What started as an app created for personal use to identify SEO trends, ended up to be nowadays an essential name in the SEO world and a highly used SEO tool.

The days have passed when SEO should be considered as a separate marketing entity. It doesn’t make sense to learn SEO separately from other marketing activities, and sometimes it is even impossible to do so. Today, a lack of SEO knowledge equals basic illiteracy for any professional marketer.
