How the WordPress Plugin Works

Now that you’ve installed your copy of Optimus Image Optimizer, it will automatically optimize all the images that you upload and use on your WordPress site. What about all the images that you used on your site before installing the plugin? Luckily, you can also optimize them all at once by clicking Optimus Bulk Optimizer across the top of your Optimus Settings page. Also, you can access the same feature if you go to Tools -> Optimize all images.

Optimize All Images

This section allows you to compress all the images that have not yet been compressed in your WordPress media library. You just need to click the Optimize all images button to get the optimization process started. Depending on the size of your images, it can take a while till all your images get optimized.

Green Circles

Now you can go to your Media library – make sure that it’s set to list view – and check the Optimus column for green circles. There is one circle per file. If a circle is missing, the file size was not reduced. If the circle is filled out completely in green, that means all thumbnails as well as the original image have been successfully optimized. If your circle is partially green, not all versions of the image were optimized.



Now let’s take a look at what settings you can configure in the plugin. Though the plugin works out of the box, you still may want to tweak a thing or two.

No Optimization of Original Images

If you don’t want to have your original images optimized, you can go to Optimus under Settings and tick the No optimization of original images checkbox. You’ll want to do this only if you know what you’re doing because your non-optimized images will eventually pile up on the server without being actually used.

No Deletion of Image Metadata

If you want to keep your image metadata, you just need to tick the No deletion of image metadata checkbox. Among other reasons, you want to keep the data so that search engines can make use of EXIF because this format has standard tags for location information (geotags) which may be beneficial for local SEO.

Creation of WebP files

In case you also want to use WebP images, you can tick the Creation of WebP files checkbox. As doing so will slow down the optimization process, it makes sense to enable the feature only if you’re actively using the WebP image file format. Otherwise it’s just downright overkill to switch it on just for the sake of it. Configure responsibly!

HTTPS Connection

If you also want to make sure that your images are safely transferred back and forth, you may want to enable the HTTPS connection feature. Just keep in mind that using it will also slow down the optimization process.

No Optimization of Images During Upload Process

The Optimus Image Optimizer WordPress plugin automatically optimizes your images during the upload process by default. Should you want to disable the functionality, you need to tick the checkbox that is conveniently entitled No optimization of images during the upload process. This allows you to quickly upload unoptimized images to your server if you are in a rush.

You can always go back later and optimize these images when you have more time

You want to keep the highest level of image compression without jeopardizing image quality.

    So at this point search engines are not using EXIF data at all?

    • To the best of my knowledge, they are not, but the data is available in most images on the web and Google is heading for more in-depth analysis and starts taking into account more miniscule details from wherever it can. It’s highly likely that this sort of data will be used before long.

        Never thought of image EXIF info as a part of SEO strategy. Too bad it’s not currently used by the search engines, but I agree that it’s only a matter of time.
        Better get ready in advance.
