Different sizes

As you know, light-weight ads are our thing. There are two important sizes about your ad files that you should understand:

  • Initial load size - the size of files to complete the first display of the ad (usually splash). This is an indicator of how fast your ad might load if the user has a slow internet connection.
  • Total load size - initial load size plus the size of all asset files, including videos and images that load after interaction. This will help you understand how much of overall internet bandwidth the ad is using. Publishers have different rules on how large files can be, so be sure to know your limits.

We comply with industry standards and use the same definitions as in IAB New Ad Portfolio (respectively initial file load and user-initiated load). Your goal should be to keep these numbers as low as possible without sacrificing good image/video quality.

Automatic optimization

We have a proprietary AI algorithm to optimize assets. We optimize automatically when you upload or drag an asset to specific asset slot. Main assets and overlays have different default optimization levels. We keep the overlays a bit better quality as they are mostly company/product logo, and CTA buttons or social media icons that needs to clear and crispy. Nobody likes a blurry logo or a call to action that's difficult to read.

When to use asset optimization?

In most cases we nail the optimization, but in the unlikely event that we need to manually adjust something, you can. You may want to:

  • keep logos/CTAs with higher quality
  • use a lower quality for background assets
  • balance ad load size and asset quality. This is especially important when publishing on Google Ads

Please bear in mind that:

  • optimizing less results in a larger load size (ie - longer load time for ad viewer)
  • optimizing more results in less clear images (ie - can look look unprofessional for ad viewer)

Both of these could also lower your campaign performance.

How to use asset optimization?

For every asset, there's "Change optimization" icon:

This opens up a modal where you do the magic:

Use the "Optimize more" or "Optimize less" buttons to see real-time results of your optimized asset. Drag the slider to compare the original and optimized assets. When the optimized size and quality looks how you want, then click "Save".

Pro tip

You can use SVG assets in creatives. SVG is a vector image format that can be scaled up or down to any resolution, with no change in quality. You can upload or drag an SVG asset into any asset slot, and use the cropping tool to scale and position it. When done right (by a designer), they are also extra small files compared to JPG or PNG. For comparison:

Bonus

Also, we have a standalone service called Nexd Asset Optimizer. You can open it from Campaign Manager from the menu:

The user interface for optimization is the same. The main difference is that Asset Optimizer is not connected to specific creative, so you can just optimize a single image asset, multiple video assets, or even an HTML5 zip. You download the optimized file, and can insert it into your creative, or use it anywhere else!
