Search Engine Marketing (SEM) Opportunities for siom.ac.cnQueries that provide opportunities for this site to advertise through Search Engine Marketing (SEM) to get more traffic. They are popular queries that are relevant to the site, and have low competition in search engine marketing. Learn More Many sites are actively advertising in search engines for the most valuable search queries. This high level of competition tends to result in high advertising costs, which makes it difficult to find attractive advertising opportunities. These opportunities may still exist, however, by looking at the "long tail". The long tail contains search queries with lower Query Popularity, but such queries also tend to have lower QCI.
