Playbuzz saw that content load speeds both on mobile and on desktop should be reduced, and believed this was especially important when their content was embedded on partners’ websites. To address the challenge, the Playbuzz team used both PageSpeed Insights and a Lighthouse audit to derive recommended improvements.

Their subsequent development work involved the implementation of a host of best practices. “We started with a service that served the page on which the item is embedded, continued to create a brand new JavaScript SDK to be embedded on partners’ pages, removed parts of the code that were not in use and, finally, decreased the size of the assets”, explains Playbuzz R&D Team Lead, Nati Levi. “We also dramatically reduced the number of network requests we make by bundling code and CSS, optimised the images by reducing image sizes and implemented a CDN cache on all of our assets.”

On the client side, the team carefully planned the order in which assets should load, moving essential above-the-fold assets to the top and less essential items to the bottom. They also changed their embedding technology from a standard iFrame to an SEO-friendly iFrame, which translated to better search results indexing, more views, more users and better monetisation. For example, the time for appearance in Google’s search results decreased by 40% and the Google referral page loads traffic increased by 770%.

“Our users have a better viewing experience, our publisher partners enjoy more users exposed to their content and our advertisers are able to reach more readers with higher viewability rates.”

Three months after the developments, the results showed roughly a 25% drop in the time required to render a Playbuzz item embedded in a partner page. After further improvements, the drop stabilised at 28%. “This was a significant win for us, as it impacted our entire business”, Nati says. “Our users have a much better viewing and reading experience. Our partner publishers enjoy more users who are being exposed to their content and our advertisers are able to reach more of our readers with much higher viewability rates”, explains Partner and Commercial Marketing Director Aya Mironi.

Playbuzz also managed to cut the bounce rate significantly – by 38% on mobile and by 42% on desktop. And by reducing the size of assets and images, they managed to reduce the bandwidth requirements of their application from 2.3MB to 1.5MB, so users consume less data when viewing Playbuzz items. This change resulted in up to 30% savings in page serving costs.

“Thanks to our partnership with Google and their ongoing support we’re able to provide much better results to our partners”, says Tom Pachys Playbuzz’s co-founder and COO. Looking ahead, the Playbuzz team is focused on keeping page load time top of mind in their future developments.
