There are a few ways you can increase traffic.
1.) Increasing position. Obvious, but moving up to an average position of 3 will get you into most of Google’s Syndicated Network. If you are in positions 4-6 you might want to consider moving up to position 3. Once in position three you will start to be syndicated and get more impressions.
2.) Copy Testing. Test using new copies that have different call-outs than your competitors. If you have a free product/service, call it out. Use ALL Caps on the first letter of each word in your ad. Use the one alloted exclamation point. If you have a Patent Registered/TM use those unique characters in your ad. (R) or TM. To get an additional line of space you can sign up for Google Check-out. Or set-up a geo-targeted account that will add a line under your add to call out the geo-targeted area. Try adding the product/service to the Domain in your ad. I.E.) www.freeforums.com/adwordshelp. This can give you another keyword or two to be bolded.
3.) Turn on the content network. Be very careful with because of the number of impressions and clicks you might get. This users are not searching for your product or services so the Conversion Rate tends to be much lower.
4.) Open up the search traffic to other countries. Be careful with this because of click fraud issues and not giving the user the best experience by landing them on an english only site.
