Reciprocal Links - permalink - collapse

All > Technology > Search > SEO / Search Marketing

Nepotistic link exchanges where websites try to build false authority by trading links, using three way link trades, or other low quality link schemes. When sites link naturally there is going to be some amount of cross linking within a community, but if most or all of your links are reciprocal in nature it may be a sign of ranking manipulation. Also sites that trade links off topic or on links pages that are stashed away deep within their sites probably do not pass much link authority, and may add more risk than reward. Quality reciprocal link exchanges in and of themselves are not a bad thing, but most reciprocal link offers are of low quality. If too many of your links are of low quality it may make it harder for your site to rank for relevant queries, and some search engines may look at inlink and outlink ratios as well as link quality when determining how natural a site's link profile is. See also: Indexing Timeline - Matt Cutts states that sites which have many low quality inbound links and / or outbound links may struggle to rank or even get deeply indexed by Google.

The referer information can also be accessed as document.referrer within JavaScript or via the HTTP_REFERER environment variable (accessible from scripting languages).

Relevance or Relevance ranking - permalink - collapse

All > Technology > Search > Enterprise Search

Relevancy is the measure of how well the indexed page answers the question. Only the searcher can actually define how relevant a document is, in relation to their query: there is no way to automate it. When there are many query matches, the search engines must rank the results by relevance score, sorting the results listing so that the pages most likely to be useful will appear first. Varying algorithms are used to define relevancy.
