1. Change your Bid amount. The amount you bid is always proportional to the clicks. If you are low on the page, you won’t get clicked on as much. If the bid amounts are too high for your budget, then get rid of underperforming keyword phrases or ones off topic.
2. Write more ads. Try out new things. This is trial and error, but an effective ad can increase clicks by a lot. Something eye-catching and impressive is always good.
3. Target more niche phrases. Try to target more odd search phrases that would give you a chance to rank higher for less money. Don’t compete on volume keyword phrases unless they are performing and you have the budget.
