The bait-and-switch tactic with backlinks is one of the riskiest and most condemned Black Hat SEO practices. It involves creating a page with exceptional content, such as unique research or a free tool, with the sole purpose of getting other sites to link to it. Once these valuable backlinks have been acquired, the page's content is changed to something promotional, low-quality, or that redirects elsewhere. This is considered deceptive to both users and webmasters who linked to the site in good faith.
While it might have worked for a while in the past, today's algorithms are much smarter. Google doesn't just crawl once; it periodically re-evaluates pages. If it detects a drastic change in content while the URL maintains the same inbound links, it's a huge red flag. Most likely, that page, and sometimes the entire site, will be heavily penalized, losing all organic ranking. Recovering from this is very difficult because you've destroyed the trust built with the very link base you acquired.
The right and sustainable approach is the exact opposite: create valuable content that lasts. A good resource attracts links naturally and continuously over time, becoming a permanent asset for your site. Replacing it with something poor is killing the goose that lays the golden eggs for a minuscule immediate gain. In SEO, honesty and consistent quality remain the only winning long-term strategy.
