When a search engine user in the targeted area searches for the keywords or keyphrases that you chose, your ad enters an immediate online auction. Your ad is displayed when it matches bid and relevancy criteria, so you want to make sure that you have an appropriate budget size, and that you are bidding on keyphrases relevant to your products/services (such as those indicated on your website or landing page). You are not charged when your ad is displayed, but rather when someone clicks on your ad to take further action.
RankBrain can have an impact on your keywords campaigns. When you are defining your keywords, you are looking for relevant terms that respond to customers queries. This is how a successful SEO strategy works. And logically, if you are picking keywords your audience is not searching for, you campaign will have no chance to succeed. This is where RankBrain can play a role.
Clients turn to search engines because they really need a product or service. They have already created a need; it only remains to find a company that suits their interests. It is a medium that can easily encourage conversion, if the company offers what the customer is looking for; the visit will result in action by the customer, either a direct purchase, request for a quote, or more information for a later purchase.

So if you're in the local space and you're saying, "Gosh, Google has really taken away the ability for my website to get the clicks that it used to get from Google local searches," going into Google My Business and optimizing to provide information such that people who perform that query will be satisfied by Google's result, yes, they won't get to your website, but they will still come to your business, because you've optimized the content such that Google is showing, through Google My Business, such that those searchers want to engage with you. I think this sometimes gets lost in the SEO battle. We're trying so hard to earn the click to our site that we're forgetting that a lot of search experience ends right at the SERP itself, and we can optimize there too.
At our agency, we work with sites of varying sizes, from very large to quite small, and recently, we have noticed a trend at the enterprise level. These sites aren’t relying as much on Google for traffic any more. Not only are they not relying on Google traffic, but also, the sites are getting less than 10 percent (or slightly more) of their organic traffic from the search giant.
