To rank a website well in Google's search engine, it's essential to have a good Quality Score in our Google AdWords accounts . But what is a Quality Score? How is it measured? How does it affect our accounts? How important is it? Many questions and very few answers. Google has never revealed the secret formula for defining a Quality Score . What we do know is what affects the Quality Score level, and thanks to our experience managing Google AdWords campaigns, we can assure you which variables are important and should be taken into account to optimize our accounts. Before looking at everything we must take into account to achieve a good Quality Score, let's take a look at its importance. With a good Quality Score in our Google AdWords campaigns, we can lower costs per click and also increasingly position our websites in the top positions. A little trick to keep in mind: Every time we create a Google AdWords campaign, our Quality Score level will always start at the highest level. From there, AdWords penalizes us with the Quality Score variants we'll discuss in the next post. Did that seem like too little? Learning marketing takes a day; unfortunately, knowing how to apply and master it takes a lifetime. Philip Kotler.
