image map - permalink - collapse

All > Technology > Search > SEO / Search Marketing

A set of hyperlinks attached to areas of an image. This may be defined within a web page, or as an external file.

If the image map is defined as an external file, search engines may have problems indexing your other pages, unless you duplicate the links as conventional text hyperlinks.

If the image map is included within the web page, the search engines should have no problem following the links, although it's good practice to provide text links too, to aid the visually impaired and those accessing the web with graphics switched off or using text only browsers.

Inbound Link - permalink - collapse

All > Technology > Search > SEO / Search Marketing

Link pointing to one website from another website. Most search engines allow you to see a sample of links pointing to a document by searching using the link: function. For example, using link:www.seobook.com would show pages linking to the homepage of this site (both internal links and inbound links). Due to canonical URL issues www.site.com and site.com may show different linkage data. Google typically shows a much smaller sample of linkage data than competing engines do, but Google still knows of and counts many of the links that do not show up when you use their link: function.

Incremental indexing - permalink - collapse

All > Technology > Search > Enterprise Search

Incremental indexing enables an efficient combination of freshness and scalability in a search node. The index can be partitioned into different segments (partitions) with different refresh rates. Data is initially indexed in the smallest index where it resides for a given period of time before it propagates a larger index. This procedure repeats itself; once data has entered index P, it stays there for a configurable amount of time before it moves to index P+1. This concept takes place within one search node, and is independent of the partitioning performed using multiple columns of search nodes.

Collection of data used as bank to search through to find a match to a user fed query. The larger search engines have billions of documents in their catalogs.

Index-based security - permalink - collapse

All > Technology > Search > Enterprise Search

The resolution of a repository's document ACL permissions at query time by the index itself through the use of stored meta-data. Using this method, results lists will only include hits for which the searcher has viewing permissions. Compared to post-processing, the index-based security method gives higher query performance and enables the search engine to return correct counts for navigators and related concepts.

Inktomi - permalink - collapse

All > Technology > Search > SEO / Search Marketing

First introduced in September 1995, Inktomi Corporation from California was a key player in the search engine market where it pioneered online search technologies. It initially provided software to ISPs (Internet Service Providers) but then went onto power other well-known web search tools such as HotBot, Looksmart, MSN, regional search engines and others. It ultimately displaced Alta Vista when Inktomi started using a distributed network technology (instead of operating everything on one machine) that enabled them to index more than 1.3 million documents on the web at that time. Inktomi was the first to launch a paid inclusion service that meant websites would receive regular and frequent re-indexing for a fee. It also invented a proxy cache for ISP web traffic called "Traffic Server". During its short life, Inktomi acquired many businesses including Webspective, Infoseek, eScene Networks and FastForward Networks. Once the Internet bubble had burst in 2000, many of its acquisitions were sold off due to the financial collapse of most of its customer base. Yahoo! purchased Inktomi in 2003 which remains central to its search engine database today.
