One of a solution to fix the problem "Error establishing a database connection" happens in…
What if I got a Google Adsense crawler errors report?
Today I checked my GA earning, wow, it dropped so bad. How comes? Then I look at the right handside where Scorecard located. Oh no, I got a red symbol at crawler error and my revenue optimization rating was not so good too. After looking looking looking, I found that I have many failed crawling pages but there was one failed crawling page 6 times. That means I have to do something to avoid it; I can’t ignore it anymore. After searching around my site, I could not find anywhere that page is and don’t remember I have ones. Now how do I fix it? No clue.
Thinking thinking thinking… finally, I came up a solution that’s creating a page and named exactly the one failing, for example, if the failing page is http://www.mysite.com/money then I create a page name “money” and make sure the link comes out exactly http://www.mysite.com/money.
However, don’t forget add/write something in that page, don’t ever leave an empty page with Google Adsense there.
Does it work? I don’t know yet. Let see!
