I have a page which has some mistargeted ads on it. I was going to make a few copy changes to try to get the focus of the adsense ads more in line with what they should be. I understand that it can takes weeks or even months for adsense to spider a page again under normal circumstances. I was wondering how that might be speeded up. For instance, if I drop the adsense code for a day, and then add it to the page again, will the bot come around right then and respider the page?
