1. Repeatedly stacking keywords
Keyword stuffing is something search engines dislike. Don’t pile up keywords in TITLE, Keywords, and Description. Search engines still attach great importance to TITEL. Just write 2 to 3 keywords in TITLE. The other symbolic ones just need to be written, and they have almost no weight. Especially for new sites, you should try to avoid overly obvious optimizations.
2. Randomly change the title after inclusion
Changing the title is a taboo for search engines, especially if the search engine has already included the website. When you change the title at this time, you need news. The lighter ones will gain power, the more severe ones will be K. Because the title of my breast network was recently changed, the snapshot was reverted for a week and it has not recovered yet.
3. Complete collection of website content
This is very annoying to search engines, especially Baidu. The collected websites will also be included in Baidu, but they will be deleted from the database slowly. Serious websites will be K later. So don’t collect them on a large scale. Even if you collect them, you should change the titles, start very late, and make them pseudo-original. .
4. The code is too long
Spider reads web page content from web page code. If the code is too long, it is not conducive to spider crawling, and long code will load slowly, which search engines do not like. It is recommended that you use DIV+CSS to build the website, which is relatively small in size.
6. Website content and theme are not attached
If the content of the website deviates from the theme, search engines will naturally not like it, and the weight will not be high.
7. The website is all flash or pictures
FLASH animation websites are beautiful, but not practical. Search engines do not crawl FLASH or pictures, which is not friendly to search engines. And don’t have too many JS calls and Frames on your website, as these are not liked by search engines.
8. Too many junk external links
Some newcomers think that the more links, the better, and use bulk sending software to send spam links everywhere. Spam links have long been useless, and they continue to be useless and harmful. If you do too much, you are not far from K. Link quality over quantity.
