What to ask when choosing an SEO agency

The agencies in this list use similar service names. The difference usually comes out in the questions you ask at the first meeting.

• What will the report include? Ask which metrics (clicks, impressions, conversions, AI visibility) they will report, how often and with which tool. A report that only lists rankings does not show the commercial impact of the work.
• Who will implement the work? Some agencies make technical changes themselves. Others write a brief and expect your development team to implement it. Agree early on which suits you. Also discuss who will have access to which accounts.
• How deep does the technical SEO go? Ask to see a sample report showing how the audit handles crawling, indexing, canonicals, hreflang, Core Web Vitals and structured data. If you are planning a site migration, ask who will prepare the redirect map.
• Is there a ranking guarantee? Google advises anyone hiring an SEO to be wary of promises that guarantee rankings. Several agencies in this list say the same on their own pages. It is healthier to ask for measurable goals and a realistic timeline.
• How is link building done? Ask where links come from, how they are earned and whether paid link packages are used. An agency that can explain methods such as digital PR and content promotion carries less risk.
• How do they measure AI search? Ask agencies that say they offer GEO how they measure the way your brand appears in ChatGPT or Gemini. To see where you stand, you can use our free AI visibility check.
