Many website SEO checkers are good at finding things and weak at ranking what matters.
You get a score, a long list of warnings, and no real answer to the only question that counts:
- what should I fix first
That is why I prefer a shorter check that separates eligibility, targeting, and trust before the report turns into noise.
Short answer
To check a website for SEO issues, start with the final page response and indexability, then review the title tag, meta description, H1-H3 structure, visible copy, canonical ownership, internal links, image alt text, and structured data.
The point is not to collect every issue a tool can name. The point is to work out whether the page is blocked by technical signals, too weak for the keyword it is targeting, or simply unsupported by the rest of the site.
If you want a fast page-level pass first, use the free website SEO checker. This article explains how to judge what that kind of check is actually telling you.
Start with one important page
Business owners often make the same mistake:
they try to audit the whole site before deciding which page matters most.
Start with one page that should generate something meaningful:
- a service page
- a local landing page
- a comparison page
- a revenue-driving article
You can broaden the audit later. The first useful question is whether an important page is healthy enough to compete.
Step 1: check whether the page is actually eligible to rank
Before you worry about copy, confirm that the page can qualify for search at all.
Check:
- does the final URL return 200
- are there redirects in the path
- is there a noindex directive
- does the canonical point to itself or to another page
- is the page blocked in a way that prevents normal crawling
If these signals are wrong, the page can look fine and still underperform.
This is the first split I care about:
- the page is weak because it cannot compete
- the page is weak because it is not eligible enough to compete
Those are different queues.
Step 2: check whether the title and H1 are targeting the same job
I see this problem constantly on sites that "seem optimized."
The title tries to rank for one thing. The H1 names another. The intro talks around the topic. The page then wonders why Google picked a different URL instead.
Ask:
- does the title tag name the page's real topic
- does the H1 reinforce the same topic
- does the intro make the offer or answer clear
- would a buyer know within a few seconds what the page is for
If the targeting is fuzzy, the page often loses before the deeper audit even starts.
Step 3: read the page like a buyer, not a crawler
Some pages are technically clean and still weak.
That usually means the page does not answer the obvious next question well enough. It may be too generic, too abstract, too thin, or too late getting to the point.
I would look for:
- a clear explanation of what the page offers
- enough detail to trust it
- proof that feels connected to the claim
- a sane heading structure
- a next step that matches the page intent
This is where many reports stay shallow. They name missing fields. They do not judge whether the page deserves to win.
Step 4: check internal support
A page does not compete alone.
I want to know:
- which important pages link to it
- whether the anchors describe it clearly
- whether the page sits inside a useful hub or service path
- whether it is orphaned from the parts of the site that carry authority
Internal links do two jobs here:
- they help discovery
- they tell search engines and users what role the page plays
If the page is structurally isolated, the site is quietly voting against it.
Step 5: check the support signals after the bigger issues
This is where image alt text, structured data, and smaller markup details belong.
They matter. They usually do not belong at the top of the queue unless the page is already strong in the bigger areas.
Review:
- image alt text where it helps understanding
- structured data that matches the visible content
- obvious metadata gaps
- whether FAQs are present only when they earn the space
The mistake is treating these as the main fix when the page still has weak ownership or thin substance.
Step 6: compare the page against the pages already winning
If the page is meant to rank for a commercial term, compare it with the top results.
I am not looking for word count.
I am looking for:
- what the winning pages answer early
- how they structure the page
- what proof they show
- what kind of intent they are satisfying
- whether your page is trying to do a different job from the query
That comparison often exposes the real issue faster than another checklist.
What a free website SEO checker can and cannot tell you
A good website SEO checker is useful for first-pass diagnosis.
It can quickly show you whether the page has obvious problems with:
- response status
- redirects
- titles and headings
- canonicals
- noindex hints
- internal links
- image alt text
- structured data
It cannot replace:
- ranking data
- Search Console patterns
- template-level diagnosis
- competitor context across many pages
- implementation prioritization across the wider site
That is why I use a checker for triage, then widen the work only if the page or pattern deserves it.
When the problem is no longer page-level
Stop treating it like a one-page issue when:
- several pages show the same failure
- Search Console shows recurring indexation problems
- the site changed recently
- a migration or redesign introduced signal conflicts
- the right page is still losing after the obvious fixes
That is when a broader technical SEO audit service or technical SEO consulting becomes more useful than repeated one-page cleanup.
If the drop followed a release, read the website migration SEO checklist as well.
For an example of the output a competitive audit should produce, see the GetResponse competitive SEO audit work sample. It shows the difference between collecting issues and turning them into a prioritized plan. If the same problem is repeating across important pages, contact me about a focused site review.
What I would not overreact to
These are common distractions:
A slightly short paragraph
Not every page needs more text.
A score that looks dramatic
The score matters less than the blocker behind it.
Missing schema on a weak page
If the page is still unclear or unconvincing, schema is not the first move.
Tiny optimization tasks before the main issue is solved
The queue matters more than the total issue count.
The practical takeaway
A website SEO check is useful when it helps you separate the real problem from the long list of possible ones.
Start with eligibility. Then check targeting. Then read the page like a buyer. Then check internal support. Only after that should smaller markup details get much attention. That order is how you stop an audit from turning into busywork.
FAQs
What is the first thing to check on a website for SEO?
Check whether the final page is eligible to rank: response status, redirects, noindex, and canonical ownership. If those are wrong, the rest matters less.
Can I check a website for SEO issues without paid tools?
Yes. You can get a useful first pass from a focused free checker, manual page review, Search Console, and a direct comparison with the current results for the target query.
Should I check the whole site or one page first?
Start with one important page. If that page shows a pattern that likely affects a wider template or section, then expand the audit.
Is a website SEO checker enough on its own?
No. It is useful for first-pass diagnosis, but it does not replace broader technical review, Search Console analysis, or competitor context when the issue spans several pages.
