The Google Search Network refers to the Google search results page (SERP), as well as Google search sites and other search sites who partner with Google to show ads. The latter are commonly referred to as ‘search partners’ or the ‘search network’ (one well known example is AOL).
Search results are generated as they match to the terms a person is searching on. By and large the accepted format for ad placements here are text based and generated by the keywords that are chosen to populate the campaign.
Research shows that nearly 6 out of 10 people initiate their product search using a search engine. Google maintains a month over month market share which exceeds 80% on a continuous basis. Therefore when you advertise through Google, you have net access to 80% of the 6 out of 10 people who are launching a search for the products or services that you offer.
When you target your campaign to the search network and add keywords to your campaign’s ad groups, your ads can appear on Google and other search sites based on the keywords you have chosen.
On Google search sites, your ads will appear above, alongside or below search results. On the search network, the results will appear in very similar locations.
