Depth decryption Baidu Bidding ranking mode and click Price calculation

Bidding ranking mechanism is the topic that every bidder is extremely concerned about. Baidu bid system upgrade, take the comprehensive ranking index (CRI) as a standard, under normal circumstances, the overall ranking index, the search results page ranked higher.

Is that really true? Do the simplest test, you Baidu input "lose weight", and then you in the Baidu background to promote the live input "lose weight", see the results are not the same. In rare cases, it will be exactly the same, most of the cases are different.

If the ranking mechanism for bidding is the composite index of the quality * bid, then we can predict exactly what position we are bidding on and where. And the fact is, every time we refresh Baidu Search, we see the display results will be in a different way to sort. In other words, we have absolutely no way of predicting where we are before the results of Internet search. And Baidu backstage bidding, to the left side of the keyword display probability, also began to use the probability to hint.

Now we go back to think of a problem, Baidu official explanation two stars will not stabilize on the left to show what is meant, in fact, many Samsung on the left to show instability, if you have a certain number of Samsung words, you can brush their own try. And in some tests, a lot of the words of a star are actually shown on the left. These situations have changed too much compared to the mechanical tutorials in the textbook.

Here I put forward a point of view: Now Baidu ranked system to give a random coefficient of the way, is the netizen in search, according to the quality system given a certain percentage of the left side show, which the quality of * bid has become the impact of this random coefficient of the most important factor. Based on this theory, that is to say, Baidu system in the weakening of the first position of the right to decide the trend, that is, the overall ranking index first is not necessarily ranked first, but the highest probability of ranking first, so we think the Samsung quality bids first will be ranked first recognition is a certain deviation. Baidu used a comprehensive ranking index to determine the random coefficient, take a random algorithm to ensure that those who can not occupy the advantage of the bid also have a certain probability to the front, to obtain marketing results. This should also be Baidu bid to upgrade a trend, is to weaken a little capital discourse right. Therefore, the current ranking mechanism is not guaranteed that you must be ranked first, even if your quality and bid are the first.

If there is a ranking coefficient of random probability impact ranking, according to the tutorial in the click price formula = (next name of the quality * Next bid/your quality) +0.01 billing formula will also be affected, because it may be random to a price and quality is ranked above you under you (this chance is small, but absolutely, You can refresh your industry n times to see the results.

From the actual bid results, samsung keyword Click Price savings and two-star keyword click on the price savings is not so big, just a little bit less money. These and other peers inside some of the results there is a big difference, for the moment cannot estimate Samsung and two stars to the cost of advertising savings to a degree, just know can save. Baidu Background Auction algorithm has been updated, we simply can not accurately detect in accordance with a mechanism for the deduction of the cost of clicks. A specific form for the conclusion of the data report is not listed here.
