A Zibo website construction company to build a website after the success of its ranking can not be unchanged, leading to changes in website rankings have different reasons。Here are some reasons for changes in website rankings:

        First, weight changes lead to ranking fluctuations, resulting in website construction rankings floating。 The phenomenon of the rise of the ranking of the whole station is often seen in the new station, and the overall ranking will rise after the assessment period, and the keywords that have not been ranked in the past have also appeared。In addition, the accumulation of time leads to the increase of weight is also an important reason. Through long-term data observation, the author finds that the change form of the ranking of the whole station is not a "slow step", but a "leapfrog" phenomenon after reaching a certain weight accumulation。The decline in the ranking of the whole site means that the website is downgraded, and it is necessary to check the reasons in time and take remedial measures, otherwise the situation will deteriorate further。　 　        Second, the algorithm change causes the ranking to fluctuate, resulting in the ranking of the website construction。 Synthesize the recent 628 incident of Baidu and the statement afterwards，The application of Google Penguin algorithm and the performance of recent updates，It can be found that both major search engines have significantly improved the score of optimization in the site，Due to the interference of the artificial external chain, it is difficult to analyze the user experience effect of the website，The weight of the external chain in the algorithm is reduced。In this update, many sites that have not done external chain construction can also get better results, and in the recent test, the author also found that the probability of non-original articles grabbing the ranking is minimal。　 　

        Third, the ranking is "recovered" phenomenon, resulting in the ranking of website construction floating。 　 The phenomenon is often seen in the old station pseudo-original and new station assessment period, the search engine in the page after the first to give its good ranking, and then do further data analysis to judge the quality of the content, generally determine the final results of the ranking takes one to two days。If the comparison database finds that there is a high degree of similar information during this period, or the calculation finds that the page weight does not meet the ranking standard, the ranking will be considered to withdraw。　 　       

        Fourth, the ranking "not released" phenomenon, resulting in the ranking of the website construction floating page included but did not give ranking, is a headache for many webmasters。There are several reasons for this 　　

        1.The keyword setting is not accurate, and it is difficult for search engines to judge the target keywords of the content。For keywords bold or add color, if the inner page can also be freely set, the effect is better。 　　

        2.The content is not related to the topic of the site。Publishing content unrelated to the theme of the website reduces the relevance of the whole site, such as medical websites publishing financial and stock information is obviously contrary to the user experience。　　 

        3.There are unstable factors on the page, and the search engine gives the assessment period。Many changes in a short period of time after the content is published, or a sudden increase in a large number of external links, will be regarded as "unstable pages" by search engines and not give ranking。After the stability of various factors, the ranking can be restored to normal when the internal page snapshot is updated. All in all, if you want the website ranking to be stable and unchanged, you should pay attention to some details and why the ranking changes。
