On the 26th, the Google servers in the China region began a large-scale data update, which reminded me of someone I met in Guilin recently. He said, "Doesn't Google update every day?" I was speechless at the time — what a genius. Now I'm telling everyone, this is what an update looks like. It will last about two weeks, and the data involved includes multiple aspects, including PR and backlinks.
With the data updated, although I don't care much about these things, there are still people who care more than I do. Several of my friends have been asking me about their website's PR and how it's doing. I checked, and the results are pretty good — they passed. One site has been promoted to PR5, three to PR4, and a few others to PR3. The English sites that were previously subdirectories have now reached PR3. This might be due to the fact that I changed the weight allocation of the sitemap.xml file last time, setting all values to 0.5. Previously, the homepage was set to 1, the rest were 0.5, and further down it was 0.3. Since I've never really cared about PR, I just evenly distributed the weights. Unexpectedly, this unintentional action resulted in these subdirectories gaining PR.
