How much you spend on your ads campaign is very important. The data which is collected through your ads campaign allows you to best manage that budget. Remember depending on your market, competition, keywords and phrases you wish to target, this will have a direct affect on how much you will be charged per click. Additionally refining what words and phrases to omit from your campaign, showing your ads to selective locations at selective times will help you to best spend the budget.
Once enough data is collected and the above has been analysed, this is when you should increase your spend, as you are primed to have your ads seen by only those who need to see it. Unfortunately the sad truth of the story for many website owners is, at this stage they may feel as though the campaign is not working and look to swap provider or give up with ads altogether. Unfortunately, it puts them in a cycle doomed to repeat the same steps again.
So firstly i would say, as a website owner, get a general understanding of the process. Which if your reading this, your off to a good start. Secondly, build a good relationship with the business who is providing the service, as you don’t just want to be a figure on there bank balance, but an individual who’s needs really matter.
