Frequently asked

What brands ask about seo agencies.

The 5 questions our editors get most often, answered honestly. These apply to seo as a discipline across every industry.

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.
