1, bad selection and placement of the keywords-you should not choose unique keywords, because there are few search relevance to meet these unique keywords and search for the poor people. Instead, you should always consider using these keyword phrases to be more commonly used by netizens.
2, omit or disregard the title tag-many people directly skip providing title tags, ignoring this highly important and effective search engine optimization weapon. Instead, you should think of a title tag that contains a better search engine for keyword optimization.
3, do not make the content of the site flash-if your site has a lot of attractive images and flash content, these content is best to use text, because the search engine can not read any content other than text.
4. Do not provide sitemap along with your JavaScript menu-If your site has a lot of J Avascript for navigation, then you need to provide a Web site to enable both indexing and retrieval of the search engine, because the search engine can not read the J avascript menu.
5, your site to provide continuous updating of the optimization measures, so that the search engine will be disappointed with your site and alienated it.
6, too much use of META tags-search engine will be too many meta tags to create resentment. In addition, the META tag is slowly becoming the past, tag tag is emerging, the appropriate use of tag is also a good choice.
7. Use images instead of text menus and headings-although it may seem interesting, remember that search engines cannot read anything except text, so if you use images instead of text menus and headings, your site will not be crawled or indexed.
8. Ignore sites that use the same keywords as your site-please focus on the same keywords site by analyzing your competitors to gain additional advantage.
9. Think of the more reverse links the better. Always choose a link to high-quality Web sites, do not have to do with the punishment of the site to do the link, this may also be down the right, if possible, one-way link effect better.
10. The keyword is irrelevant to the content or cannot be found in the content.
While avoiding all of these common search engine optimization errors, if your page rankings still haven't improved, then there must still be several other unresolved issues that you need to consider to improve your site's optimization.
