Search engine robots are called “spiders” or “crawlers”. They travel all over the world through different countries, which are the websites, while the web pages are the regions and the traveling route of the robots are visualized as links between different pages. The Robots inspect individual websites, evaluates and assesses their credibility and after the assessment, passes the information to search engines. The search engines update the index with the database supplied by the robots about individual websites. Once the robots have completed submitting the reports to search engines they make another trip to check the old sites and explore the new websites. This on-going process keeps the search engines updated which leads to periodical modification of the index.
The search engine index is a huge database which keeps record of all documents that robots find on the web and reports to them. This includes all the web pages of different countries and their websites as well as the web content and other related information. In true perspective of SEO, it is crucial for a web page that whatever relevant information it has should be recorded in the search engine’s index. If it is not recorded, then the page would not be found through search and would not project the desired result. This implies that site owners should try all possible methods to implement a strategy wherein the robots visit all the important pages of the website and identify the minutest details listed in the content. To assess the factors that are important for robots during the indexing are :
01) Reliable hosting which is fast – Since search engine robots move quickly, it is advisable to develop and fast and reliable hosting. This would ensure that the server is functioning all the time. This makes it easy for search engine “spiders” to “crawl” the site. A fast and reliable hosting is appreciated not only by robots but also by the web users. However, in certain rare cases the server may be down. But if the hosting problem is persistent and the website does not respond, the robots have a tendency to stop visiting the site. In the long run the website may even be removed from search engine database while the website owner would lose out on sales since the users can not access the site. Therefore, it is suggested to host the site on reliable servers that function quickly and are seldom down. Speed is appreciated both by search engine robots and web users. The quicker the hosting the site loads at equal speed entailing more visitors to the site and more sales conversion. It should not take more than 8 seconds for a web page to load and the similar rule applies to web users who would not wait more than 8 seconds to access the site.
02) Develop a sitemap – This fact is equally important for creating a search engine friendly site. A sitemap can be defined as a list of pages on the website. Normally, there are two types of sitemaps : (a) HTML sitemap which are constructed both for search engines and human users and (b) XML sitemap that is basically designed for search engines only. In order to ensure that robots visit the pages developing an over-all accurate sitemap is mandatory.
