Most websites lose organic traffic to problems nobody is watching. A template change adds a noindex tag, a migration leaves a thousand broken redirects, a plugin update slows every page, or a competitor quietly builds better content on your best terms. An SEO health check is a structured inspection that surfaces these issues before they become quarter-long declines, and turns a vague sense that "traffic feels down" into a prioritised list of things to fix.

How AAMAX.CO Delivers SEO Health Checks and Audits

At AAMAX.CO, we run SEO health checks as a diagnostic with a decision attached, not a hundred-page export nobody reads. Our team crawls the site, cross-references Search Console and analytics data, tests performance on real devices, reviews content against competing pages, and then delivers findings ranked by revenue impact and implementation effort. If you would rather not assemble the tooling and interpret the results yourself, our SEO services include a full audit and a roadmap your development and content teams can execute directly.

Start With Indexing, Because Nothing Else Matters First

Before analysing anything, confirm that search engines can see your site. In Google Search Console, open the Pages report and review which URLs are indexed and, more importantly, why others are excluded. Look for pages marked noindex, blocked by robots.txt, canonicalised to another URL, or crawled but not indexed. Compare the indexed count against your actual page count; a large gap in either direction is a signal. A page that cannot be indexed cannot rank, no matter how well written it is, so this always comes first.

Check Crawlability and Site Architecture

Next, crawl the site with a dedicated tool and examine what a bot experiences. Review your robots.txt for rules blocking resources that are needed to render pages. Confirm your XML sitemap contains only canonical, indexable URLs and is submitted. Look at click depth, since pages buried five levels from the homepage receive very little internal authority. Identify orphan pages with no internal links, broken internal links, and redirect chains or loops. Then confirm that one canonical version of the site is served, with HTTP, www, trailing-slash, and mixed-case variants all redirecting consistently.

Assess Performance and Core Web Vitals

Speed is both a ranking factor and a conversion factor. Use the Core Web Vitals report for field data from real users, then a lab tool to diagnose specific causes on your most important templates. Focus on the metrics that matter: largest contentful paint, interaction latency, and layout stability. The usual culprits are oversized images, render-blocking scripts, excessive third-party tags, missing dimensions on media, and slow server response. Test on a mid-range mobile device over a normal connection, because desktop results on fast broadband hide most problems.

Review On-Page Fundamentals at Scale

Export titles, meta descriptions, headings, and canonical tags for every URL, then look for patterns rather than individual errors. Find missing or duplicated titles and descriptions, pages with several H1 tags or none, headings used purely for styling, images without alt text, and thin pages with very little unique content. Check that internal anchor text is descriptive instead of endless "click here" links. Pattern-level problems usually trace back to a template, which means one fix can correct hundreds of pages at once.

Audit Content Quality and Cannibalisation

Now evaluate the content itself. Map your pages to the queries they attract in Search Console, and look for cannibalisation where several URLs compete for the same intent and none rank well. Identify decaying pages that once performed and have slipped, which are usually your fastest wins through refreshing rather than rewriting. Compare your top commercial pages against the results currently outranking them and note what they cover that you do not. Then decide, page by page, whether to improve, consolidate, redirect, or remove.

Examine Your Backlink Profile

Authority still separates near-identical pages. Review your referring domains for relevance and quality, watch for sudden spikes of low-quality links, and check whether your most important commercial pages have any external links at all, since many sites accumulate links only to the homepage and blog. Look for broken backlinks pointing at dead URLs, which can be reclaimed with a redirect, and unlinked brand mentions worth pursuing. Compare your profile against two or three direct competitors to gauge the realistic gap on competitive terms.

Do Not Skip Local, Mobile, and Structured Data

If you serve a geographic market, verify that your business listing is complete and accurate, that your name, address, and phone number are consistent across the web, and that location pages carry genuinely unique content rather than a template with the city swapped. Check that structured data validates without errors and reflects what each page actually is. Test key user journeys on a phone, including navigation, forms, and checkout, because mobile usability problems suppress conversions long before they affect rankings.

Turn Findings Into a Prioritised Plan

An audit is only valuable if it changes what you do next. Score each issue by potential impact and by effort, then sequence the work. Indexing blocks and traffic-losing regressions come first, followed by template-level fixes that affect many pages, then content improvements to high-impression low-click pages, then longer-term authority building. Assign owners and dates, and re-run the core checks quarterly so you catch the next regression early. Consistent monitoring like this is what keeps organic search a reliable channel inside a broader digital marketing programme.

Final Thoughts

An SEO health check is not a one-time cleanup; it is routine maintenance for an asset that competitors are actively attacking. Confirm indexing, verify crawlability, measure performance, review on-page patterns, audit content and links, and check local and structured signals. Then act in order of impact rather than order of discovery. Sites that audit regularly rarely suffer sudden collapses, because the problems are found while they are still small.
