Hi, I had AdSense on one of my sites a while back. I took it off. Now, I put the AdSense codes back in. Do I need to do anything or should I just want for Google to crawl mysite in order to restart the AdSense? I am new to this. Thanks in advance for your help!
Just wait an hour or so. In most cases it doesn't even take that long. Your ads will start showing shortly.
just open the pages that have adsense on them and the adsense bot will crawl them quite quickly. When the googlebot visits is another story.
visit your pages one time and adsense bot will crawl your site again. you have started the adsense again. that's all
If you have thousands of pages, don't bother opening them. If your site is popular anyway the adsense bot will crawl that page after the 1st or 2nd visit from your vistors anyway.
