What is an SEO check?
An SEO check is an examination of how well your website gets found in Google, and increasingly in AI search engines like ChatGPT and Google AI Overviews. The terminology blurs in practice. An SEO scan usually means the quick, automated version: you enter a URL and get a score. An seo audit goes deeper: a person looks at the data and draws conclusions from it.
That score deserves an immediate caveat. A website can score 90 out of 100 in a free tool and still sit on page three. The reverse happens too. The score measures whether your technical basics are in order, not whether your pages answer your customer’s search intent or whether competitors hold stronger backlinks. More on that below.
What does a serious SEO scan measure?
A serious SEO scan looks at four pillars. The first three are classic. The fourth is new, and it is exactly where most free tools fall short.
Load speed, Core Web Vitals, indexing and crawlability. Can Google read your site and find every page?
Do your pages answer the search intent? Are titles, headings and internal links structured properly?
Your backlink profile: who links to you, and does Google trust those sites? Often the difference between page two and page one.
Do ChatGPT, Perplexity and AI Overviews mention and cite you when someone asks about your kind of service?
Technical health: Core Web Vitals and indexing
The technical foundation decides whether Google can properly read your site at all. A good SEO check measures your Core Web Vitals (load speed, stability and interactivity), verifies that your important pages are indexed, and hunts down blockers: broken links, wrong redirects, missing sitemaps. It sounds dull, but this is where most quick wins hide. Our guide to technical SEO covers how to get this layer structurally right.
Content: search intent and structure
Content is where tools stop and thinking starts. The question is not whether your keyword appears often enough on the page, but whether the page gives the right answer to what someone is looking for. Someone typing “seo check” wants to test their website. Someone typing “outsource SEO” wants a partner. Two completely different pages. A proper content review puts your most important pages next to the search intent and the structure: do the titles, headings and internal links hold up? More in how to rank higher in Google.
Authority: your backlink profile
Google trusts sites that other trusted sites vouch for. An SEO check therefore maps your backlink profile: how many domains link to you, how relevant they are, and how that compares to your direct competitors. This is the pillar you control the least and the one that moves the slowest. Which is exactly why you want to know where you stand before you invest time anywhere.
AI visibility: do ChatGPT and AI Overviews cite you?
This is the pillar that makes the difference in 2026, and almost no free tool measures it. More and more buyers ask ChatGPT, Perplexity or Gemini for a shortlist before they ever reach your site. If you are not in that answer, you do not exist for that buyer. A modern SEO check therefore verifies whether AI search engines know your brand, whether your content gets cited in AI Overviews, and whether your markup is readable for AI agents. We unpack this field in what is AIO and in our guide to AI SEO services.
Run a free seo check yourself in 30 minutes
You do not need to hire anyone to know roughly where you stand. With this checklist and five free tools, you get an honest first picture within half an hour.
| Minutes | Check | Free tool |
|---|---|---|
| 0 to 5 | Load speed and Core Web Vitals | PageSpeed Insights |
| 5 to 10 | Indexing: are your pages in Google? | Google Search Console or a site:yourdomain.com search |
| 10 to 15 | Search intent: does your key page answer the question? | Google itself: study who currently wins your keyword |
| 15 to 20 | Titles and meta descriptions of your top 5 pages | Free SERP preview tools or the search results themselves |
| 20 to 25 | Backlink profile versus one competitor | Ahrefs’ free backlink checker |
| 25 to 30 | AI visibility: ask ChatGPT for recommendations in your category | ChatGPT or Perplexity |
Most business owners underestimate that last step. Ask ChatGPT literally: “which companies would you recommend for [your service] in [your region]?” If you are not on the list, you know what to work on.
Search Console is your most honest source
Free scans estimate, Google Search Console measures. It shows exactly which queries you appear for, at what position, and how often people click. No Search Console connected yet? Do it today. It is free, and it is the data layer every serious seo audit runs on.
Rather have a senior specialist take a look?
Request the free SEO scan. You get a concrete analysis of technical health, content, authority and AI visibility, with your three biggest opportunities on top. No obligations attached.
What an automated SEO check misses
Automated tools are good at counting and bad at choosing. They find every missing alt text, but they do not see that your most important service page serves the wrong search intent. They hand you a hundred findings without an order, while maybe three of them touch your revenue.
What a tool cannot see:
- Priority. Which of the hundred findings actually brings in customers? A specialist picks three; a tool gives you a laundry list.
- Competitive context. A score means nothing until you know how the number one for your keyword scores.
- Search intent. No crawler can judge whether a page gives the right answer.
- Strategy. Where are the keywords you can realistically win with your current authority?
The old fix for this was manpower. Traditional SEO for a large company could easily run €20,000 per month: an army of copywriters, a branding specialist and endless meetings about blog content. Expensive and slow. The other extreme fails too: fully automated SEO never reaches page one, because Google and AI search engines reward genuine quality and strategy.
Viralistic works semi-automatically instead. Senior specialists with years in the field keep the eagle-eye view on strategy and quality, while automation handles the repetitive work. That is why SEO trajectories range from €650 per month (excl. VAT) for a very small project to about €5,000 per month for larger companies. Far below the traditional cost, with more quality per euro. How to choose such a partner is covered in choosing an SEO agency.
An SEO score of 90 does not mean people find you
Free tools measure what is measurable: technical health and on-page basics. Authority, search intent and AI visibility weigh heavier, but they never show up in the number. Treat the score as a thermometer, not a diagnosis.

Frequently asked questions
What is an SEO check?
An SEO check is an analysis of how well your website gets found in Google and AI search engines. It measures four pillars: technical health (speed, indexing), content (search intent, structure), authority (backlinks) and AI visibility (citations in ChatGPT and AI Overviews).
How much does an SEO check cost?
An automated SEO scan is usually free. A manual seo audit by a specialist typically costs €500 to €2,000 in the Dutch market. Viralistic offers a free SEO scan performed by a senior specialist as an introduction, with no obligations.
Can I run an SEO audit myself?
The basics, yes. With PageSpeed Insights, Google Search Console, Ahrefs’ free backlink checker and a test question to ChatGPT, you get an honest first picture in 30 minutes. Interpretation, prioritisation and competitor analysis take experience.
What is the difference between an SEO scan and an SEO audit?
An SEO scan is automated: a tool crawls your site and returns a score. An SEO audit is manual work: a specialist analyses the data, compares it to competitors and turns findings into a priority list. The scan signals; the audit explains.
Does my website appear in ChatGPT and AI Overviews?
Test it: ask ChatGPT or Perplexity for recommendations in your category and region. If you are not mentioned, you usually lack authority, clear brand information or agent-readable content. This is the territory of AIO.
How often should you run an SEO check?
A short check every quarter is enough for most companies, plus a thorough audit after big changes: a new website, a migration or a drop in traffic. If you work on SEO actively, you monitor continuously through Search Console and live reporting.
