Dive Brief: 

• Small-to-medium sized business are wasting 25% of their spend on Google AdWords, according to a study from Wordstream. 
• Wordstream says the biggest problem among SMBs is they only tweak their keywords every 90 days, leaving a lot of missed opportunities. 
• The study also found that 95% of SMBs did not have a click-to-call button on their Google search ads, meaning they are losing out on numerous phone leads. 

Dive Insight: 

It's not surprising that small businesses are missing out on opportunities when it comes to search. The practice of search and AdWords is more time consuming and complicated than it appears, and SMBs often just don't have the resources. WordStream Chief Tech Officer Larry Kim makes the suggestion that SMBs should spend 20 minutes a week on optimizing their AdWords accounts. That is a helpful tip that sounds easy enough, but could be difficult for many time-strapped SMBs.
