SEO agencies.

SEO is the discipline of earning the right traffic from Google for free, plus - increasingly in 2026 - being chosen, cited, and summarised by AI answer engines like ChatGPT, Perplexity, and Google's AI Overviews. Done well it compounds. Done poorly it's expensive theatre.

Editor's note
The UK has roughly 476 agencies that put SEO at the top of their service list. They split into three buckets: boutique consultants and small specialist shops charging £500-3,000 a month; mid-market agencies running fuller programmes at £1,500-7,500; and network or holding-group agencies billing £7,500-20,000 and up for enterprise work. In 2026 the discipline has expanded. Traditional ranking optimisation still matters - Google Search Central is clear that crawlability, helpful content, and trust signals carry the same weight as they always did. But visibility now also means being cited in AI Overviews and surfaced by ChatGPT and Perplexity. Most credible UK agencies are quietly absorbing this as Generative Engine Optimization (GEO) without making it a separate service line. A few are loud about it. Watch for which.

Red flags
5 to watch
in any pitch
  • · Guaranteed rankings or 'top 3 in 30 days' promises
  • · Pure performance-based pricing (misaligns incentives)
  • · Aggressive link building or 'private networks' (PBNs)
  • · Vague reporting that won't connect to revenue
  • · No request for Search Console + analytics access

What brands ask about seo agencies.

5 questions our editors get most often, answered honestly. No agency-marketing speak.

Curated by humans

UK SEO retainers in 2026 split into three tiers: boutique consultants and small specialist shops run £500-3,000 a month, mid-market agencies £1,500-7,500, and network or holding-group shops £7,500-20,000+. One-off audits land between £1,500 and £10,000 depending on site complexity. Pure performance-based pricing exists but tends to misalign incentives - Google Search Central itself warns against providers leaning on guarantees rather than process.
