RebelMouse Announces Platform Wide Support for Next-Gen Images

At the start of 2019, we announced that performance would be our top priority of the year. At RebelMouse, we're traffic junkies that work every day to make sure our clients have the best-performing sites on the open web, often beating out industry giants on speed.

Our latest upgrade takes this mission one step further. We've switched to Google's WebP for image formatting and resizing. This means we'll be converting all GIF, JPEG, and PNG images to Google's next-generation image format.

According to Google, WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are also 25–34% smaller than comparable JPEG images. For more information on the new format, click here.

Here's how a page that's not using WebP images performs according to Google's PageSpeed Insights tool:

As you can see, common image formats return a number of penalties. By contrast, here's how a page performs when it uses Google's next-generation image format:

In these results, the only penalties that result are from the logo, ads, and Amazon assets embedded in the article. By using WebP, we're able to shave valuable seconds off the load time.

This change applies to all posts created on your site, not just going forward. Please take into account that it does not automatically convert assets that are or were uploaded in our Layout & Design tool (like your site's logo, for example).

For browsers that don't support WebP, we fall back to non-next-gen image file types.

We've been slowly rolling out this new format per client while closely monitoring performance and analytics along the way.

Please contact your account manager if you have any questions about this new feature or if you'd like it activated for your account.

NEW! Beta Posts Dashboard: Filtering and Search UI Upgrade

New Filters in Posts Dashboard

We've implemented new filters that allow users to easily find exactly what they need in their posts dashboard. You can now customize your search results by:

  • Creators You Follow
  • Rating
  • Post Status
  • Post Type
  • Period
  • Sections
Here's what the new filter menu looks like:

Easy-to-Use Search Queries

In the same slick user interface, you can also create search queries and combine them with your filtered results:

  • Post Search
  • Creator Search With Ajax Autocomplete
  • Community Search

This is an exciting step forward in enhancing the editorial experience for our users. It should now be much simpler to narrow down results to exactly what you're looking for.

Here's how the workflow looks in action:
