Google has published the first in what will be a series of blog posts dedicated to SEO case studies.

The aim of this series is to share success stories that demonstrate the value of SEO.

Google says the intended audience for these case studies are people who may need some extra convincing that SEO is a good investment.

“We want people to hear about these success stories, so we’re starting a new blog post series that features case studies. They may, for example, help with convincing a boss’ boss that investing in SEO or implementing structured data can be good for the business.”

Google’s inaugural blog post in this series focuses on the basics of investing in SEO and how it has been utilized to help a company.

Early Success With Google Search Console

Saramin’s SEO efforts date back to 2015 using nothing but Google Search Console.

An entire year was dedicated to finding and fixing crawling errors identified by Search Console.

This alone lead to a 15% increase in organic search traffic.

Satisfied with their early success, Saramin decided to invest more into SEO.

Gradual Changes for Big Gains

The next step in the process was studying the Google Search developer’s guide and help center articles.

Illyes acknowledges that “SEO is a process that may take time to bear fruit.”

To that end, Saramin focused on implementing gradual changes such as:

Removing poorly written and unhelpful meta tags.

Using rel-canonical and removing duplicate content.

Applying applicable structured data.

This process of making these changes also involved the use of additional Google tools.

Saramin relied on the Structured Data Testing Tool, Mobile Friendly Test, AMP Test, and PageSpeed Insights.

Eventually, the errors in Search Console’s Index Coverage report turned from red to green.

Even more than, Saramin saw an accelerated increase in organic traffic.

“The incremental changes reached a tipping point and the traffic continued to rise at a more remarkable speed. In the peak hiring season of September 2019, traffic doubled compared to the previous year.“

The Results

Along with the increase in organic traffic, the quality of traffic also went up.

Saramin achieved a 93% increase in the number of new sign ups and a 9% increase in conversions.

The work doesn’t end there, however, as Saramin’s SEO manager says “this is only the beginning of our story.”
