My blog website (Web/PHP Programming Readers Blog) was crawled by the Google search engine around 1 PM.
Two of my articles, "The Differences Between Zend Products (Zend Studio Server, Zend Studio Client, Zend Optimizer, and Zend Platform)" and "A Compilation of Commonly Encountered Issues in Zend Studio," were also written around this time, approximately 1 PM. It was precisely at this moment that the Googlebot came to crawl my site, so these two articles were coincidentally indexed. Among them, the article titled "The Differences Between Zend Products (Zend Studio Server, Zend Studio Client, Zend Optimizer, and Zend Platform)" performed well in rankings for the keyword "zend studio server." ^_^
I don't know what kind of day it was for Google today (August 25, 2008), but I'll remember it. Perhaps in the future, it could be used as a reference for understanding Google's update patterns.
