About this SEO factor:
GZIP is a generic compressor that can be applied to any stream of bytes: under the hood it remembers some of the previously seen content and attempts to find and replace duplicate data fragments in an efficient way - for the curious, great low-level explanation of GZIP. However, in practice, GZIP performs best on text-based content, often achieving compression rates of as high as 70-90% for larger files, whereas running GZIP on assets that are already compressed via alternative algorithms (e.g. most image formats) yields little to no improvement. It is also recommended that, GZIP compressed size should be <=33 KB

Title Icon Descriptions
WordPress
server-response-timeThemes, plugins, and server specifications all contribute to server response time. Consider finding a more optimized theme, carefully selecting an optimization plugin, and/or upgrading your server.
render-blocking-resourcesThere are a number of WordPress plugins that can help you [inline critical assets] or [defer less important resources]. Beware that optimizations provided by these plugins may break features of your theme or plugins, so you will likely need to make code changes.
efficient-animated-contentConsider uploading your GIF to a service which will make it available to embed as an HTML5 video.
unused-javascriptConsider reducing, or switching, the number of [WordPress plugins] loading unused JavaScript in your page. To identify plugins that are adding extraneous JS, try running [code coverage] in Chrome DevTools. You can identify the theme/plugin responsible from the URL of the script. Look out for plugins that have many scripts in the list which have a lot of red in code coverage. A plugin should only enqueue a script if it is actually used on the page.
modern-image-formatsConsider using the [Performance Lab] plugin to automatically convert your uploaded JPEG images into WebP, wherever supported.
uses-text-compressionYou can enable text compression in your web server configuration.
uses-responsive-imagesUpload images directly through the [media library] to ensure that the required image sizes are available, and then insert them from the media library or use the image widget to ensure the optimal image sizes are used . Avoid using `Full Size` images unless the dimensions are adequate for their usage. [Learn More].
unused-css-rulesConsider reducing, or switching, the number of [WordPress plugins] loading unused CSS in your page. To identify plugins that are adding extraneous CSS, try running [code coverage] in Chrome DevTools. You can identify the theme/plugin responsible from the URL of the stylesheet. Look out for plugins that have many stylesheets in the list which have a lot of red in code coverage. A plugin should only enqueue a stylesheet if it is actually used on the page.
uses-long-cache-ttlRead about [Browser Caching in WordPress].
offscreen-imagesInstall a [lazy-load WordPress plugin] that provides the ability to defer any offscreen images, or switch to a theme that provides that functionality. Also consider using [the AMP plugin].
uses-optimized-imagesConsider using an [image optimization WordPress plugin] that compresses your images while retaining quality.
unminified-javascriptA number of [WordPress plugins] can speed up your site by concatenating, minifying, and compressing your scripts. You may also want to use a build process to do this minification up front if possible.
unminified-cssA number of [WordPress plugins] can speed up your site by concatenating, minifying, and compressing your styles. You may also want to use a build process to do this minification up-front if possible.
total-byte-weightConsider showing excerpts in your post lists , reducing the number of posts shown on a given page, breaking your long posts into multiple pages, or using a plugin to lazy-load comments.
