The search impressions your website receives for a specific keyword or phrase has a huge impact on your site's ability to gain traffic. Many site owners think that ranking for a keyword will guarantee visits, but this is not the case. Search impressions guarantee visits. Each time your webpage is displayed in a Google search or an advertising rotation, this is called a search impression. When someone speaks of a search impression they are usually talking about pay-per-click advertising or other types of search engine marketing. The goal for advertisers is to get the maximum number of impressions for the lowest cost. More impressions means more clicks. The ratio between the two is impossible to deny. So, what would be defined as a good number of search impressions relative to the amount of money you are having to spend on advertising? It depends. The first thing that has to be considered is search volume for your targeted keyword. Keywords that receive a large search volume won't always produce a large number of impressions. The competition is just too strong. Everyone is vying for impressions on a popular keyword, and this makes bidding for impressions far more expensive and difficult. Low-volume keywords will tend to produce a higher number of search impressions, but this doesn't always mean that those impressions will translate to clicks. Why? Because sometimes keywords with a low volume of searches are merely long-tailed funnels to a more popular keyword. The bottom line is that there is no way to quantify what constitutes a good number of search impressions. Search engine marketing is a relative endeavor. More impressions are related to more clicks. All you must really understand is that a higher number of search impressions is better than a scattered few. Getting a lot of impressions with your ad campaigns means that you have targeted well. Rather than trying to define what a good number of impressions is, you should always be tweaking your campaigns to get a larger number of impressions.
