Every website has its own products, and it is the most critical step to select the keywords needed by its products and optimize them. The choice of keywords directly leads to whether users can search for you and determine their main optimized keywords. For the choice of keywords, you need to determine the main keywords first, such as one-night stand, which is the core keyword. After that, love stand's keyword mining and Jinhua's long tail keywords are used to expand the search scope of main keywords, and then the key words are determined by the analysis index. It is suggested to choose three keywords for the title, and do not put the brand name and company name in front, which is very unfavorable for optimization. Key keywords should appear in the description overview as much as possible, which is very useful for improving keyword density and optimizing layout. The content of the description must be a complete paragraph, not like a title. Recent observation shows that many webmasters' descriptions are written by imitating titles, but they don't know the harm of writing like this. The number of keywords should be controlled at about 75, and the contact information of enterprises should be left inside. Many users will not enter the website, but directly look at the title or description of the website and contact you directly if they feel that they are in line with their own tastes. For Baidu's keywords, it has no effect on optimization and does not need to be set. Second, the layout of the station, website construction The layout of the station is a website that must be done. A good and clear website construction can not only improve the user experience, but also help Baidu optimize. Try to lay out the density of keywords on the website, and don't optimize for the sake of optimization. The key word of piling up is taboo. The internal optimization of enterprise websites can be divided into three steps. The first is the optimization of the home page, where 1-3 keywords can appear, which can provide users with an easy-to-understand route. Don't use JS and flash to navigate or important articles or link to other pages, which is not conducive to spider crawling. The second is the optimization of classification pages. Long tail words on classified pages can be locked according to keyword search tools. Generally, 1-2 keywords can be added to a classified project. If the keyword is less difficult than the main keyword, it can be placed on the column home page or the classification home page. Third, the article page optimization. General article pages are full of huge keywords such as low search volume and long tail words. Third, the update of content is the most important. Fourth, seo optimization of strong external chain mainly focuses on optimizing keyword ranking from two aspects: content and external chain. It is very good to leave your own website links in official forums or local government forums for the release of external links, as well as industry forums that can send external links. Search engines believe that the more external links are generally made, the more popular the website is, and the natural weight and ranking will be greatly improved. There are not many external links, but in terms of quality, the external links published by general industry websites are related portals and related forums. Moreover, if the general content essence can be recognized by the masses, it will be reprinted countless times. Why don't you use someone else to help you send the chain?
