Google has made three significant changes to its AdWords program, according to a post on the company's blog.

Google said it would do away with both the "minimum bid" metric and the "inactive for search" label, meaning that all ads will have the ability to appear for a given set of keywords. The search giant also said it would switch to real-time quality score reports for keywords at the time of a search query.

According to Google, the changes were made to help advertisers refine their keyword campaigns by delivering dynamic insights into performance across factors that include location, the specific query words and relevance.

Google said it would begin rolling out the changes over the next few days.
