What is your doubt exactly? Is that post count of yours "0". Or am I the only one who see it? Or did the forum forgot to put 1 when you made this post? LOL!
Nice observation, 0getloado I think he means : "Do we need to set a budget every time we create a new ad" (He is an indian. and so am I. So, we have a bond ) No friend. You need to set a budget once per campaign. Yes, if you have only one ad in one campaign, then setup different budgets for each ad. Although its recommended to do the following: 1) Create 1 campaign for 1 product and shortlist important keywords 2) Create groupings of these keywords by relevant and similar keyword terms by creating different ad groups in that campaign. 3) Optimize your landing pages for each ad group 4) Create at least 2 ads per ad group and be sure to set the cpc's as per the keyword requirements. Hope that helps
