Databases - Global Premium
Skew is a major problem that has traditionally faced all keyword suggestion services. Typically search statistics reported on popular queries are impacted by various automated agents such as search engine crawlers, rank and bid checkers. These inflate the true search numbers making it difficult to accurately estimate available traffic.
To overcome this problem, the Global Premium database contains over 4.4 billion keyword searches based purely on user panel data. This data is is less prone to skew caused by automated agents.
The Global Premium Database is the default database and can be changed by selecting another database from the "Database" drop-down menu on the search form.
Keyword Discovery is currently the only keyword research service with this level of data quality.
Below is an example on the search term "ipod" from both our Global Premium and Historical Global databases.
