How to reduce costs of paid search campaigns?

Some of the ideas to reduce cost of paid search campaigns are:

• You can A/B test your ad copies and landing pages to find out the best converting ads and pages to get maximum ROI out of your campaigns.

• When using all types of keyword for your campaign, always try and bid highest on the exact match, followed by the phrase, then broad modified and finally broad match. It can help you in decreasing your cost by almost 20%-25%.

• If your business is on a global scale then find the geographies, in the location settings, where your campaign is not converting the visitors into customers as per your expectations and then you can either remove them completely from your campaign locations or put a minimum bid for those locations. Always be location specific when you are a little low on bids and budget.

• You can observe those days in a week, on which your campaigns are not converting and can possibly lower down your bids for those particular days as well.
