Good SEO partners exist, and so do expensive ones that deliver nothing. Here are seven warning signs, the questions that expose them, and what a healthy agency relationship looks like.
Hiring an SEO provider is hard because you're buying something you can't easily judge. That asymmetry is where bad actors thrive, and where honest agencies get lumped in with them. These seven signs help you tell them apart.
TL;DR: Be wary of guaranteed rankings, secret "proprietary" methods, link packages, reports built on vanity metrics, refusal to give you account access, long lock-in contracts, and mass-produced AI content. Google's own guidance on choosing an SEO professional warns that no one can guarantee a top ranking. A trustworthy partner starts with your business goals, explains what they're doing and why, and gives you ownership of everything they build.
Nobody controls Google's results, and Google says as much. A promise like "page one in 90 days" is either a very narrow claim or a sales line. Ask what exactly is guaranteed and what happens if it isn't delivered.
Real SEO work isn't mysterious. Fixing indexing, improving content, and earning mentions can be explained clearly. "Proprietary techniques we can't share" often hide cheap tactics. Compare their pitch against the myths we've covered.
A set number of links per month, from unnamed sites, usually means low-quality placements. Buying links to pass ranking signals violates Google's spam policies. See what links actually do.
Reports that celebrate Domain Authority, "health scores," or keyword counts without tying anything to leads or revenue are a warning. See Domain Authority and build reports around outcomes in a proper dashboard.
Your Search Console, Analytics, domain, and website should be in your name with you as owner. If an agency insists on holding them, leaving becomes expensive.
Twelve-month lock-ins with heavy penalties benefit the agency. SEO takes time, but a confident provider doesn't need to trap you. Be sure they explain realistic timelines, as we discuss in why "six months" is mostly made up.
Dozens of generic AI articles a month is the volume trap. It conflicts with Google's guidance on scaled content, as explained in Does Google penalize AI content? and the volume myth.
Are all SEO agencies untrustworthy? No. Many do excellent work. These signs help you find them.
Should I do SEO in-house instead? It depends on budget and skill. Many businesses use a hybrid approach.
How much should SEO cost? It varies widely. Evaluate the plan and expected value, not just the price.
What if I'm already locked in with a bad agency? Review your contract, secure your account access, and document the work delivered so far before deciding.
