Look, I am going to be straight with you, most SEO audit advice is bloated nonsense that tries to sell you a shiny tool you do not need, you can do a proper audit with Google Search Console and a few free helpers if you follow a simple process.
Here is the part that will save you time and money, those pricey monthly dashboards mostly repackage data you already have, you want fast fixes that actually move rankings, use free SEO tools, fix the obvious issues, then repeat on a schedule.
1. Check indexing in Search Console.
2. Crawl pages with Screaming Frog.
3. Test speed in PageSpeed Insights.
4. Verify mobile on a real phone.
5. Repair 404s and redirects.
6. Enforce HTTPS, add basic schema.
1. Verify Crawlability and Indexing
If Google cannot crawl or index your pages, nothing else matters, open Google Search Console, check the Page indexing report for errors like excluded by noindex or blocked by robots, then fix the cause and resubmit affected URLs, see Google Search Central on Page indexing.
Use the URL Inspection tool on key pages, confirm the canonical, confirm last crawl, and request indexing after a fix, submit a fresh XML sitemap if you have not already, if you need a deeper walkthrough on index issues, read our plain language guide how to resolve indexation problems.
2. Analyze Site Structure and Internal Links
Crawlers follow links, people do too, run a crawl with Screaming Frog free version, up to five hundred URLs, look for orphan pages, deep click depth, and weak anchor text on important links, see Screaming Frog on SEO Spider, then add sensible internal links from strong pages to the ones that make you money.
If a page is not getting indexed or has zero traffic, nine times out of ten it is buried, link it from your navigation or a relevant hub, keep the anchor descriptive, not cute, and avoid dumping fifty
links on one page, if you want more practical content tips while you tidy structure, check our SEO tips and guides.
3. Speed Up Your Site, Page Speed and Core Web Vitals
Your site feels slow because it is, run PageSpeed Insights on your top pages, tackle image bloat, unused JavaScript, and server response time, Google explains how PSI scores and suggestions work here, see Google on PageSpeed Insights, Google also reports that fifty three percent of visits bail if a mobile site takes longer than three seconds to load, see Think with Google on mobile site speed.
Quick wins that do not require a developer, compress and resize images, enable lazy load, minify CSS and JS, remove junk plugins, consider a free CDN if your host is sluggish, if you are cleaning up old content while you speed things up, this pairs well with our piece on why content pruning can boost SEO, your users will feel the difference and so will your rankings.
4. Ensure Mobile Friendliness
Google uses the mobile view to evaluate pages, test your key pages on an actual phone, then review Core Web Vitals and mobile performance in PageSpeed Insights and Search Console, fix tiny fonts, cramped buttons, off screen content, and annoying popups, if you want a sanity check on broader strategy while you fix mobile basics, skim our guide on building a content strategy for SEO.
5. Verify HTTPS and Site Security
Browsers flag insecure sites, that looks sketchy to users and to Google, make sure every page loads over HTTPS, no mixed content, if anything still loads over http, update those URLs and force a redirect to https, once done, resubmit your sitemap and spot check with URL Inspection, if this part sounds like a pain in the ass, ask us and we will point you to a simple checklist on the call.
6. Find and Fix Broken Links, 404s and Redirects
Nothing kills trust like dead ends, crawl your site and filter for 4xx errors, fix internal links, then
301 redirect removed URLs to the closest relevant page, avoid redirect chains where A goes to B then to C, update links to point straight to C, for a second source of truth, check Not Found issues in Search Console, and if you want an expert to sanity check a messy redirect map, book our SEO consulting services.
Here is the truth agencies hide, a few 404s will not tank you, but a cluster of broken links wastes crawl budget and annoys people, clean it up, keep it clean, re crawl after big site changes, and watch session length improve when visitors stop hitting walls.
7. Add Structured Data for Rich Results
Schema is not magic, it helps Google understand what your page is, add relevant structured data like FAQ on this page or Organization on your site, validate with the Rich Results Test, and only mark up what is actually on the page, start here, see Google on structured data.
Bonus, Use Microsoft Clarity for User Behavior
This is where I call out the industry, most audits ignore what real people do, install Microsoft Clarity, it is free, watch heatmaps and session recordings, look for rage clicks and dead clicks that signal broken elements or confusing layouts, for a primer with recent tips see Search Engine Land on Microsoft Clarity, when you fix what people actually struggle with, conversions climb.

FAQ
How often should I perform a technical SEO audit
For most small sites, run a full technical SEO audit every three to six months, also audit after a redesign, a migration, or when traffic drops for no obvious reason.
Which free tools do I actually need
Use Google Search Console for indexing and issues, Google on PageSpeed Insights for performance, Screaming Frog on SEO Spider for crawling up to five hundred URLs, and Search Engine Land on Microsoft Clarity for behavior insights.
Can I do this without hiring an agency
Yes, if you can follow a checklist and stay patient you can run a solid DIY audit, if your site is huge or the problems are gnarly, get help on the hard parts and keep the routine checks in house.
Are paid tools worth it
Sometimes, for crawling very large sites and competitor research they can save time, for a small or mid size site, the free stack does the job, most paid tools are fine, a few are garbage, do not sign contracts you do not need.
Will these fixes improve rankings
Fixing crawl blocks, speed, mobile issues, and broken links removes the technical ceiling that holds you back, rankings move when search engines can reach and understand fast pages that people actually use, content and links still matter, this work makes them count.
