A billion-dollar global information and publishing company noticed a heavy decline in natural search traffic for a specific segment of its business. Greenlane Search Marketing, LLC was engaged to identify the problem and provide solutions.

Solution

Greenlane performed a detailed crawl of the site to locate over 80 duplicate pages for each key landing page – some of which Google indexed, while others were appropriately filtered out. We identified and removed millions of pages of varying quality.

Result

Within the first day of making the changes live, Google took notice, and the crawl budget quickly rose thereafter. Google was not only enjoying a better use of PageRank for ranking but also discovering more unique buried content.

Challenge

A Philadelphia-based athletic cover manufacturer partnered with Greenlane to assess its website after a re-platform and redesign. The company faced low, inconsistent online traffic on key product pages. Our team found duplicative content causing internal competition and pages with minimal info.

Solution

Our goal was to boost website traffic and engagement on key e-commerce pages lacking strong content and SEO tactics. Enhancing the overall buyer’s journey was crucial, as supportive resources were hard to find, missing opportunities to educate shoppers and showcase robust content for search engines.

Result

Strategic advisement and execution led to a 155% increase in engagement rate for the cover manufacturer, from 34.6% in Feb 2023 to 88.3% in Feb 2024. Product pages saw a 40% lift in sessions, a 44.7% rise in new users, and a 125% boost in views. Content & SEO optimization were key to these results.
