Advertisers can choose to exclude by Topic was such as profanity or suggestive content and can also exclude by Page Type . Advertisers can select between various types of pages including forums, parked domains and error pages. This all helps to give up advertisers to greater sense of confidence that only genuine prospects customers (that are highly qualified) are actually clicking through on advertisers pay per click adverts.   Search engines make money primarily through advertising revenue. Text based advertising is normally presented as sponsor results at the top of organic search listings. When users click through from an advert for the search engine to the advertisers website, the search engine makes money .Sometimes uses are not entirely sure of whether or search result is an advert or a natural listing.     Keyword Use in Domain Name Keyword Use in Page URL Keyword Use in Title Tag Keyword Use in Body Text   Guidelines & SEO -   The Google Toolbar -   The Sandbox - Google supposedly stops new websites form getting high rankings too quickly by applying what has been dubbed the 'sandbox' factor to their ranking algorism (to use an ice hockey analogy of a naughty player being made to wait before getting out on the ice). This ensures webmaster content can be measured over a time period, and inbound links are naturally accrued (and not artificially inflated through mass link exchange or other dubious means). The sandbox is a reflection and measure of trust in a website and webmasters. Therefore, webmasters have to prove long term commitment and cannot expect instant high search engine ranking positions (SERPS).   The Supplemental Index - Google has created a second index of results called the Supplemental Index, which it displays after the main index.  Web pages that appear in the Supplemental Index are of less importance than those appearing in the main Index...   "From a user perspective, this means that you'll be seeing more relevant documents and a much deeper slice of the web, especially for non-English queries. For webmasters, this means that good-quality pages that were less visible in our index are more likely to come up for queries." Google Blog.    Most sites have some of their pages in the Main Index as well as a proportion in the Supplemental Index. Users will rarely view a result from the Supplemental Index above the Main Index.  The main reasons that WebPages appear in the Supplemental Index are as follows:- Duplicate or Little Webpage Content - of your WebPages consistent of only a few dozen words then they are less likely to be of interest to readers and are therefore deemed of less importance by Google. Similarly, if have a particular duplicating content (web pages on a single site contain the exact or significantly similar content), when only one version is actually relevant to the user.  Try and have around 600 words on each page to provide a rich mixture of textual words that will provide something interesting for the user to read; Poor Quality Inbound Links - its common sense that the more exciting, informative and interesting your site is, the more other websites will put a link to it.  Why would a 3rd party site want toi link to a website with a couple of pages or boring unimaginative content?   Site Links - site links often appear in the search results following a website name or brand name.  Important Internal links are displayed to help users quickly access internal pages directly from the search page.  The algorithm appears to only show a website's site links where that website; has a top search engine, is over one years old and has strong inbound links to those particular links.     back to top
