How to avoid the situation where ranked SEO keywords suddenly become unstable?

　　In the process of SEO optimization, many SEOers have found that the keywords they worked so hard to optimize suddenly fluctuate high and low in the latest search engine rankings. So why do keyword rankings become unstable? And how can webmasters and SEOers avoid unstable website rankings?

　　1. Unstable servers

　　Server instability causes search engines to give a website a lower score. Never underestimate the impact of server stability on keyword rankings. If the server space your website uses is not large enough, or if it is an overseas server without filing (ICP registration), the site is very likely to become unstable during operation. To keep your website server stable, try to use a domestic registered server, or reduce voice program requests, which makes it easier for users to access your website smoothly.

　　2. Frequent changes to the website title

　　As for changing a website's title, seasoned industry insiders agree that the title should not be changed unless there are special circumstances. Frequently changing a website title easily leads search engines to mistake it for a new website and give it a lower ranking; in serious cases, it can even cause the site to be demoted.

　　3. Problems with website updates

　　When it comes to website updates, there is often a period during the update when spiders are blocked, and at that time the new site will show a 404 page prompt; after modifications, a large number of dead links are also likely to appear. Therefore, when updating a website, you must run comprehensive tests both before and after making changes to avoid dead links and 404 pages.

　　4. Weak user experience

　　When a user enters a page and finds that it does not contain the information they need, they will promptly leave the page, resulting in an extremely high bounce rate. When a search engine finds that a website has a high bounce rate, it will judge it to be a spam page and give it a lower ranking. So when you find your website's keyword rankings unstable, check whether the page content meets users' needs, and optimize your keywords while updating the page content.

　　In addition, unstable keyword rankings can also occur when a website is under investigation, when Baidu search algorithm updates or adjustments happen, when keyword density changes, or when a website is penalized by search engines. However, there is no need to worry when keyword rankings are unstable — patiently identify the shortcomings and troubleshoot the problems one by one, and keyword rankings will eventually reach a stable state.
