You know what you don't know, and you don't know what you don't know about SEO—programmatic SEO especially.

This knowledge gap is the foundation of most agency dysfunction. SEO is technical enough that clients can't easily evaluate the work. Is that technical audit comprehensive or surface-level? Is that content strategy smart or generic? Is that link building campaign legitimate or risky? Unless you've spent years in SEO, you genuinely can't tell.

All agencies use asymmetric information to their advantage to hide things from clients, including measuring inputs and outputs. Bad agencies exploit this gap deliberately. They deliver impressive-looking reports full of metrics that don't matter. They create busywork that looks productive but doesn't move rankings. They blame algorithm updates for their own failures. They use jargon to obscure simple concepts and make you dependent on their 'expertise'. Even decent agencies often fail to close this gap. 

The result: you're paying for work you can't evaluate, delivered by people who have no incentive to make you smarter. 

The nature of SEO marketing is that it takes a minimum of 3+ months from the date of a solid SEO deployment campaign before you see any results. Most often it's 4-6 months.

That's a very long feedback loop. Many agencies use this as an advantage to skim your money over time while delivering little or nothing.

Here's how this works: an agency signs you up, collects your first 1-2 months of retainer, and does... something. Maybe some content. Maybe some technical fixes. Maybe just reports. By month three, when you start asking about results, they point to the long timeline: "SEO takes time, trust the process." By month four or five, if nothing has improved, they blame algorithm changes, your competitors, or "technical issues on your end." You've wasted time and money.

The long feedback loop makes accountability very hard. A bad paid ads campaign fails in a few weeks — you see poor performance and cut it. Bad SEO can hide for months, burning budget the entire time.

This isn't an argument against SEO — good SEO genuinely requires time. It's an argument for being careful about who you trust with that timeline. The agencies that exploit long feedback loops know you won't figure it out until it's too late.

SEO is a zero-sum game—it's an existing demand capture GTM play rather than generating new demand—there's conflicts of interest in servicing customers from the same market vertical and geography. While markets and the search economy are huge, there's inherent tension if you're servicing, e.g., two Canadian corporate law firms at the same time. 

If an agency is working with you and your competitor, every keyword you both want to rank for creates a conflict. Every strategic insight they develop could benefit either client. Every link opportunity, every content angle, every technical advantage—they're choosing who gets it. Even with the best intentions, they can't fully serve both interests.

Most agencies handle this by not handling it and not disclosing competing clients. They rationalize it in various ways, but SEO rankings are relative—for you to go up, someone else goes down.
