Keyword research tells you what topics people care about and, assuming you use the right SEO tool, how popular those topics actually are among your audience. The operative term here is topics -- by researching keywords that are getting a high volume of searches per month, you can identify and sort your content into topics that you want to create content on. Then, you can use these topics to dictate which keywords you look for and target.
Search engine marketing (SEM) is related to SEO in that they both deal with digital marketing outreach on search engines like Google and Bing. However, SEO typically refers to internal, organic website optimization while search engine marketing is commonly known as advertising through a paid media budget. While SEO will help your website traffic increase through natural algorithmic means, SEM earns traffic through the process of purchasing ads on search engines. In the image to the left, you will see a search engine results page that is the result of typing the keyword “digital marketing” into Google. The top four results have a small green box that says “ad” underneath the primary title link. This signifies paid advertising, or search engine marketing, where a brand or business has paid Google to display their ads at the top of the page for that specific keyword.
The impact of SEM is immediate. SEO takes time. Through paid SEM ads, you can start to put your results in front of audiences with just a few clicks. As soon as you launch a campaign, your ads start showing in SERPs. At any time, you can turn ads on to increase visibility or turn them off to stop showing. Conversely, SEO is something that you acquire over time and typically over a long time. It can take months of implementing an SEO strategy before a brand begins to rank on search engines.
Online reviews, then, have become another form of internet marketing that small businesses can't afford to ignore. While many small businesses think that they can't do anything about online reviews, that's not true. Just by actively encouraging customers to post reviews about their experience small businesses can weight online reviews positively. Sixty-eight percent of consumers left a local business review when asked. So assuming a business's products or services are not subpar, unfair negative reviews will get buried by reviews by happier customers.
Google Ads (formerly Google Adwords) is the search provider most commonly used for this strategy. With this tactic, brands conduct keyword research and create campaigns that target the best keywords for their industry, products, or services. When users search for those keywords, they see the custom ads at the top or bottom of SERPs. The brand is charged each time a user clicks on the ad.
