Critical recommendations for keywords of Google Adwords then use them for some time, you can check the keywords click-through rates and delete effective combinations of keywords. Always use the negative keywords feature. For example, if someone uses the free search term poster art, then you should use the free in the corresponding field of Google AdWords and consequently negative keyword keyword. The art of the poster will not be displayed. To do this, you will prevent promotion gift-seekers that are not targeted to their offer, and as a result will improve their percentages of clicks and will reduce the cost of their campaigns. It can also use similar negative words that refer to the cost such as: no cost artworks art and so on.
The creation of a group of keywords has an effective time limit. Although there is no specific rule about how many keywords should be used, follow the recommendations of Google in the amount of keywords. Google recommends: a maximum of 100 ad groups per campaign and 750 words per ad group. Many people lose money because of that reason. If you have for example a cooking school in Medellin, it is obvious that the people of Barranquilla will not be interested in his services. So show a general term like cooking or even kitchen training centre; your ad in Google Adwords will display and prospects in the interest of its offer will be reflected in the clicks at an additional cost to their campaigns. This will be transformed into opportunities. Reference:
