What to look for in an SEO agency (before you sign)

SEO is the easiest service to overpromise and the hardest to audit. Use this framework to tell real strategy from empty guarantees.

SEO has a reputation problem because it's opaque: results take months, tactics are technical, and anyone can claim to be an expert. This guide gives you the questions and evidence that separate an agency that grows your search presence from one that bills you for reports you don't understand.

Beware anyone who guarantees rankings

No one controls search engines, so no one can guarantee a specific rank by a specific date. A trustworthy agency guarantees a process — technical fixes, content, and authority building — and reports on leading indicators like crawl health, keyword coverage, and qualified traffic. If the pitch leads with 'page one guaranteed,' that's a signal to walk away.

Ask what they'll change on your site in the first 90 days

Good SEO starts with your own site. In the first quarter you should expect a technical audit, fixes to things blocking crawlers, improved on-page targeting, and a content plan. If the first deliverable is 'we'll build you 50 backlinks,' the priorities are backwards — links without a sound site to land on don't compound.

Make sure they report on revenue, not vanity metrics

Impressions and keyword counts are easy to inflate and hard to tie to business outcomes. Ask how they connect search work to leads, calls, and sales. The right agency sets up tracking that attributes results to specific pages and queries, then reports on the metrics that pay your bills.

Understand their link and content approach

How an agency builds authority matters more than how much. Ask where their links come from and whether content is written for humans or stuffed for bots. Tactics that worked a decade ago — link farms, spun articles, keyword stuffing — now actively harm you. A modern partner earns authority through genuine content and real relationships.

Check that they work in your industry's search landscape

Local service businesses, e-commerce, and national brands each have different search dynamics. An agency that wins in one doesn't automatically win in another. Ask for examples in your space and how they'd approach your specific competitive landscape.

Questions to ask any SEO agency

What will you change on my site in the first 90 days?
How do you tie search work to leads and revenue — not just traffic?
Where do your links come from, and can you show examples?
What does your reporting look like, and how often will I get it?
Can you share results from a business like mine?
What happens if rankings don't improve — what's your response?

Book the call

How long does SEO take to show results?

Most sites see meaningful movement in 3–6 months, with compounding gains after that. Anyone promising results in weeks is either lying or using tactics that put your site at risk.

Do I still need SEO if I run paid ads?

Yes. Paid ads stop the moment you stop paying; SEO builds an asset that keeps producing. The two work best together — paid for now, SEO for the next two years.

What's the difference between local and national SEO?

Local SEO targets customers in a geographic area and leans on your Google Business Profile and map presence. National SEO competes for broader queries without a location modifier. The tactics, timeline, and budget differ significantly.
