Similar Entries - Drupal Module

As the name of this module suggests, it finds and presents entries (documents or nodes) that are similar to the current document. The similarities can be in any field of the node (Title and Body fields). Unlike a previous module that required modifying one of the mode tables to add a column that would be populated with keywords and association data, this module does not modify the existing table structure destructively, and so the module can be un-installed without having to meticulously and manually edit the core database tables.

By suggesting similar documents to the reader alongside with a given page in question, the website owner has the opportunity to help the reader gain more in-depth information about the topic of the current document.

Links within a site make it easier to expose otherwise hidden and relatively obscure documents that do not already have links from external sites or search engines. This makes it easier to showcase documents covering topics that the user would have otherwise not sought in search engines. In addition to this human-centric reason to use this module, it is indispensable to have links from one page to other pages within the same website for Search Engine Optimisation. If the search engine is crawling a page, by having links to related documents, it achieves the dual objective of giving the search engine crawler a path to crawl more pages (exposure), and also increases the site-wide SEO by grouping and interlinking documents that cover similar topics.
