Does the best SEO agency for a small business differ from one for a national brand?
The fundamentals are identical — technical health, useful content, authority, AI visibility. What changes is emphasis: a single-location business lives and dies on local signals and reviews, while a national brand competes on content depth and site architecture. Pick an agency that can show work at your scale.
What access should I give an SEO agency?
Editor-level CMS access, Google Search Console, Google Business Profile (if local), and analytics. Keep billing and domain registrar access yourself. A legitimate agency never needs your registrar login.
What does month one with a good agency look like?
Mostly audit and foundation: technical crawl, keyword and AI-prompt research, quick technical fixes, and a prioritized roadmap. If month one is a stack of new blog posts with no audit, the engagement started backwards.
A 10-minute vetting call: exactly what to ask
You can disqualify most weak agencies in one call. Ask these five questions and listen for the shape of the answer, not the polish.
- “Walk me through a campaign that didn’t work.” Good agencies have one ready and explain what they changed. Evasion is a red flag.
- “Who does the actual work on my account?” You want named roles, not “our team.” Ask how much is subcontracted.
- “What do you need from us to succeed?” Real SEO requires your input: subject-matter review, site access, approvals. “Nothing, we handle it all” usually means thin templated work.
- “How will you handle AI search?” Listen for specifics: structured data, citable answer-first content, entity consistency, AI Overview tracking. Buzzwords without mechanics are a pass.
- “What happens to the work if we leave?” You should own the site, the content, the analytics, and every account. Anything held hostage is a dealbreaker.
Green flags: they ask about your margins and capacity before promising volume. Red flags: guaranteed rankings, secret methods, or a price before they’ve seen your site.
