SEO’s posts in SEO basics and digital marketing are a great next stop.
