How to check whether your own website has been penalized by search engines?

　　In the process of website optimization, we often run into cases where our optimization methods are inappropriate or overdone, causing search engines to demote the site. But how do you tell whether a website has been demoted? Many people doing SEO may not be very clear on this. So how do you check whether your own website has been demoted by search engines?

　　First: Check the search engine's indexing (site:domain)

　　1. After site: returns the pages indexed by the search engine, check whether some of the indexed pathways are reasonable, and rule out whether the cause is a large number of dead links on the site. If you find that the site has many dead links, then you can confirm that the demotion was caused by those dead links, and you need to deal with them.

　　2. Check whether the search engine has indexed many pages with no content, duplicate titles, or duplicate content. If so, you need to enrich or delete the corresponding content.

　　Second: Check the search engine's related domains (domain:domain)

　　1. Check whether there are many junk external links among the related domains; too small a number of junk external links will also cause a demotion.

　　2. Check the search engine's related domains on the first ten pages, look at more pathways containing blogs and forums, and check whether the pages that originally carried your published external links have all been deleted.

　　Third: Statistical analysis of the data

　　1. Statistical analysis of search engine indexing data. Before determining that a demotion has occurred, you must pull out 2-4 weeks of search engine indexing statistics for analysis. If indexing has dropped but the update frequency is fine, then you can rule out a content quality problem — it should be external links or some other issue.

　　2. Operation records. Normally you must get into the habit of keeping statistics on website operations, especially records of major operations such as site redesigns and upgrades and URL changes, because these operations can all cause a site to be demoted. So when a marketing-oriented corporate website is demoted, we can use these operation records to determine which operation caused it.

　　Fourth: Comparison across search engines

　　1. Observe several websites in the same industry and see whether the demotion is widespread. If most sites in the industry have been demoted at the same time, that indicates the search engine's algorithm has changed. At that point, check whether sites in the same industry share a common problem, such as all having content quality that is too low. Find the common demotion factor and optimize for that factor.

　　2. Comparison across different search engines. You can compare rankings across Baidu, Sogou and 360. If several search engines all show a certain decline in indexing, then it is very likely a server problem, causing unstable browsing of the mobile marketing website and slow page opening speed. At that point you must address the stability of your hosting space.

　　3. Whether it is a new website. A new website generally means a site that has been indexed for less than 3 months. Because a new site has not yet passed the trust period and has no credibility, it is very prone to ranking drops. Generally, for the first 3 months a new site need not worry about ranking fluctuations, because this is entirely normal.
