With concerns to the modifications made to seo, for material publishers and authors, Hummingbird is planned to solve issues by getting rid of unimportant content and spam, allowing Google to produce premium content and rely on them to be 'trusted' authors. What Is Local.

In December 2019, Google started upgrading the User-Agent string of their spider to reflect the newest Chrome version used by their rendering service. The delay was to allow web designers time to upgrade their code that responded to specific bot User-Agent strings. Google ran evaluations and felt great the impact would be small.
