I know this tip has been said time and time again, but I have just had a discussion with 3 people about it so here it is. No. 1 Tip: Use Negative Keywords on Google Ads to target your spend better! If you offer "Glass Door Repairs", you may be getting traffic for "Oven Door Glass Repair". If this is not a service you offer, that is a click paid for that is not generating good traffic. Use Analytics or Google Ads to see the matched search terms over the past week and add any that you don't like to the negative keywords list. You may see less clicks, but they should be better traffic.
