Our free SEO analyzer checks one page of a website in a few seconds and sorts what it finds into three groups: problems (red), points to improve (orange) and passed checks (green). This guide explains each line of the report, how serious it is, and the order in which to work through it.
Have the report open next to this article: run your page through the SEO analyzer, then download the PDF to share it with your team or your web agency.
Start with the problems (red)
Red lines are things that can stop a page from being indexed, understood or trusted. Fix them first, in this order.
“The page is excluded from Google (noindex)”
The page tells search engines not to index it. On a test site that is normal; on a live page you want to rank, it is the most serious problem possible, because the page will simply never appear. It often happens after a redesign, when the “discourage search engines” option is forgotten.
“Page not secure (HTTP)”
The page is not served over HTTPS. Browsers show a “not secure” warning, forms become risky and HTTPS is a ranking signal. Install an SSL certificate (most hosts include one; otherwise our free SSL certificate generator creates a Let’s Encrypt certificate) and redirect the whole site to HTTPS.
“Missing title tag”
The title is the clickable line in Google’s results. Without it, Google improvises, rarely well. Our guide to the title tag and meta description explains how to write a good one.
“Missing viewport tag”
Without it, phones display the page as a tiny desktop page. Google indexes the mobile version of websites, so this matters for rankings as well as for visitors.
“The canonical points elsewhere”
The canonical tag tells Google which address is the reference version of a page. If it points to another address, Google may index that one instead of the page you analysed. Sometimes that is intended (duplicates, filtered pages); often it is a template mistake copied across the site.
Then the points to improve (orange)
Title and description length
“Too long: it will be truncated” or “Very short”: the analyzer counts characters. As a guide, aim for about 50–60 characters for the title and 140–155 for the description, then check the real display width with our Google preview tool.
“Missing meta description”
It is not a ranking factor, but it is your sales pitch in the results. Without it, Google picks a snippet from the page, often an unhelpful one.
H1 headings and heading outline
A page should have one main H1 heading that says what it is about, then H2 and H3 sub-headings in order. “Some levels are skipped (e.g. H2 → H4)” is minor for Google but matters for accessibility and readability: keep a continuous hierarchy.
Images without alt attribute
The alt text describes an image for screen readers and for search engines. Describe every meaningful image; use an empty alt (alt="") for purely decorative ones.
No canonical tag
Not an error in itself, but declaring the reference address of each page avoids duplicate-content issues (with or without www, with tracking parameters, and so on).
Open Graph tags and structured data
Open Graph tags control how the page looks when shared on social networks and in messaging apps. Structured data (JSON-LD) helps Google understand who you are: at least Organization or LocalBusiness for a company website. Our Open Graph generator and structured data generator write the code for you.
Little text
“Little text: expand the content useful to visitors.” A page with only a few dozen words gives Google little to understand and visitors little to act on. Answer the questions your customers really ask.
Declared language
The lang attribute on the html tag tells browsers and search engines which language the page is in. It is quick to fix and helps with multilingual websites.
The mobile speed score
The report also shows a mobile speed score out of 100, taken from Google’s PageSpeed Insights. 90 and above is good, 50–89 needs work, below 50 is slow. A slow page loses visitors before they read anything. For the details behind the score, run the page through our website speed test and read our guide to Core Web Vitals.
The analyzer also reports the server response time: if the server itself is slow to answer, every page is slow, whatever you optimise. Hosting and caching are usually the cause.
The passed checks (green)
Green lines are what already works: HTTPS, an indexable page, a title of the right length, one H1, and so on. They are worth reading too, because they show you what to keep when you change the page.
A suggested order of work
- Indexing and security: noindex, HTTPS, canonical.
- Mobile: viewport, then speed.
- The search result: title and description.
- Structure and content: H1, headings, text, images.
- Extras: Open Graph, structured data, language.
Then run the analyzer again: the report should turn greener with each pass.
What the analyzer does not tell you
The analyzer checks one page, automatically. It does not look at your whole website, your competitors, the links pointing to you, or whether your content matches what people search for. Those are what decide rankings in the long run. For that, the report offers a free full audit by our team (the “Get the full audit free” button pre-fills the request with the issues found).
Frequently asked questions
My page is all green: will it rank first?
Not necessarily. The analyzer checks technical basics. Rankings also depend on content quality, competition, links and how well the page answers the search.
Why does the analyzer refuse some websites?
It only checks public websites, respects their robots.txt (it identifies itself as ITLabsProBot) and gives up on pages that take too long to answer or are not HTML.
Can I analyse my competitors’ pages?
Yes, any public page. Comparing their report with yours is a good way to spot quick wins.
In short
Fix the red lines first (indexing, HTTPS, title, mobile, canonical), then the orange ones (lengths, headings, images, structured data), keep what is green, and re-run the analysis after each round of changes. For a complete, human review of your website, discover our SEO services.
