Quick quiz

Is SEO right for you, and how should you start?

Question 1 of 425%

Do people search Google for what you sell?

Yes, I think soNo, it is new or very nicheI don't know

The distinction between on-page vs off-page SEO is useful because it separates what you can change today from what you must earn. Both matter: a great page with no links struggles in competitive markets, and strong links cannot save a page that does not answer the query. This guide lists the factors of each, adds technical SEO, and gives an order of priority. Definitions: on-page SEO, off-page SEO and technical SEO.

What is the difference between on-page and off-page SEO?

What are the on-page SEO factors?

• Content that answers the query better than current results, with a direct answer first.
• Title tag and meta description that match the intent and invite the click.
• Headings: one H1, logical H2 and H3, phrased as questions when natural (see HTML tags for SEO).
• Internal links with descriptive anchors to and from related pages.
• Images compressed, with alt text.
• Structured data consistent with the visible content.
• Experience signals: author, sources, dates, original information.

Google's SEO Starter Guide covers most of these. The free on-page audit checks a page in seconds.

What are the off-page SEO factors?

• Backlinks from relevant, trusted sites, the strongest off-page signal (see how to get backlinks).
• Brand mentions in media, comparisons and forums, linked or not.
• Reviews on Google and industry platforms, especially for local businesses.
• Digital PR: studies, expert comments and stories journalists cite (see digital PR).
• Presence on the sources AI assistants read, which now shapes recommendations in ChatGPT or Gemini.

Which is more important: on-page or off-page SEO?

It depends on competition. In a niche with few strong competitors, excellent on-page content often ranks with modest links. In competitive markets, pages of similar quality are separated by authority, and off-page work makes the difference. In every case, on-page comes first: links pointing to a weak page are wasted.

In what order should you work?

1. Technical basics: indexing, speed, mobile, no blocking errors; Google's Search Essentials list the minimum requirements.
2. On-page: one strong page per intent, well structured and linked.
3. Off-page: links and mentions from relevant sites, steadily.
4. Measure and repeat: improve pages that rank 8 to 20, earn links to your most important pages.

On-page, off-page and AI visibility

AI assistants use both sides: on-page clarity decides whether a passage can be quoted, and off-page reputation decides whether a brand is trusted enough to recommend. See GEO vs SEO and brand authority.
