Selling links that pass PageRank
I've talked quite a lot before about buying or selling links that pass PageRank. Today I wanted to walk through a concrete example of paid posts and show why the major search engines don't want to be affected by links within paid posts.
Context & Ripple Effects
This post is Matt Cutts closing the loop on an enforcement arc that has been building all year. Back in December 2005 he had already flagged text-link buying as a practice Google wanted to discourage; in October 2007 Google made it official policy that selling paid links can hurt a site's PageRank or rankings, and weeks later Cutts confirmed a PageRank update tied to paid links.
What changes here is specificity rather than severity: instead of restating policy, the post works through a concrete paid-post example and explains why major search engines do not want to be affected by links inside paid content. For a publishing economy where paid posts were becoming a standard monetization route, that turns an abstract warning into an actionable test publishers can run against their own revenue deals.
First-order effects
- Sites earning money from paid posts now face the penalty mechanism Cutts confirmed in October — visible PageRank loss and possible ranking impact — applied to a deal type many publishers treated as ordinary advertising.
- Buyers of paid-post links get a clearer signal of risk: links purchased through sponsored posts are explicitly excluded from what Google wants to count, making such spend unreliable for ranking purposes.
Second-order effects
- Text-link brokers and marketplace operators whose inventory consists of PageRank-passing placements must either adopt nofollow-style compliance or see their supply devalued, since both sellers and buyers have less reason to trade.
- Advertisers reallocate budget away from raw PageRank purchases toward channels that survive Google's stated rules, shifting pricing power toward placements that carry genuine editorial endorsement.
Third-order effects
- If enforcement continues along the path from the 2005 warning through the October 2007 policy to this worked example, the structural outcome is a two-tier link market: disclosed or discounted paid links that search engines ignore, and editorially earned links as the primary ranking currency.
- Publishers who built traffic strategy on selling PageRank face a durable business-model constraint, pushing blog monetization toward ad products that do not depend on transferring search authority.
The trend: Google is escalating its campaign against paid links from policy statements to concrete enforcement, progressively squeezing the market for PageRank-passing placements out of the SEO economy.
