Ad groups allow for each campaign to be further subcategorized for relevance. In our hardware store example, one ad group could be for different types of rakes or varying models of leaf blowers. For the power tools campaign, one ad group might focus on power drills, while another could focus on circular saws. This level of organization might take slightly longer to set up initially, but the rewards – namely higher CTRs at lower cost – make this effort worthwhile in the long run.
Search Engine Optimization (SEO): Maximizes search result exposure by targeting and driving Web traffic and ultimately delivering increased sales. The majority of search engine page results come from unpaid or organic search. SEO optimizes websites to ensure top search engine placement, such as Google, as only 15 percent of searchers continue beyond page one.
Because so few ordinary users (38% according to Pew Research Center) realized that many of the highest placed "results" on search engine results pages (SERPs) were ads, the search engine optimization industry began to distinguish between ads and natural results. The perspective among general users was that all results were, in fact, "results." So the qualifier "organic" was invented to distinguish non-ad search results from ads.
Remember when you used to rely solely on search engines for traffic? Remember when you worked on SEO and lived and died by your placement in Google? Were you #1? Assured success. Well, okay, maybe not assured. Success only came if the keywords were relevant to your site users, but it was the only real roadmap to generating site traffic and revenue.
