Algorithmic pricing means that the prices are adjusted in realtime in response to customer activity and the pricing of other vendors. The goal of algorithmic pricing is to increase profits. Thus,if a few people grab a specific product at a certain price, the price can be raised. Then, prices at other vendors may also increase automatically.
If you know that prices will vary, it might be possible to provide information about what price zones are reasonably competitive for particular products. For example, you might be able to say that Product X is a great product, and 200 is a reasonable price, but if the price goes above 250 it’s suggested to hold off because Product Y becomes more attractive in comparison.
Algorithmic pricing with text mining of sites such as TechTablets could be possible, but I highly doubt it. The algorithm would find it difficult to determine if the sentiment of the review was positive or negative, but purchases are extremely easy to count. I think you are just seeing the price move subsequent to a cluster of purchases near one another (which may have been triggered by a good review).
