If I don't have site map but thinking of placing google adsense on each page would that cause google bot come and index the page?
- You don't need a sitemap to get indexed. If a page can be found through a link, google will eventually find it. - The Google bots and Adsense bots are seperate bots. The Adsense bots will find your page within a few minutes of placing adsense on the page in order to make the ads relevant, but that won't get you indexed into Google's search engine.
The bot will index your site even without a sitemap. The sitemap is not that important when your site is not particularly big and complex. What you have to do to get indexed fast is just to build a few quality backlinks and your site will get indexed in a few days.
