On-Page SEO Basics

On-page SEO is everything you can change on the page itself. No outreach, no budget, no waiting for another site to notice you. You edit the page and you are done. It is where anyone should start, because it is the only part of SEO that is entirely yours.

What counts as on-page

The boundary is simple. If you can fix it by editing your own page, it is on-page. If it depends on somebody else's website, it is off-page. If it is about whether Google can reach and process the page at all, it is technical.

So on-page covers the words on the page, the title it carries, how it is structured, the images in it, and the links from it to your other pages. A bakery writing a page about sourdough controls every one of those before anyone else on the web has an opinion about it.

What it does not cover is the thing beginners assume it is: putting a keyword in as many places as possible. Google has not worked that way for a very long time, and a page written to hit a keyword count reads exactly like what it is.

The five things that matter, and where each is explained

This section breaks into five topics. Read them in this order: each one assumes the previous.

• Keywords and search intent: the words people type, and what they were actually hoping to find. Getting the intent wrong makes everything downstream pointless, which is why it comes first.
• Titles and meta descriptions: the only part of your page most people ever see, because they see it in the results before deciding whether to click.
• Content that deserves to rank: Google publishes a specific test for this, built around who wrote the page, how, and why it exists.
• Images and alt text: the part of a page a search engine cannot read, and the part blind visitors depend on you describing.
• Internal linking: the links between your own pages, which decide which of them get found at all.

One thing worth settling before you start, because it is repeated everywhere as a rule: Google publishes no character limit for a title or a meta description. The familiar "around 155 characters" is where a result tends to get visually cut off on a particular screen, not a limit anyone enforces. Write the clearest version, not the longest one that fits.

What to do first

• Pick your most important page and read it as a stranger who searched for it. Does the first paragraph answer what they came for?
• Check that the page has a unique title that describes it, not your business name repeated.
• Break long pages up with real headings, so a reader can scan and find their part.
• Link the page to and from the other pages it relates to.
• Add alt text to any image that carries meaning.

That is a morning's work on a small site, it needs no tools, and it is worth more than anything you could buy.
