1 the website keyword ranking and website content as a result of website content updates is highly correlated, including, of course, key word density and keyword location, so that if website content is updated, changes in keyword density and location, as well as changes in keyword ranking. High-quality original content can contribute to an increase in the weight of the website, leading to a good ranking, and if the content of the site is of low quality and the user experience is not good, it can affect the keyword ranking, leading to a decline in the keyword ranking, which tells us that it is better not to update or not to update the low-quality website content. The decline in the ranking of key words due to external chains is well known, as is the dynamic process of removing some of them every week or even every day. For example, expired outer chains, some of which were removed and become dead links. For example, over-repeated outer-chain content can be removed from search engines. A reduction in the number or quality of the outer chain affects the ranking of keywords. 3. As everyone knows, due to intense competition, website optimization is a dynamic process, without backsliding, for competitively competitive keywords. If you do not improve, others will naturally fall in the ranking of your website, which is where the keywords are squeezed down, so that we can opt for website optimization, maintain the ranking of key words, analyse competitors in a timely manner, and constantly increase the weight of our website by increasing its distance from competitors, and, of course, for industries that are often less intense, it is better to have no competition crowding you. 4 the optimization of the website as a result of server factors requires a stable server, of course, as quickly as possible, which will facilitate both user experience and search engine capture. If the server is unstable, the timing of the search engine to capture the page will result in a decrease in the weight of the website and a decrease in the number of keywords. 5. Optimizing over-site sites is expensive in a modest way, such as updating the web content in a regular manner, not being able to update one today, as is the case for tomorrow's update of 10 pages, as is the case for external chains. And for example, if too many anchor text points to a page, it can easily cause over-optimization, causing downfalls, things have two sides, and good is bad. The sharp decline in the ranking of most keywords is due to over-optimization. 6-friendly links cause us to develop a habit of constantly checking for friendship links, such as those that have been withdrawn, and you need to remove each other's friendship links in time and exchange new ones in time. Of course, there are problems with each other's websites, such as the downgrading of the websites, and the timely withdrawal of the other's friendship links. 7. With regard to the issue of malicious attacks by competitors, which should also be highlighted, such as the maligning of traffic, by informing the search engine that the site is cheating, thereby resulting in penalties, we need to analyse the website logs in a timely manner and find and understand the pattern of the presence of the search engine on the site. Changes in the ranking of keywords may occur as a result of the reversion of websites and the replacement of servers. In particular, changes to the web title or website description have a significant impact on keyword ranking. The replacement of servers may, of course, also result in a change in keyword ranking, and the search engine can judge the ip address. The problem search engines themselves are constantly being adjusted, and problems are inevitable. Adjustments to the search engine algorithms can be made by all search engines every day, with the possibility of adjusting algorithms, sometimes minor adjustments and sometimes more inherently. The problem of reducing the ranking of short-term keywords over time, which usually recovers within two days, leads to a decrease in the ranking of websites, starting with a calm analysis of the reasons. 10. The slow opening of websites and the large loss of weights due to the hanging of websites, particularly the large number of black chains, is the most important thing to develop a daily practice of backup, in which case the site can be restored directly and cleaned up very quickly. All right, that's all we've done for the decline in the number of keywords on the website, and i hope it will help you all in this situation. Thank you
