Most pages that never show up in Google aren't victims of some complex algorithm; they're victims of skipping a few simple basics: a title with no keyword, an image that's three megabytes, a page nothing else on the site links to. This 15-point checklist is exactly what the RGB team runs through before publishing every page: simple, actionable, and free of confusing jargon.
What Is On-Page SEO and Why Does It Matter?
On-page SEO is the set of optimizations you make within the page itself: from the title and text structure to speed and structured data. Its big advantage is that, unlike off-page link building, it's 100% under your control. We cover where on-page SEO fits into the bigger picture in the complete guide to website SEO; here, we go straight to execution.
Part One: Content and Keywords (8 Items)
1. Identify search intent. Before writing, search that exact phrase on Google; if the results are all product pages and you're writing an article, you've entered the wrong race. Keyword research makes exactly this call data-driven, before you write a word.
2. One primary keyword per page. Two pages targeting the same goal become competitors, and Google won't take either one seriously. If you're unsure what keyword a page is actually focused on, RGB's free SEO tools help make that clear.
3. Title tag: around 60 characters, keyword close to the start, and a clear promise that earns the click.
4. Meta description: not a direct ranking factor, but it moves the click-through rate; 150 to 160 characters with a clear invitation.
5. One unique H1 and an orderly H2/H3 hierarchy: a proper heading structure helps both the reader and the crawler.
6. Short, descriptive URL: preferably in English, no dates or filler words, an address that still holds up next year.
7. A first paragraph that settles the matter: the reader should know within the first few lines that this page answers their question.
8. Purposeful internal links: link to your own related pages with meaningful anchor text, not "click here."
Part Two: Technical Page Factors (7 Items)
9. Speed and Core Web Vitals: a slow page loses both the user and the ranking. We simplify Google's three critical metrics in the Core Web Vitals guide.
10. Flawless mobile rendering: Google indexes your site's mobile version, not the desktop one.
11. Compressed images with alt text: a modern format like WebP and a short description for every image.
12. Structured data (schema): helps Google understand your content type and display a richer result.
13. HTTPS and baseline security: a "not secure" browser warning means the visitor leaves before ever seeing your content; check your status on the website security page.
14. Canonical tags and indexability: make sure the page isn't set to noindex and that the canonical URL is set correctly.
15. Content freshness: update important pages periodically; abandoned content gradually loses its authority.
"On-page SEO means respecting the user and the crawler at the same time; whenever you're torn between the two, side with the user."
