Welcome to WebmasterWorld Guest from 220.127.116.11
So, the first time a page is accessed, Adsense will serve third part ad network ads at best, or blank/backup ads. Then, "sometimes" later, the Adsense bot will come fetch the page, and if it's okay, then the next visitors will see Adsense' ads. It doesn't seem to be only a one time check. Some (like myself), noticed that the process seems to repeat every 2 weeks. (it's sure that the content of a page can change over the time).
I have an on-site search which reindexes every 72 hours & I see no helpful affect.
This did put the ads back after a few minutes, but no longer seems to have any affect either.
The number of impressions resulting from this crawling will likely be very high, again resulting in the request being ignored (best case scenario) or your account being banned for artificially inflating impressions.
I had to dig deep and apparently Google is mad at the election, I don't follow politics or vote, but from what I read they started doing this because of the election.
They keep changing the algorithm and ruining search, all because the people in that department don't want to be laid off /.../ all they had to do was get rid of spam sites which are easy as hell to spot.
I just checked again still no adverts, and my article is getting some good traffic, It was about a local tennis event took me 3 days to write up, I posted pictures I took from the event and some interviews now all that work down the drain.
Last week I noticed some spammer stole my entire article, I did a title search he stole it and just spun a couple of words it wasnt even coherent and outranked me, how do you guys keep going, its like a losing battler when the bad guys keep winning and the honest bloggers suffer.
Is media.net any good as an option because Adsense is lacking
