Grey Hat SEO
SEO practices that aren't explicitly banned by Google but push the boundaries of their guidelines. The tactics agencies won't talk about publicly but use behind closed doors. Today's grey hat is often tomorrow's black hat.
Why It Matters
Most real-world SEO doesn't fit neatly into white hat or black hat. Grey hat is the vast middle ground - tactics that technically don't violate Google's guidelines (or exploit ambiguity in them) but wouldn't survive scrutiny if Google looked closely.
The problem with grey hat is that the line keeps moving. Guest posting for links was standard practice until Google started cracking down on scaled guest post networks. Tiered link building, aggressive anchor text ratios, and AI-generated content with light editing all live in grey hat territory today. Any of them could become explicitly penalised tomorrow.
Understanding grey hat matters because you need to make informed risk decisions. Pretending everything is either perfectly safe or obviously dangerous ignores the reality of competitive SEO.
In Practice
Common grey hat tactics include: buying expired domains for their backlink profiles, building links through niche edits (adding your link to existing content on other sites), using AI to generate content drafts that get human editing, and aggressively pursuing link exchanges through intermediaries.
The risk calculation depends on your situation. A brand-new affiliate site with nothing to lose has a different risk tolerance than an established business with years of organic traffic. Grey hat can accelerate growth, but it creates technical debt - if Google updates its guidelines, you're exposed.
If you choose grey hat tactics, go in with eyes open. Know the risk. Have a contingency plan. And never let an agency use grey hat tactics on your site without your explicit knowledge and consent - it's your domain on the line, not theirs.
Common Mistakes
Thinking grey hat is safe because it's not black hat. Not tracking which tactics you're using so you can't diagnose issues when an algorithm update hits. Letting agencies use grey hat without disclosure - you should always know what's being done to your site. Assuming a tactic is still grey hat just because it worked last year.
