Questions to ask any agency

  • What exactly will you do each month?
  • How will I know it's working, in leads and revenue, not just rankings?
  • Who owns my website, domain and Google Business Profile?
  • What happens if I cancel?
  • What's included, and what costs extra?

Red flags

  • Guaranteed #1 rankings. Google controls rankings and says no one can guarantee them.
  • Secret methods they won't explain at all
  • Buying links, fake reviews or keyword-stuffed business names
  • Owning your accounts, or charging to hand them back
  • Reports full of numbers with no connection to leads or revenue
  • Long lock-in contracts with no clear deliverables

What good reporting looks like

  • Where you show up in search, Maps and AI assistants, and how it's changing
  • How many leads came in, and from where
  • Which leads became customers, and what they were worth
  • What was done this month, and what's next

Check the fit

Ask whether they work with businesses like yours and how they'd approach your market. They should understand how your customers search and what a lead is worth to you.

Questions

How long should I give an SEO agency to show results?+

Expect early signs within two to three months and clearer results in four to six. If nothing has improved and nobody can explain why after six months, ask hard questions.

Should I sign a long-term SEO contract?+

Month-to-month or short terms keep an agency accountable. If you sign longer, get deliverables and cancellation terms in writing.

Is it a red flag if an agency guarantees rankings?+

Yes. Google states that no one can guarantee a #1 ranking. Agencies can promise work, transparency and reporting, not positions.
