Fig. 100 The variation of the amount of the volume with time

From Figure 1 can be seen in the 73-day change in the bamboo fiber net included in the total number of pages increased gradually, presents a "step-shaped" growth model, this growth is also a unique growth model for Baidu, because Baidu generally will have an update time generally in Tuesday or Thursday (in fact, should be Friday, Thursday update but not reflected), Overall, Baidu is included in the stable 100% growth model did not appear a little bit of the downward trend (if cheating may have been k and decline trend), so the summary of the collection of Baidu model:

"Steady growth, step-by-Step growth model"

Fig. 2 The change chart of the amount of Google included with time

From Figure 2 can be seen in the 73-day change in the bamboo fiber net included in the number of pages as a whole is also increasing, but there are a few peaks in the picture, the first one appears in about 21 days, the second occurs around 34 days, and two are in 56 days, and then there is a downward trend after 71 days, A lot of friends used to ask why Google's collection would sometimes grow and fall, this picture can be very good description of this problem, the author analysis of this phenomenon may be because Google included generally faster than Baidu and Baidu frequently, in the beginning of the acquisition of the "swallowed" everything included, And then in turn take a serious look, repeat or similar may be deleted, so that the time when the time is low, but the overall trend is to increase, because your station is constantly updating so there must be new content in the enrichment, so do not worry about such a high and low neuroticism. Summary of the characteristics of Google included

"High time low, overall growth"

Fig. 3 The amount of Yahoo included with time

From Figure 3 can be seen in the 73-day change in the bamboo fiber network included in the number of pages as a whole also showed a gradual increase in the trend, but its growth model is somewhat similar to Google's, but the difference is that Yahoo is more cautious in its 73-day change to <250 and Google's number is <1500. So the summary of Yahoo's collection model is: "When the low, overall growth, follow"

Figure 400 Degree reverse connection number with time change chart

From Figure 4 you can see in the 73-day change in the bamboo fiber net Reverse Link number overall also into a step-type growth in 46 days before and after the emergence of an underestimate, this may be my use of the query tools included in the question, and Baidu is not included in the number of pages, put aside this map from Baidu's reverse link results can be analyzed, Baidu's direction link overall quality is not high no good reference.

Figure 5 Yahoo Reverse link Change chart

From Figure 5 can be seen in the 73-day change in the bamboo fiber net reverse link number, the rendering curve is increasing, its reverse link can be more referential than Baidu quality.

Summary: Summing up the above Baidu Google Yahoo and Baidu Yahoo's direction link to the situation can reflect the bamboo fiber network (bamboofiber.org/bamboo Fiber. NET) in 73 days a total collection and reverse link number changes, can also see Baidu Google Yahoo in the collection mode and Baidu Yahoo in the reverse link included a feature, generally speaking, Baidu is conservative and stable Chinese image, step conscientiously seriously, Google is extroverted sexual character, first warm received in earnest inspection you, And Yahoo is cautious a bit feminine temperament characteristic is conservative cautious.
