Marikina City, Philippines (PressExposure) November 24, 2009 -- SEO or search engine optimization is one of the many internet marketing techniques used by many web masters to increase their visibility in any search engines, particularly in major search engines such as Google and Yahoo!. There are currently two types of SEO techniques used for a successful SEO campaign. These are the on-page and off-page SEO. Many consider that off-page influences are given more weight than that of on-page SEO factors. However the use of on-page SEO techniques increases the chances of a website getting indexed by different search engines. So what are the techniques used for a website to get indexed?
Website Directories Directories are one of the many ways for a website to get indexed even without the help of off-page SEO factors. A website is usually indexed through search engines' crawlers. Crawlers have only one main objective, to find pages for their algorithmic search results. Pages that are linked from other search engine indexed pages do not need to be submitted because they are found automatically. Some search engines, notably Yahoo!, operate a paid submission service that guarantee crawling for either a set fee or cost per click.
Two major directories, the Yahoo Directory and the Open Directory Project both require manual submission and human editorial review. According to SEO Philippines consultants, Google offers Google Webmaster Tools, for which an XML Sitemap feed can be created and submitted for free to ensure that all pages are found, especially pages that aren't discoverable by automatically following links.
However, search engine crawlers may look at a number of different factors when crawling a site. Not every page is indexed by the search engines. Distance of pages from the root directory of a site may also be a factor in whether or not pages get crawled which is why its very important to include a sitemap so as to make it easier for search engine crawlers to crawl the whole site. Another factor is that if the website is too long, Google would usually truncate the website to just crawl only half of a website.
Cross Linking Other than the techniques used in off-page SEO, such as link building, links within a website is also very popular important in on-page SEO. Cross linking is a method used between pages of the same website. Even though a website isn't optimized for SEO, this method is still used by many web masters. In SEO, links pointing to a certain page makes it important for search engine crawlers, which is why giving more links back to a website's main page as well as inside linking increases the likelihood of websites to rank high in PageRank.
Off-page SEO works simultaneously with cross linking. Link building would usually target the same page in which cross linking are concentrated to further increase the success of SEO campaigns both for on-page and off-page SEO.
Content Optimization Content optimization is divided into several parts, the first is the content visually seen by visitors and those that are only seen by search engine crawlers. Content seen by visitors are the text content as well as images. Text content is very important. Keyword rich text in the webpage and key phrases increases the chances of a website getting indexed by search engines as well as ranking high in many major search engines. Placing keywords on key phrases, such as bolded or highlighted titles and subtitles, weight as much as the rest of the contents are.
Contents that are only crawled by search engines are those found in codes. The use of CSS to make the code shorter is very important for on-page SEO so as to make it easier for search engine crawlers to crawl the whole website and index important keywords of the website. According to SEO Philippines consultants, the use of HTML tags such as the use of
