How should a business choose an SEO agency?

Direct answer

Choose an SEO agency by whether it can diagnose the specific visibility problem before prescribing work. A credible evaluation separates crawlability, indexation, query relevance, local visibility, competing pages, content quality, authority signals and conversion measurement. The agency should explain what evidence supports each recommendation and should not guarantee a ranking position it cannot control.

Signals worth investigating

• The proposal begins with a fixed monthly package before the agency identifies the visibility problem.
• Keyword lists are presented without explaining search intent, landing-page fit or evidence quality.
• Indexation is treated as equivalent to ranking or traffic.
• New pages are recommended without checking for existing pages that already serve the same intent.
• Reporting focuses on rankings or traffic without connecting search activity to useful business actions.

A better diagnostic sequence

1. Verify technical crawlability and indexability before assuming the problem is content or authority.
2. Pair important queries with the page that should satisfy each intent.
3. Check whether multiple pages compete for the same decision and whether important intents have no suitable page.
4. Compare the evidence, structure and usefulness of competing search results rather than copying their word counts.
5. Track impressions, clicks, landing-page engagement and qualified conversions after controlled changes.

Decision criteria

• Technical search diagnosis
• Query-to-page intent mapping
• Cannibalization and content-gap control
• Evidence quality and competitor analysis
• Internal linking and information architecture
• Measurement of search movement and conversions
• Transparency about uncertainty and ranking limitations

Questions worth asking before you buy

• What evidence shows where our search visibility is failing?
• Which existing page should rank for each priority query?
• How will you prevent new pages from competing with our current pages?
• What changes will be measured before and after implementation?
• How will search performance connect to enquiries, sales or other business outcomes?

Methodology and evidence limits

DSDillon separates measured first-party search observations, observed public result evidence and modelled opportunity. None of those evidence classes is treated as a guarantee of future ranking.
