According to Google, the canonical link element is not considered to be a directive, but rather a hint that the ranking algorithm will "honor strongly". [1] [9] While the canonical link element has its benefits, Matt Cutts, then the head of Google's webspam team, has said that the search engine prefers the use of 301 redirects.
There are a variety of ways in which Wikipedia attempts to control search engine indexing, commonly termed "noindexing" on Wikipedia. The default behavior is that articles older than 90 days are indexed. All of the methods rely on using the noindex HTML meta tag, which tells search engines not to index certain pages. Respecting the tag ...
If a server is configured to support server-side scripting, the list will usually include entries allowing dynamic content to be used as the index page (e.g. index.cgi, index.pl, index.php, index.shtml, index.jsp, default.asp) even though it may be more appropriate to still specify the HTML output (index.html.php or index.html.aspx), as this ...
Bing, Google, Yahoo and Ask now jointly support the Sitemaps protocol. Since the major search engines use the same protocol, [ 3 ] having a Sitemap lets them have the updated page information. Sitemaps do not guarantee all links will be crawled, and being crawled does not guarantee indexing. [ 4 ]
Indexing low priority to high margin to labels like strong and link to optimize the order of priority if those labels are at the beginning of the text could not prove to be relevant. Some indexers like Google and Bing ensure that the search engine does not take the large texts as relevant source due to strong type system compatibility. [23]
Link Equity Transfer: Search engines typically transfer a majority of the link equity (or “link juice”) from the source URL to the target URL for 301 redirects. [ 6 ] Indexing Delays : There might be a lag before search engines recognize the redirect and update their indexes accordingly.
In October 2008, the internal search function was significantly improved, enabling all the functionality already available through search engines such as Google, and also incorporating a number of features unique to Wikipedia, such as automatic identification of redirects and page sections, and more appropriate search rankings. This made the ...
Suppose instead that page B had a link to pages C and A, page C had a link to page A, and page D had links to all three pages. Thus, upon the first iteration, page B would transfer half of its existing value (0.125) to page A and the other half (0.125) to page C. Page C would transfer all of its existing value (0.25) to the only page it links ...
