7. Non-PageRank Factor Threshold)
Apart from PageRank, all other ranking factors have a threshold value, also known as a critical value or a difference value. That is, when a factor increases to a certain value, the importance of the factor gradually decreases, and the value is a non-PageRank factor.
Set the threshold value to 1,000. If page A and page B are the two query results of A certain query condition, and the total score of page A (including page factor score and PageRank score) if the value is 900 and B is 500, it is obvious that A will be at the top of B. However, since the scores of A and B are lower than the non-PageRank factor threshold we have assumed above, without modifying PageRank, we can improve the score of the page factor by carefully optimizing page B to make it rank more than. However, if A's total score is increased to 1,100, B is far from enough to optimize the page factor. In this case, increasing PageRank becomes the top priority.
In general, Google's query result page may contain webpages with scores exceeding the threshold, or webpages with scores lower than the threshold. Therefore:
To improve the competitiveness, you must increase the search engine ranking score of the page as much as possible within the threshold value range. Otherwise, the page competitiveness will be reduced. The "page factor" is the quickest way to approach and reach the threshold value. Its combination with PageRank is the best optimization strategy for improving the website ranking score.
8. Use the threshold value to deduce the value of the two ranking strategies
The missing value explains the principles and implementation approaches that search engine providers follow, and explains why PageRank is misunderstood. We can regard these two strategies as two people A and B.
A thinks "PageRank" is not important. They have several years of experience in web page optimization and know how to use "page factors" perfectly to achieve the goal of optimization. They also understand the basic anchor text, but do not care about PageRank scores. What are the results? Because the "Page factor" is maximized, A quickly reaches the "non-PageRank factor threshold ". Therefore, by carefully selecting keywords, they can obtain better website rankings. In addition, as long as the website content is good, there will always be high-ranking site links over time, and the stream will flow into the river. A finally got the PageRank score, which consolidated the ranking.
B thinks "PageRank" is very important. He has learned a lot about improving PageRank scores and has made enough effort to increase the score. What are the results? B's approach is opposite to A's approach. However, when A does not work on the PageRank factor, the PageRank score is obtained. B worked on the PageRank factor, but the non-PageRank score was obtained. The reason is that the external link is required to increase PageRank score, and the link has an anchor text. Thus, B naturally increases its non-PageRank score by carefully selecting the anchor text of the external link, thus it won a high PageRank score.
