未进行关键词分析如果不对关键词进行恰当分析的话，就会造成很多问题，包括：方向不明确、关键词配置不合理、排名效果差、ROI低等，所以一定要先对关键词进行分析。
If keyword analysis is not conducted properly, it can cause many problems, including unclear direction, unreasonable keyword configuration, poor ranking effect, low ROI, etc. Therefore, it is necessary to analyze keywords first.
2、缺少导入链接很多网站的优化都存在收录问题，检查一下不难发现，很多都是因为缺少导入链接。互联网中，网页与网页的关系是通过链接来建立的，如果网站和外界没有链接，没有任何联系的话，就成了一个孤岛型网站，搜索引擎无法知道网站的存在。
2. Many website optimizations have indexing issues due to the lack of import links. Upon inspection, it is not difficult to find that many are due to the lack of import links. In the Internet, the relationship between web pages is established through links. If a website has no links or connections with the outside world, it becomes an isolated website, and search engines cannot know the existence of the website.
3、采集大量的文章搜索引擎不会给予互联网中高度重复的文章好的排名的，网站上如果包含大量的采集文章的话，对网站是会有一定的负面影响的。网站建好后，如果没有或者只 有很少的原创的实质内容的话，会给用户带来了不良的浏览体验，也会给搜索引擎留下了不好的印象，为搜索引擎优化带来困难。
3. Collecting a large number of articles in search engines will not give high ranking to highly repetitive articles on the Internet. If a website contains a large number of collected articles, it will have a certain negative impact on the website. After the website is built, if there is no or very little original substantive content, it will bring users a bad browsing experience and leave a bad impression on search engines, making search engine optimization difficult.
4、一味追求网站美观有些网站一味追求美感：大气、好看、美观，其实对网站来说，这些都不是必需的。用户喜欢简洁明了的页面，这样才能带来良好的视觉体验。不要使用大量的 图片和太多的flash，这会造成页面体积过大、页面加载速度慢，大大降低使网站的实用性，也不要再导航上使用图片作链接，这会导致搜索引擎识别网站结构 时有困。
4. Some websites blindly pursue beauty: grandeur, beauty, and aesthetics, but in fact, these are not necessary for websites. Users prefer concise and clear pages in order to bring a good visual experience. Do not use a large number of images and too much flash, as this can cause the page size to be too large and the page loading speed to be slow, greatly reducing the practicality of the website. Also, do not use images as links in navigation, as this can cause search engines to have difficulty recognizing the website structure.
