The On-Page SEO Checklist: What to Check on Every Page of Your Website

An on-page SEO checklist you can actually use: title tags, meta descriptions, headings, links and images, rated MOT style with a free audit tool.



An on-page SEO checklist covers the things you control directly on each page: the title tag, meta description, headings, internal links, images and the content itself. Work through it and Google can see the changes within days, not months.

Most of SEO involves waiting. Waiting for links, waiting for authority, waiting for Google to notice you exist. On-page SEO is the glorious exception. You make a change today and Google can see it this week. No mysteries, no crossed fingers.

So we have turned it into something every UK business owner understands: an MOT. Seven checks, each one a pass, an advisory or a fail. Grab a page of your website and score along at home.

What is on-page SEO?

On-page SEO is everything you do on the page itself to help it rank: how it is titled, structured, written and linked. It is the half of SEO with no waiting room.

The other parts of the job, technical SEO and link building, depend on other people and other machines.

On-page is just you, your website and an honest hour of checking. Which is exactly why it gets skipped. Nothing that sits quietly under your nose ever feels urgent, and then one day you search for your own product and find page two staring back.

What is on the on-page SEO checklist?

Seven checks: title tag, meta description, headings, internal links, image alt text, content depth, and page speed. Here is the MOT card:

More than three fails and we should probably talk. More than five and, well, the good news is there is nowhere to go but up.

How do you write title tags and meta descriptions that earn clicks?

Treat them as your shop window: the title makes a promise in under 60 characters, and the meta description backs it up in under 160.

The title tag is what shows as the blue link in Google. One keyword, placed naturally, then a reason to care. "Sash Window Repair in Harrogate: Prices and Timescales" beats "Services - Smith Joinery" every single day of the week.

The meta description is the small print underneath, and Google says it does not use it for ranking. It absolutely uses it for clicks though, because humans read it while deciding where to go.

Google's own documentation tells you to write one unique description per page, and for once the official advice is also the profitable advice. We find that pleasing, like when the healthy option turns out to be chips.

Why do internal links and alt text matter?

Internal links show Google how your site fits together and pass authority between your pages. Alt text tells Google what your images show, because it still cannot really look at pictures.

Every page on your site should link to at least two other relevant pages. Not because a checklist says so, but because a visitor who finishes reading should always have somewhere useful to go next.

Google follows those same paths, and pages nothing links to are pages Google assumes nobody cares about.

Alt text started as an accessibility feature and still is one, which is reason enough to do it properly. The bonus is that Google reads it too. Describe what is in the image in a plain sentence. Your screen reader users, and your rankings, both say thank you.

How does content depth affect rankings?

Google ranks pages that answer the question properly, not pages that hit a word count. Depth means covering what the reader actually came to find out.

A thin page is not rescued by stuffing keywords into it, and a long page is not automatically deep. The test is brutally simple: would a real customer finish the page with their question answered?

Every blog we publish goes through our lead writer's edit before it goes anywhere near the internet, precisely because "does this actually answer the question" is a check machines still get wrong. If writing is the bit you dread, that is quite literally what our copywriting service is for.

What happens when you get the basics right?

The boring basics compound. Calder Windows saw a 99 per cent organic traffic uplift, and Stump Cross Caverns grew organic traffic 93 per cent in a year. Not bad for a hole in the ground.

Neither of those came from a secret trick. They came from pages that pass the MOT, published consistently, on sites Google can trust. That steady, checkable work is the whole philosophy behind Hero+, and it is why our SEO service treats on-page as a habit rather than a launch-day task.
