“Keyword stuffing” refers to be an unethical search engine optimization (SEO) technique. It is the practice of loading a web page with keywords n the meta tags or in content to manipulate a website’s ranking in Google’s search results. The repetition of words in meta tags may explain why many search engines no longer use these tags.
In the past, Keyword stuffing had been used to get maximum search engine ranking and visibility for particular Keyword phrases. This technique is completely outdated and adds no value to rankings now. In particular, Google no longer gives good rankings to pages employing this method. It can be an unwise choice as many search engines penalize for keyword stuffing and they use complex algorithms to detect signs of keyword stuffing, even when it is done cleverly.
Before search engines wised up to this practice, they would return stuffed websites when users searched for the common keywords. Users would suppose that the website was relevant, since it was in the first page of search results and they would click on the link.
With interspersed ads, at best, the site might be a bunch of nonsense; at worst, it might load harmful software on the user’s computer. This practice could be frustrating for people trying to browse the web for information and as a result, search engines refined their algorithms to use a number of markers when determining how much relevant a site is.
Many search engines will flag websites with an unusually high number of keywords, terming them spam, rather than legitimate websites, leading to the alternate slang term “spamdexing” to consider to keyword stuffing.
If a search engine found fourty instances of the term on a single page then it might assume that the page had been stuffed.
