At Ometria all of our features, including website overlay, are built with web performance in mind.
From prototyping the concepts to releasing our features, Ometria’s Engineers are passionate about web performance.
How we built website overlays
Our overlays load after the page has been loaded (after the
Metrics and scoring
The metrics reassured us that the plugin is web performant.
Before loading the overlay
After loading the overlay
We can clearly see that the impact on web performance is minimal.
|First Contentful Paint (FCP)||
Measures how long it takes the browser to render the first piece of content from the DOM.
This is a very important user-centric metric for measuring page load speed. It also provides the first feedback to the user that the page is actually loading.
|Speed Index||Reflects how quickly the visual content is available during page load.|
|Large Contentful Paint (LCP)||
Measures loading performance.
A good user experience would be 2.5 seconds LCP from when the page starts loading.
|Time To Interactive (TTI)||
Measures how long it takes a web page to become interactive.
That point is defined when the page has displayed useful content, the registration of event handlers for the most visible page elements is complete and the page is ready to fully respond to user interactions.
|Total Blocking Time (TBT)||
Reflects the total amount of time between the First Contentful Paint (FCP) and Time To Interactive (TTI) where the main thread was blocked, preventing input responsiveness.
|Cumulative Layout Shift (CLS)||
Measures visual stability.
This is the number of times visible web page elements (fonts, images etc.) changing their position causes a web page layout shift.
