These ads, often known by the term pay-per-click ads, come in a variety of formats. Some are small, text-based ads, whereas others, such as product listing ads are more visual, product-based advertisements that allow consumers to see important information at-a-glance, such as price and reviews.

Benefits of Search Engine Marketing (SEM)

Search engine marketing SEM’s greatest strength is that it offers advertisers the opportunity to put their ads in front of motivated customers who are ready to buy at the precise moment they’re ready to make a purchase.

Websites that rank on the top of search engine result pages (SERPs) with organic results for their target keywords, can get free traffic continuously unless it’s crawlers blocked by the user or content owner for a certain reason like content moved, deleted, or unavailable.

Websites that use paid advertising methods like PPC which is can still get targeted traffic from search engines, but they have to pay for it. Once they stop the paid campaigns, the traffic disappears.

Another major difference between SEO and SEM is that the search engine optimization process takes a lot of time to work and generate results while increasing visitors to a specific website through PPC is almost instant.
