Google Site Search is a rebranding and enhancement of the existing Google Custom Search Business Edition.
Google Site Search is intended for organizations that want to add Google search functionality to their websites. It has three main improvements over the former custom search offering: it allows for synonym matching, results tweaking, and indexing of so-called â€œdark webâ€ content.
If you a run a site that often refers to terms by their acronyms, or commonly uses different phrases to describe things, you can upload a list of synonyms to Google and it will treat them the same when a user searches within your site.
If youâ€™re a news site that tends to place a premium on newer content, you can bias content based on its date, forcing the newest results to the top. Similarly, if youâ€™re an online retailer or provider of some other type of content, you can give preference to results for that content (in the online retailerâ€™s case, any product pages where visitors might go on to buy things).
Google Site Search mainly relies on the standard Google crawler when scouring your site. But you can also hand it special sitemaps so that it recognizes areas of your website that might typically be overlooked by the crawler. These are results like those hidden behind forms or available only through intricate database queries.
Perhaps most compellingly, Google Site Search can be visually customized to match the look and feel of your website. This isnâ€™t a new feature (it existed in the previous business edition) but something perhaps overlooked by most site owners. When you implement site search, you can customize the appearance with a WYSIWYG editor, or even request a raw XML file that can be parsed and displayed anyway you want (you donâ€™t even have to include Google branding on your results pages).
