If you have worked with any SEOs, you may know that the search engine does not have the same view as us, or our website is seen differently by the spider of search engine. What is search engine spider? You should know at first how search engine works. A search engine must have a database of enormous websites. It’s the job of search engine spider to crawl the Web and index pages, which are stored in a database and later use various algorithms to determine page ranking, relevancy, etc of the collected pages. While the algorithms of calculating ranking and relevancy widely differ among search engines, the way they index sites is more or less uniform. Therefore, it is very important to know what spiders are interested in and what they neglect. First at all, the search engine or spider can not see any words on your image. The spider can only recognize the word in HTML. So do not put any of your keywords on the image. Flash, JavaScript are also NOT visible to search engines. Frames are a real disaster in terms of SEO ranking. All of them might be great in terms of design and usability but for search engines they are absolutely wrong. Secondly, the spider visits one web page from the right to the left, so we recommender you to put your important keywords in the left side and leave the navigation menu to the right if it is very long. Generally, a web developer will put the navigation bar on the header of page, it’s ok, but try to put some important keywords or one paragraph just after the navigation bar, because the spider regards this place as the most important part of the page. Do not try to list many keywords at meta description or meta keywords to improve your rank, because today the search engine spider can not see the meta description or meta keywords. The search engine spider simulator will be so useful for you to find if your web page has been well designed for the search engine. It also helps to see with the eyes of a spider where keywords are located among the text of the page. So, if you choose a web design company, you should also think about how the design factor may affect the view of search engine spider.
