Checking SEO optimization is one of those tasks that sounds simple and turns into a rabbit hole. Run any free website grader and you will get a score out of one hundred, a long list of warnings and no idea which of them matter. Meanwhile the actual reason your site is not ranking might be something the tool never mentioned. A proper SEO check is not a score, it is a diagnosis: can search engines find and understand your pages, are those pages the best available answer for the queries you care about, and does your site have enough credibility to compete. This guide walks through how to check SEO optimization systematically, using tools that are mostly free, in the order that surfaces real problems first.

How We at AAMAX.CO Audit and Fix What We Find

An audit is only valuable if it leads to action, and that is where most self-checks fall apart: people end up with a spreadsheet of two hundred issues and no sense of priority. At AAMAX.CO we run structured audits as the starting point of our search engine optimization work, then rank every finding by likely impact against effort so the highest-value fixes happen first. You get a clear roadmap, implementation support and measurable reporting rather than a raw issue dump. If you want a professional read on where your site actually stands and what to do about it, hire AAMAX.CO and we will audit, prioritise and execute.

Start With Indexation: Can Your Pages Be Found at All

Everything else is irrelevant if your pages are not indexed. Open Google Search Console and go to the Pages report under Indexing. Compare the number of indexed pages against the number of pages you believe you have. A large gap in either direction is a red flag: too few means pages are being excluded, too many usually means duplicate or thin pages are being generated somewhere.

Read the exclusion reasons carefully. Discovered but not currently indexed often signals quality or crawl budget problems. Excluded by noindex tag means someone deliberately or accidentally blocked the page. Duplicate without user-selected canonical means you have multiple versions of similar content competing. Alternate page with proper canonical tag is usually fine. Also check your robots file for accidental broad blocks and confirm your sitemap has been submitted and is being read successfully.

Check Technical Health and Core Web Vitals

Next, look at how the site performs and whether it renders correctly. Use the Core Web Vitals report in Search Console for real-world field data, then use a page speed testing tool on your most important individual pages for diagnostics. Focus on the three headline metrics: how quickly the main content appears, how responsive the page is to interaction, and how much the layout shifts while loading.

The usual culprits are large uncompressed images, blocking scripts, heavy third-party embeds, excessive custom fonts and elements without reserved dimensions. Also verify mobile usability, since mobile is what gets indexed. Load your site on an actual phone, not just a resized browser window, and check that text is readable, taps hit their targets, nothing overflows horizontally and interactive elements work.

Then crawl the site with a crawler tool to find broken internal links, redirect chains, missing titles, duplicate titles, orphaned pages with no internal links pointing at them, and pages several clicks deep that should be more prominent.

Audit On-Page Optimization Page by Page

For your most important pages, check the fundamentals individually. Does the page have a unique title tag that leads with the term you want to rank for and fits within the visible length. Does it have a unique, persuasive meta description. Is there exactly one top-level heading that clearly states the subject. Are subheadings used to structure the content logically rather than chosen for their visual size.

Look at the URL: short, lowercase, hyphenated and descriptive. Check images have meaningful alt text and sensible filenames. Confirm the primary keyword appears naturally in the opening paragraph, in at least one subheading and throughout the body without stuffing. Verify there is relevant structured data for the page type. Finally, check for keyword cannibalisation by searching your own site for each target term. If several pages target the same query, consolidate them.

Assess Content Quality Honestly

This is the part tools cannot do for you. Open the top three results for a keyword you want to win, then open your page beside them. Ask which one you would rather read if you were the searcher. Be brutal.

Look for depth: does your page cover the subtopics and follow-up questions the competing pages address. Look for originality: does it contain anything the others do not, such as your own data, real examples, clear pricing, screenshots or a genuinely useful process. Look for clarity: can someone skim the headings and get the answer. Look for freshness: is anything factually out of date. Thin pages that exist only to target a keyword are a liability, not an asset, and consolidating or removing them frequently improves overall site performance.

Review Backlinks and Authority Signals

Use a backlink tool to check the number of unique referring domains, their relevance and their quality trend over time. What matters is not raw link count but how many distinct, credible, topically relevant sites reference you. Compare your referring domain count against the pages currently outranking you. If they have vastly more relevant links, no amount of on-page tweaking will close that gap on its own.

Watch for warning signs too: sudden spikes of low-quality links, links from unrelated foreign-language sites, or heavily repeated exact-match anchor text. Alongside links, check trust signals a human evaluator would look for: named authors with real credentials, visible contact details, an about page, customer reviews and clear policies.

Check Local SEO If You Serve an Area

If you have a physical location or service area, verify that your Google Business Profile is claimed, complete and accurate, with the right categories, hours, service areas and photos. Confirm your business name, address and phone number are identical across your website, your profile and major directories. Inconsistent details across the web are one of the most common reasons local businesses underperform. Review recency and volume matter as well, so check whether you are actively earning reviews or letting the profile stagnate.

Measure the Metrics That Actually Matter

Finish by looking at outcomes rather than scores. In Search Console, review total impressions and clicks over the last six months for direction of travel. Identify queries where you rank between positions five and twenty, because those are your fastest opportunities. Find pages with high impressions and low click-through rate, which usually need better titles and descriptions rather than more content.

In your analytics platform, look at organic sessions, the pages they land on and, most importantly, whether that traffic converts. A ranking that brings visitors who never enquire is not a win. Set a monthly review rhythm so you are tracking trends rather than reacting to daily fluctuations. As AI answer engines take a larger share of discovery, add a new check to your routine: search your key questions in AI assistants and see whether your brand is cited. Improving that visibility is the focus of our GEO services, and it fits naturally alongside a broader digital marketing measurement framework.

Final Thoughts

Checking SEO optimization properly means working through layers in order: indexation first, then technical health, then on-page elements, then honest content comparison, then authority, then local signals, then outcome metrics. Free tools cover most of it, and the discipline matters more than the software. Ignore the vanity score, find the two or three issues genuinely holding you back, fix those, and re-check in a month. That loop, repeated, is what moves a site up the results.
