What is On-page SEO?
SEO can be divided into three main areas: technical SEO (speed, structure), on-page SEO (the content itself and the page's structure), and off-page SEO (external links). Of these, on-page SEO is what you can completely control yourself.
And good news: this accounts for 70% of your SEO success. If your on-page is done well, no magic is needed.
The 8 On-page Elements That Matter
1. Title Tag
The blue link in Google's search results. 50-60 characters, keyword at the beginning, brand name at the end.
Bad: Homepage | Somos Media Good: Professional Website Design, Somos Media
2. Meta Description
The short description below the title. 150-160 characters, encourages visitors to click. It's not a direct ranking factor, but CTR (Click-Through Rate) is.
3. H1 Main Heading
One H1 per page, which clearly describes what the content is about. It should contain the main keyword.
4. Heading Hierarchy (H2, H3, H4)
Logical structure. H2 for main sections, H3 for subsections. Don't skip levels (don't jump from H1 to H4).
5. URL Structure
Short, descriptive URL. /seo-guide/ is much better than /?p=4837.
6. Internal Links
From every new article, link to 2-5 older articles, and vice versa. This helps Google understand your site's structure and guides visitors deeper into your content.
7. Image Alt Text
Every image should have descriptive alt text. No need to stuff it with keywords, just describe what's in the image naturally.
8. Content Quality
Most important: does it truly answer the visitor's question? Is it longer than the competition, but not just word salad? Does it contain fresh data?
The Rule of Keyword Placement in 2026
In the past: "Stuff the text with keywords."
Today: Google understands synonyms and semantic fields. If your topic is "weboldal készítés", Google considers "honlap készítés", "web design", "site building" to be the same.
Rule: write naturally for humans, and the keywords will automatically be where they need to be.
