There are four main types of SEO: on-page SEO (optimising your content), off-page SEO (building authority and links), technical SEO (your site's foundation and crawlability), and local SEO (ranking for near-me searches). A site that is strong in one but weak in another rarely ranks for competitive terms - the four work together. Here is what each covers. For the basics first, see what SEO is.
| Type of SEO | What it covers | Key elements |
|---|---|---|
| On-page SEO | The content on each page | Keywords, titles, headings, internal links |
| Off-page SEO | Authority built off your site | Backlinks, mentions, reviews, PR |
| Technical SEO | The site foundation | Speed, mobile, indexing, schema, structure |
| Local SEO | Near-me and map searches | Google Business Profile, citations, reviews |
1. On-page SEO
On-page SEO is everything you optimise on the page itself - targeting the right keyword, writing helpful content, and structuring titles, headings, URLs and internal links so both people and Google understand it. It is where most rankings are won or lost. Full checklist in our on-page SEO guide.
2. Off-page SEO
Off-page SEO builds your site's authority and trust through signals from outside your site - mainly backlinks from other reputable sites, plus brand mentions, reviews and digital PR. It is how you earn the credibility to outrank competitors. See our off-page SEO guide.
3. Technical SEO
Technical SEO makes your site easy for Google to crawl, index and trust - covering speed, mobile-friendliness, site structure, HTTPS, structured data and more. Without it, even great content struggles. See our technical SEO checklist.
4. Local SEO
Local SEO wins near-me and Google Map searches - vital for any business serving a city or catchment. It centres on your Google Business Profile, local citations, reviews and location pages. See our Local SEO services.

Why you need all four
Think of it this way: technical SEO lets Google read your site, on-page makes each page relevant, off-page gives you the authority to compete, and local wins nearby customers. Skip one and the others underperform. A complete SEO program balances all four. To see where your site is weakest, start with a free SEO audit.
