Link Schemes to Avoid: Tactics That Put Your Site at Risk
A link scheme is a pattern, not a single link. One paid post on a relevant site rarely sinks anyone. What gets sites into trouble is repetition: the same type of link, from the same type of site, with the same anchor, over and over. Google's systems are designed to spot exactly those patterns. Below are the schemes that tend to leave the clearest footprints, why, and what people do instead.
Private blog networks
A PBN is a group of sites, usually built on expired domains with existing links, that one person or group controls and uses mainly to link to money sites. The pitch is control: you choose the anchor, the page and the timing.
Why it's risky: networks leave traces. Shared hosting, similar themes, the same plugins, identical author bios, cross-linking, registration patterns and sites with no real audience. Google has acted against networks repeatedly, and when a network is caught, every site it links to is exposed.
Lower-risk alternative: spend that budget on content placements and partnerships with sites you don't own, that have real readers in your niche.
Mass link exchanges
Swapping links with one related business is normal. Joining a group where dozens of sites cross-link, or creating a "partners" page with 80 unrelated links, is a scheme Google names explicitly in its link spam policies.
A common version in India: groups on messaging apps where site owners trade guest posts in rotation. Each swap looks ordinary. Hundreds of them across the same small pool of sites look like a network.
Lower-risk alternative: link to related businesses when it genuinely helps your readers, and don't make it conditional.
Paid followed links at scale
Buying a followed link is within Google's definition of link spam. In practice, the risk scales with how obvious the pattern is. A handful of paid guest posts on relevant sites with natural anchors leaves a light footprint. Hundreds of paid posts on general "write for us" blogs, all with exact-match anchors, leaves a heavy one.
Warning signs that a site sells links to anyone:
- A visible price list or "sponsored post" page with dofollow promised
- Recent posts covering unrelated topics: crypto, home loans, CBD, wedding photography
- Each post has one or two commercial outbound links and nothing else
- No real comments, social presence or readers
Lower-risk alternative: if you pay for placement, insist on relevance and real traffic, use branded or natural anchors, and understand the risk you're taking. Or treat it as advertising, accept a sponsored attribute, and value the traffic.
Automated link building
Software and services that blast links across forums, comments, profiles, wikis and bookmarking sites. They're cheap and fast. They're also the tactic Google's systems have had the longest practice ignoring.
Why it's risky: high volume, low quality, unnatural velocity and repetitive anchors. At best the links are ignored. At worst they add to a pattern that leads to a manual action.
Lower-risk alternative: if you use automation or bulk links at all, keep them far from your money pages. Many people who use them point them only at intermediate pages such as Web 2.0 properties or guest posts, with natural anchors and gradual pacing. That reduces, but does not remove, risk. The tiered link building risks article covers this honestly.
Keyword-rich footer and widget links
Theme designers, web agencies and widget makers sometimes embed a keyword link in every site that uses their work: "Best SEO company in Noida" in a client's footer, for example. Spread across hundreds of sites, those links look manipulative.
Lower-risk alternative: use your brand name as the anchor and add nofollow, or remove the credit entirely and ask happy clients for a case study or testimonial link instead.
Expired domain redirects
Buying expired domains that have strong backlinks and 301-redirecting them to your site, to inherit their link value. Google's spam policies cover expired domain abuse, and redirects from unrelated domains are increasingly likely to be discounted.
Lower-risk alternative: buy an expired domain only if it's genuinely related to your business, such as a competitor that closed down, and you're continuing its purpose.
Low-quality directories and article sites
Bulk submissions to hundreds of generic directories and article sites. Google names low-quality directory and bookmark links in its policy.
Lower-risk alternative: list your business in genuine, relevant directories, such as trade associations, local business directories and established platforms in your industry. These count as local citations and have real value for local search.
Comment and forum signature spam
Dropping keyword links into blog comments and forum signatures. Most of these platforms add nofollow or ugc automatically, and the pattern is easy to spot.
Lower-risk alternative: take part in communities where your customers spend time and add a link only when it answers someone's question.
How to check your current campaigns
List every link-building activity you're paying for and answer three questions for each:
- Would I be comfortable explaining this to a Google reviewer?
- Are the anchors mostly branded, URL or natural phrases?
- Do the linking sites have real audiences in a related topic?
Anything that fails two of those deserves a rethink. You can check how your current anchors look with the anchor text analyzer before deciding.
