What are the reasons for the instability of the website keyword rankings?

Someone asked today, my website keyword ranking why not stable ah? In the world of SEO, the site's keyword instability can also be divided into station factors and factors outside the station. Below I said that the site keyword ranking instability of the specific reasons.

Factor in Station:

1. When this happens on your website, the first one you need to check is your server. If it is often not open, or open speed is very slow, this is very affecting the spider crawling. Your site keyword ranking instability is understandable. I have always said that the space or the server is your optimization of the fundamental, no matter how cool your optimization, as long as you server problems, then your work is basically equal to white do. So what kind of server is conducive to optimization, stable, open fast server is a very good server.

2. Website revision. If your server does not have any problems, then you should think about your site has recently been revised. If your site is revised, it may also lead to a decline in your ranking. Here should be asked, why other people's website to make some changes in the time will not you things? If your site is updated with snapshots of your site after your revision, this is basically no problem. Just say here, understand people naturally understand.

3. The station updates very few, only relies on the outside chain to do the ranking website. The key rankings of such websites are very unstable.

4. The chain of external chains has been greatly reduced.

5. The content of the website is too rubbish. Since the Baidu algorithm update, I found that many stations because of the content of the relationship between the ranking is not stable. Some may even be directly by K.

6. The website is not updated for a long time. If your site is not updated for a long time, then the spider will think your station is a "dead stop". It is also reasonable that your rank is unstable.

7. Excessive optimization. Optimization also has a step-by-step process. If your site is too optimized, it can cause search engines to suspect you are cheating. At this point, your ranking will be very unstable.

8. The website has the cheating behavior. This will not explain.

9. The website is Hung horse. Ditto.

Outside the station factor:

1. Your website keyword competition is intense, then the rank has the fluctuation is normal.

2. Friendship links out of the question. In fact, when I analyze the site, only in the second place. Baidu is very famous "sit" punishment, if your friendship link site is down right, then your site will be "sit".

3. Baidu algorithm adjustment. Baidu algorithm every time the adjustment will die a group of sites, down the right to a number of sites.

4. The user experience is low. Actually this is in my feeling if you are not on the front page, you can ignore this factor.

5. Aunt Baidu. Do Baidu people are aware of things.

The above is the site I met the instability of the factors, we can compare to see their own site is because of what the ranking is not stable. Of course, there must be a situation I did not meet, you are welcome to comment! Appreciate!
