Assuming you’re not a hands-on graphic designer, you have three good options when it comes to creating Google Display Ads and landing pages:
1. Use Google’s Ad Gallery. Find it by going into an ad group within a Display Network enabled campaign and clicking the blue “+” button. You can use any of Google’s free preset templates and insert your own images and text, or you can use Google’s auto-create feature that automatically generates ads by searching your website and existing Search ads. (The results aren’t always the best looking, but the tool is free, quick and easy.)
