As we all know, after the site well, we need the opposite of trying to cater to the preferences of the search engine spiders, in order to allow spiders to more than a few times, to increase crawl frequency, increase the number of pages to crawl our site, so we spiders need to open and unobstructed road, we need to make it successful in its freedom crawling crawling page. In short: open flow path, avoid spider traps.
What are the common search engine spiders trap?
1, the site head with large Flash effects, will delay the opening speed of the site, is not conducive to the searcher's user experience, but also not conducive to make spider crawl.
2, a variety of jumps (no principle, no purpose Jump), 301 (Redirect Jump, generally used in the old site to the new site when the change), 302 (direct jump), 404 (error page).
3, the frame structure (such as: iframe tag SEO try to use less frame), the frame structure is not crawling spider.
4, need to log in to registered members can access it, which makes the spider because there is no corresponding "permission" not to be able to successfully crawling content.
Opening has been introduced within the site optimization includes: URL optimization, content optimization and optimization label three parts, then how do URL optimization, should first get to know URL, URL (Uniform Resource Locator) usually named three forms,
Chinese naming
In Chinese form part of the keyword for URL naming than English or Pinyin easier because Chinese do not need to test the product in the form of keywords should consider issues such as separators, and only need to select the directory or page content related keywords. But not all search engines retrieve URL Chinese characters, it is often not recommended for SEO workers.
English naming
In English in the form of keywords for each part of the URL is named after one of the most popular URL naming Currently, Note: Use the actual existence of a word or phrase as the URL of each component of the name;-word phrase must delimiter divided, generally used in the URL "-."
Pinyin naming
Currently, the vast majority of search engines support phonetic form of a keyword search, that is, the search engine can recognize Chinese pinyin form of keywords, so you can also use the keyword phonetic form of URL naming the various components, this is very important for improving the relevance of Chinese pages. Pinyin as the domain name, when the searcher using phonetic search rankings will be in front, because of the high degree of matching.
RUL length, URL length = Internet domain resource type + length + port number + path + file name length length. Search engines crawl the page, the URL of the page length is a certain limit. For exceeding this limit will give up the search engine pages indexed. Moreover, URL of the page shorter, get the current weight is higher. In a full URL, whether it is for ordinary users or search engines, the main keyword appears only once are relatively good. In the URL, you can use the URL delimiters for each part of the name are combined to produce a new phrase (or phrases) to expand the meaning of the URL. Note that the domain name will also be required in the application domain of the problem Frequency of keywords should be avoided in the domain name repeated the same keyword, domain name length does not take too long to fit, regardless of the memory or input is not easy.
Understanding understand URL, so when doing SEO, for URL we should make our corporate website dynamic URL to static, static conducive to search engine spiders, in addition to the necessary shift to make use of 301 treatment, while establishing a 404 can help to avoid open navigation page navigation error; URL length is not easy too long, the URL should not exceed 3-5 keywords, Google Matt Cutts said that if more than five keywords, the right weight will be the url accordingly reduced. Of course, this is relative, not more than five keywords in URL will not get a good ranking, after all, URL is just one part of it, and for a good SEO might be the lack of progress will fight, will not easily give up any one possible place ahead of the competition. And recent studies have shown that better position in the ranking inside, short URL click-through rate is twice as long to get, so order your ranking and click-through rate, better to use a short URL; URL directory name combined file name must try to meet the needs of adjacent between files and directories, directory name and file name is independent of the presence of keywords and keyword combinations arising after an independent existence, combined with the page keyword the content is relevant.
URL optimization, from the early establishment of the station is a factor we must consider is the primary starting point of our late-optimized website, with a good website URL constructed, so that the overall site URL layering, our search will not only bring the user to use very good user experience, but also make our website in the search engines, bring good ranking, will be more helpful for our SEOER when we do optimization.
