There are many pages of articles online about how to check if you are being raped. Here, Jack Ma summarizes them and writes them in more detail. If there is anything wrong or missing, friends are welcome to come to my blog to make suggestions. What I have sorted out is basically the following. In fact, there is only so much theory. SEO focuses on experience and practice. Doing it yourself is the most practical way, and the things you learn are real. I have just joined SEO not long ago, and my skills are very good. Friends who are doing SEO are welcome to share their experiences, and the big guys can help me.
Many friends who build websites will have this doubt. When you update persistently every day, suddenly one day you find that the website has been demoted, and you did not cheat. Then there may be the following situations:
1. The server IP address was blocked by the search engine.
Now first find out the IP address of your website. You can basically know it. If you don’t know it, you can check it in the webmaster tools. Then check what websites are under this server IP. You can query and enter your IP address on this website http://www.51zzl.com/dnwl/fuwuqi.asp, and the corresponding websites can be found. (Maybe not all are found) Then record these sites and search for inclusion in the search engine: site: the site just recorded. Check whether these websites are included. If they are not included, they have been K. If they are included and the snapshot date is relatively recent, you can use the friend link check tool in the webmaster tools to check whether the site's friend links are affected by K. Go to this site, thereby inferring that this site has been demoted (because it is the same IP) and is implicated in your site.
There are a few points regarding the issues involving demotion:
1. Friendly links 2. Blog backlinks 3. Site backlinks 4. Soft articles 5. Abstracts; of course this also includes anchor text in soft articles and abstracts.
Of course, before doing this, you need to find out whether the server IP under your site has been blocked. Generally speaking, the server IP address is unlikely to be blocked by search engines. If this is really the case, then you should change the server.
2. URL keywords are abused, update problems and spam external links. (Generally, as long as you make your own website, those who use dim sum will not use the black cat method)
1. First check the density of the keywords to see if they are too dense. Also, be natural when doing these keywords. Being too forceful will only do the opposite.
You can check the keyword density in the webmaster tools http://tool.chinaz.com/Tools/Density.aspx
For example:
Keywords: Legendary private server website URL: www.jxtcms.com.cn
Total page text length: 785 characters
Key string length: 4 characters
Keyword frequency of occurrence: 9 times
Total key character length: 36 characters
Density result calculation: 4.6%
Density recommended value: 2%≦density≦8%
This density is more suitable for search engines.
2. Update issues causing derogation
Indeed, many people don’t know that information updates can also affect demotion. Yes, updates are easy enough to attract spider weight and make search engines pay more attention to you. But spiders come to crawl your site every day, but your updates change too quickly. Today it will be about this and tomorrow it will be about that. The positioning is not good. Do you think spiders will like your site? Therefore, the positioning must be accurate. For example, if you are traveling, update travel information, and don’t mention anything about medical care, games, etc. What's also needed for updating is a regular pattern. Update more than a dozen chapters a day, then not update for 2 or 3 days, and then continue updating. It's better not to do it. Even if you update it once every three or four days or once a week, that's still good. Therefore, positioning updates should be determined according to the size and industry of the site, and then determine your rules. It doesn't matter if you update less, but you can follow the rules. Many new sites suffer from the frequency of updates, ranging from hundreds one day to dozens the next day. After it is included, you can check the keyword rankings yourself. It will definitely have an impact.
Finally, there are a few points to mention. You should not modify the homepage of your site frequently. If you change the title and description at every turn, this will have a huge impact on keyword rankings. In fact, the most important thing about a website is user experience. What your website can bring to users who come to your website, what information they get from your website, and whether it is helpful to them can be said to determine the life or death of your website. Needless to say, Google is a great example.
