优化对于做网站的人来说，是再熟悉不过了。但是，在做优化的过程中，很多人犯了许多错误。我们在做优化的时候，要尽量避免这些错误。 1.避免经常改动网站TDK 众多周知网站TDK三个标签是网页或者网站在排名中起着非常重要作用，尤其是现在title、description标签是不能经常变动的，现在搜索引擎重点关注这两个标签，keywords标签在参加排名时的权重已经很小了。一般经常做seo的同学不会范这样的问题，只有行业新手可能会出现这个问题，如果你改一次搜索引擎就会重新抓取一次，如果是刚建立的新站，那么搜索引擎会延缓收录你的站，或者你的网站和网页已经被百度收录了，但是不会放到搜索前台，也就是只存在于搜索引擎的索引库中而用户是看不到的。 2.避免低质量链接 seo行业有一句话就是内容为王、外链为皇，可见外链的重要性，优质外链更是被搜索引擎青睐。网站在搜索引擎中的排名、权重、关键词排名都不能缺少优质外链的帮助，如果不注重外链质量而只注重数量就会造成大量的垃圾外链，时间长了或者达到搜索引擎的一个默认量网站就会产生波动，因此要尽量避免低质量链接。 3.避免网站友情链接出现问题 虽然网站被降权的原因很多，但是网站友情链接绝对是其中非常重要的一项，如果网站被降权了，要及时检查友链，看对方网站是否被k、无法访问、访问缓慢等问题，如果有较多的友链网站对方没有链接到自己网站，那也是需要及时处理的，要不然也会出现网站数据不正常的问题，所以在网站友情链接这一块一定要及时查看。 4.避免选择难优化的关键词 什么是难优化的关键词呢？可以通过什么方式判断这个词是否容易优化呢？难优化的关键词就是竞争度和热度比较大的关键词。那么可以通过什么方式判断这个词是否难优化呢？可以通过百度指数、搜索引擎自然排名、百度推广、关键词网页数量等数据来判断这个词是否容易优化。 The optimization is more familiar to the people who do the website. However, in the process of optimizing, many people made a lot of mistakes.

General SEO students often do not fan such problems, only the industry novice may appear this problem, if you change a new search engine will grab one, if it is just a new station, then the search engine will delay included your station, or your website and web page has been Baidu included, but do not put the search index library is the front, only exists in the search engine and the user can not see. 2., to avoid low quality link SEO industry, there is a saying that content is king and outer chain is emperor, so we can see the importance of external chain, and high-quality chain is also favored by search engines. The site in the search engine rankings, weight and keywords ranking are not the quality of the chain to help, if you do not pay attention to the quality of the chain and focus only on the number of it will cause a lot of garbage outside the chain, a long time or reaches a default amount of search engine website will produce a wave, so try to avoid low quality links. 3. avoid the site Links problems although many websites were down the right, but the site Links is definitely a very important one, if the site is down right, should promptly check the chain, see each other site is k, can not access, slow access and other issues, if there are many friends of the chain website no other links to your site, it is also the need for timely treatment, otherwise there will be problems of abnormal website data, so check on the website Links this is a must. 4. what are the key words that are difficult to optimize by avoiding the choice of the key key words that are difficult to optimize?
