Because the search engine algorithm details are the core secrets of every search engine company and have never been made public. Therefore, when a website appears abnormal on a search engine, most webmasters will suspect that their website has been punished by the search engine.
There are many articles about website penalties in the SEO industry, and there is also a lot of controversy over whether search engines should punish websites that do not follow the rules. You will also find that search engines will not publicly state which behaviors will lead to penalties for lowering the website ranking; they will only explain which behaviors will cause the website to be blocked by search engines. Both can happen, but for different reasons.
There are many reasons why a website is blocked by search engines. Hiding, keyword stuffing, inappropriate linking strategies or even over-optimization can lead to your site being blocked by search engines.
After a website is blocked, you can apply for restoration. All you need to do is correct the problem and wait for the search engine crawlers to crawl the site again. After removing the offending policy, the website can be returned to the search engine's index - but this process may take up to half a year!
But what you may encounter is not that the website is blocked, but that the website ranking suddenly drops significantly. This is most likely not due to search engine penalties, but to a problem with the website or the website's server. Here are some common reasons:
Search engine algorithms change. Search engine designers will continue to optimize the algorithm, so sudden changes in website rankings are also likely to be due to changes in the way crawlers retrieve the website. Therefore, we must pay close attention to changes in search engines and make corresponding improvements to the website.
Server and server hosting issues. If the server is down or running slowly, the crawler will have difficulty retrieving the website, which may even cause the crawler to give up retrieving the website. In some cases, some website hosts block certain search engines, either because of customer complaints or because crawlers have caused some problems with their hosting services. These will lead to a decline in website rankings.
robots.txt is inappropriate. Robots.txt is a very useful tool in the website, but if this file is not written correctly, it will cause the crawler to not completely search the website, or even not search the website at all. Make sure the document is written correctly to avoid a sudden drop in your website rankings.
The link is broken or considered cheating. Your link doesn't have to actually be cheating. But if it is considered cheating by search engines, crawlers will not crawl the site. Broken links can also hinder crawlers from retrieving your website. Any problem that will affect the crawler's ability to retrieve the website will cause the crawler to resent it.
Other website redesigns have improved the relevance of the website to search terms. This is indeed possible. There is no such thing as perfect SEO. Other websites are also constantly optimizing their websites and trying to improve their website rankings, and it is not ruled out that they can achieve better results. All that can be done in this case is to further optimize the website, publish new content, and make the website more attractive to visitors.
So, if your website’s ranking drops for no reason, check carefully to find the problem. If you can fix it, fix it as soon as possible; if you can't fix it yourself, seek help from others immediately. What to do if you get blocked? Fix the problem as soon as possible so you don’t make the same mistake again in the future. This lesson is very costly. The high cost of not showing up in search results for several months will certainly teach you the importance of following search engine rules.
