In March, Google indexed 3,207,696 pages, but then it dropped off to 1! From March 9 until today, it's only indexing 1 or 2 pages.
Everything in Webmaster Tools says that everything's fine, but there's no explanation of such a major change? The chart shows several years of indexing increasing, then a sudden drop to nothing.
Back in February, I did add a canonical tag, per the discussion and advise in this thread:
[
webmasterworld.com...]
That was about a month before this shift occurred, so the timing is close, but I don't see why it would have had a negative impact. I just checked, and the canonical tags are linking correctly; all they do is remove parameters that Google should have ignored, anyway.
I couldn't find any press releases about Google changing this section, so do you guys have any suggestions on why the sudden change?
