I am using
google webmaster to monitor maintain my site regarding SEO aspects. My site suffered a huge amount of index drop during last few months.
I understand why I am loosing indexed pages and it is not the problem I have now. In the google index status chart, I noticed I had the same number of pages indexed for passed 5 weeks. We came to the conclusion that the drop is stabilized now.
But on a recent day It seems google have updated all 5 of index status points in the graph. You can observe that not a one point but several points are updated.
How is this possible? Does google do this more often? Is it risky to take decitions by looking at google index status chart as they update several (5 here) history points in the chart?
Note : I have observed google updating the latest previous update before. But this seems different.
