Organic search and market share
Organic search remains the single largest source of traffic for most websites. Even with the rise of paid ads and AI-generated answers, traditional organic results dominate click volumes. Understanding the market shares of different search engines and channels is the foundation of any SEO strategy.
- Google holds a global market share of 91.2% of all searches, according to Statcounter data (StatCounter, 2026).
- Organic search drives an average of 53% of all website traffic, based on analysis of over 3,500 websites (BrightEdge, 2025).
- The first organic search result has an average click-through rate (CTR) of 27.6%, according to CTR studies from the search industry (Backlinko, 2025).
- Page 1 results in Google receive 91.5% of all organic traffic — less than 1% of users click through to page 2 (Sistrix, 2025).
- Bing has increased its market share to 4.1% globally, partly driven by the Copilot integration in Windows (StatCounter, 2026).

- In the Nordics, Google is used by over 94% of the population as their primary search engine (StatCounter, 2026).
Search behavior and user data
How users search — what devices they use, how long their queries are, and what they do after searching — directly impacts which SEO strategy delivers results. Mobile search has long surpassed desktop, and voice search continues to grow steadily. Here are the key numbers for search behavior in 2026.
- 63% of all organic Google traffic now comes from mobile devices, based on global traffic data (Semrush, 2025).
- The average search query is 3.2 words long. Long-tail searches (4+ words) account for 70% of all searches (Ahrefs, 2025).
- 46% of all Google searches have local intent — the user is looking for something nearby (Google, 2025).
- Voice search accounts for an estimated 21% of mobile searches, with an average phrase length of 6.5 words (Statista, 2025).
- The average time spent on a page from organic search is 2 minutes and 17 seconds (Semrush, 2026).

- 82% of smartphone users perform a "near me" search at least once a week (Google, 2025).
Technical SEO and page speed
Technical performance is a prerequisite for visibility. Google uses Core Web Vitals as a ranking factor, and users abandon slow-loading pages. Investment in technical SEO has a direct effect on both rankings and conversion rates.
- Websites that pass all three Core Web Vitals have 24% lower bounce rates than those that don’t (Google Chrome UX Report, 2025).
- Improving load time from 3 to 1 second increases conversion rates by an average of 32%, according to performance analyses (Portent, 2025).
- Only 38% of websites meet all Core Web Vitals requirements for mobile, based on Chrome UX Report data (Google Chrome UX Report, 2026).

- Crawl errors reduce indexation by up to 47% — regular technical audits are critical (Ahrefs, 2025).
- Pages with over 3 seconds of load time have 53% higher bounce rates on mobile (Google, 2025).
- Implementing schema markup increases the chance of rich snippets by 58%, which can boost CTR by 20–30% (Search Engine Journal, 2025).
Content strategy and blogging
Content is the fuel of SEO. But not all content performs equally — length, format, publishing frequency, and update strategy all have measurable effects on organic visibility. These numbers show what actually drives results in content marketing.
- The average word count for content ranking on page 1 of Google is 1,447 words, based on analysis of 10,000 search results (Backlinko, 2025).

Link building and authority
Backlinks remain one of Google’s strongest ranking signals. See our link building strategy guide for techniques. The quality and relevance of your link profile directly impacts how well you rank in competitive niches. Here are the key numbers for link building in 2026.

Local SEO
For businesses with a physical presence, local SEO is critical. Google Business Profile, local search results, and the map pack are often where the customer makes their choice. Local SEO has a direct line to revenue that is hard to beat.
