Spams comes in different flavor. Spammers have already done their best to ruin email, blogs and forums, and now they continue to pollute search engines results (or SERPs). So-called search engine spammers engage in activities to push up the rankings for searches related to their websites in ways that are not approved by the search engines. Search Engine Spamming (or Spamdexing) involve promoting pages and sites with little real value that contain primarily re-directs to other pages, list of links, scraped (copied) content, etc.
There are many techniques for spamming the index of a search engine, and they can be broadly classified in two groups: content(or keyword) spam, and link spam. Content spam refers to changes in the content of pages and include techniques such as keyword or meta tag stuffing and scraping content, while link spam takes advantage of the link-based algorithms and involves spamming techniques such as link farms, page hijacking and buying links.
Warning
When you start your linking campaigns, avoid spamindexing techniques that create unnatural liking to your site. Although these methods, commonly refered to as “black hat SEO”, may have some effectiveness in the short-term, they have little chance of long-term success in the SERPs and may become permanently banned from search results. Moreover, you could be in trouble if someone file a DMCA complaint to your web hosting company and advertising partners that are helping you to monetize content.
The techniques and approaches described above are all ultimately designed to improve search engine rankings growing the number and quality of links that point a website. Combing these techniques can be very valuable for your online business.
