We swapped over to Domain Validated on nearly all our properties, so the Crawl Budget information is no longer available
Our sitemaps however look to be "last read" anywhere from 3-8 days ago, depending on the site. Even though there's new content, it's still taking 3+ days to actually crawl and index.
On one of our sites we saw a big drop in the number of pages indexed (went from 423 on 8/1 to 195 on 9/1. So that raised some alarms, but the impressions remained about the same.
On 10/1 we saw the number of pages indexed at 196 (even though there were 4 new posts, older ones were dropped), but our impressions went from 1201 daily impressions to now a solid 2500 impressions.
No changes in the number of pages on the site, only 4 new posts added, but that's a big change for impressions.
We're seeing about a 30% increase on impressions on a number of properties comparing September1 to October 1. Something appears to have changed with indexing and dropping of older content - but the impressions are going higher.
We've always talked about curating content and either removing or updating older posts and pages, but with this shift, we're seeing huge changes. We also saw huge changes when it came to the number of keywords indexed with roughly 50% of the keywords still in the top 100 positions - but upon review, the ones that were dropped were useless and not driving traffic anyway.
So something is up with indexing and rankings for sure - but hard to pinpoint as to what other than Google Algorithm
