Google is constantly making changes to its search algorithms, which can have a negative impact on your site’s visibility or provide a unique opportunity to rise above the crowd.
HubSpot’s traffic increased by 107% after the company adjusted to one of Google’s most recent major algorithm updates.
How?
Google has been making strides to incentivize content creators who group related topics together. This means that Google now evaluates the entire body of work coming from a given URL rather than just a single post, sending more traffic to those who appear to be authorities on a given topic.
Therefore, you have a great chance of doubling your organic traffic if you narrow your coverage to a single topic.
An existing multi-topic blog can benefit from splitting into topic-specific websites with 301 redirects from older posts.
