But we need to pay attention to doing as much relevance as possible in the subject content of the text. The relevance of web keywords is equivalent to the keyword density I usually understand. And natural presentation, which can give search engines a better evaluation of the relevance of web pages. Because there are many noise modules in the webpage, the search engine spider may remove these modules when crawling and then evaluate the relevance. If your webpage relevance is in the noise module, it may not be relevant SEO When diagnosing, it is also a very important aspect to diagnose the relevance of web pages and control the signal-to-noise ratio of web pages. It can improve the relevance of web pages and ensure the stable promotion of keyword ranking.
After a long time of optimization, we must have encountered such a situation: a short-lived phenomenon of keyword ranking. First, make sure that the single keyword ranking comes from the website weight. This phenomenon is mostly a newly updated webpage, which will rank very well on Baidu, and some even rank first. For example, Baidu recently launched a new website, with little competition for keywords Website production As long as it is included, it may be listed on the home page, but this phenomenon will rapidly decline after a short day or a few days. Sometimes even the first ten pages can not find many friends have encountered this problem, and this phenomenon has also been studied as a case certification. Next, I will talk about the SEO diagnosis idea of this phenomenon.
Or the weight of a single page. As long as the weight of the page is enough, the keywords on the current page are likely to get a good ranking. However, with different keyword layouts and locations within the page, the weight distribution of the keywords is also different. Therefore, the following three factors affect the vacillation of keyword ranking:
1. The weight of a single page;
2. The position importance of keywords in a single web page;
3. The relevance of keywords in a single web page.
Then, according to the actual situation of the website, a series of SEO diagnosis work was carried out to carefully analyze the factors that can affect the keyword ranking among each factor. The factors that affect the ranking of web keywords start from these three points.
1 Web page weight
It is necessary to understand some basic algorithms for search engines to evaluate the importance of a web page, and to determine the weight of a web page. One of the algorithms that I talk about most but few people pay close attention to is PageRank algorithm. Search engines judge the importance of web pages through the votes of many web pages on a single web page in the Internet. The factors that affect the voting quality include the weight of the voting page, the relevance of the voting page, the form and diversity of the voting, the number of votes and so on. Therefore, it is necessary to make an analysis of these aspects when diagnosing this web page.
That is, the friendship links on the home page of high weight websites, and the weight of voting pages are easy to understand. This is the best way to try to buy if you can't exchange, but buying links is cheating. Search engines are strict about similar phenomena, which has certain risks. The other is the content page of a high weight website, which depends on publishing, such as SEO soft articles to A5 and chinaz and other high weight platforms, Attracting website reprints is also a good way.
For example, if you come to your own B2B platform, the relevance of the voting page is also important. If you come to the polls, they are all relevant pages. Your own third-party blog, your own internal link support, and even some excellent website recommendations in the industry, then the search engine will think that your website relevance is better, which will definitely help you to improve your keyword ranking. When diagnosing website weight, we will focus on relevance.
In order to let everyone know that various forms of links have different effects, the number of votes goes without saying that the number and diversity as well as the form of voting are put together here. The website chain from more root domains will bring greater assistance to the weight of the website, so this is also an important part of SEO diagnosis.
2. Keyword position in web page
Important keywords appear in important positions, and do the right thing when it is right. This is a very important principle of SEO, and the position of keywords in the web page can be more prominent, then the ranking of the website will certainly be better. Obviously, the keywords placed in the titl tag and h1 tag must be highly rated by the search engine, and the keywords here generally do not change, so the shake of keywords is relatively small, and the ranking will be relatively good. Of course, the links and keywords at the top are also relatively weighted. For example, the ranking of website keywords that are ephemeral is mostly presented in the updated article page keywords of the website, because the overall link structure of the website has changed with the change of the article link. When the key words appear on the home page of the website, If the top position gets the website weight given by the home page, the page will get a good ranking. If the number of updated articles increases and the keyword links fall behind, the weight will naturally decrease. Therefore, the position of website keywords is very important, which can be explained based on the PageRank algorithm. As the number of articles increases, the link weight of the home page will decrease, The number of links on the internal page is reduced, so the importance of the page is greatly reduced, and the ranking naturally drops.
When diagnosing SEO, it is necessary to check whether the key words of some important positions within the website have changed, which has caused the change of keyword ranking.
3 Relevance of web keywords
The support for links is certainly very important, but only by the support of links, web pages want to get good rankings. Maybe I can't get a better ranking, but the internal relevance is more important to get a good ranking. For example, it is generally impossible to get a good ranking of the keyword "keyword analysis" for a page that introduces the skills of the website's external chain.
