How to do grey hat SEO

Grey hat SEO sits between accepted best practices and tactics that violate search engine guidelines. The core approach involves techniques that aren't explicitly forbidden but operate in ethically questionable territory—they work until search engines decide to penalize them, which creates real business risk for your clients.

Common grey hat tactics include private blog networks (PBNs), where you build a network of aged domains with existing authority to link back to client sites. You'd purchase expired domains with decent backlink profiles, rebuild them with thin content, and use them exclusively to pass link juice to money sites. Related to this is tiered link building, where you create links to your link sources rather than directly to the client site, attempting to obscure the artificial linking pattern. Schema markup manipulation falls into this category too—marking up content in ways that technically follow markup standards but are designed to game rich snippets or featured snippets rather than genuinely describe the content. You might also see bulk footer link exchanges, where agencies trade links across multiple client sites en masse, or aggressive keyword stuffing in less visible areas like image alt text and meta descriptions. Some practitioners buy expired domains with rankings and redirect them to client sites, leveraging the domain's existing authority while the redirect passes value.

The problem with grey hat work is that it relies on search engines not paying attention or not caring enough to update their algorithms. When Google or other engines do notice these patterns—which they increasingly do—the penalties are substantial. You're explaining to a client why their site dropped 40 rankings because the link network got discovered, or why their rich snippets were removed for schema manipulation. Your agency's reputation suffers when these tactics fail, and clients remember the drop far longer than they remember any temporary gains.

If you want to take calculated risks, focus on tactics closer to white hat: testing edge cases within Google's actual guidelines, aggressive content marketing to natural link acquisition, or strategic paid promotion that doesn't violate rules. The sustainable play is building a reputation that clients trust to deliver predictable results, not one-off wins that crater their visibility. Grey hat tactics might work for a few months or even a year, but they're increasingly expensive insurance policies against algorithm updates that are becoming more sophisticated at pattern detection.
