Animated Content with Inefficient Formats

Priority: Critical

Impact: Negative

What issues it may cause​

  • Slow Page Rendering: Complex or resource-intensive animations can delay the rendering of page content, leading to a slower user experience.

  • High CPU Usage: Inefficient animations can consume significant CPU resources, particularly on lower-powered devices, leading to poor performance and reduced battery life.

  • Poor Accessibility: Excessive animations or rapid transitions can be disorienting or distracting for users, particularly those with cognitive or visual impairments.

How do you fix it​

  • Convert GIFs to more efficient formats: consider using MPEG4/WebM videos for animations and PNG/WebP for static images.

  • Replicate behaviour of GIFs: replace animated GIFs with video elements (<video>) to maintain autoplay, continuous looping, and silence.

What is the positive impact​

  • Faster Page Load Times: Optimizing animations can reduce the time it takes for a page to become interactive, improving overall page load times.

  • Improved Battery Life: By reducing CPU usage, optimized animations can help extend battery life on mobile devices.

  • Enhanced User Experience: Smoother, more responsive animations can enhance the user experience and make the website feel more polished and professional.

How to fetch the data for this report template​

You will need to run a crawl for report template to generate report. When report has been generated and you have crawl id you can fetch data for the report using the following query:

query GetReportForCrawl($crawlId: ObjectID!, $reportTemplateCode: String!) {
  getCrawl(id: $crawlId) {
    reportsByCode(
      input: {
        reportTypeCodes: Basic
        reportTemplateCodes: [$reportTemplateCode]
      }
    ) {
      rows {
        nodes {
          ... on CrawlSiteSpeedAuditOpportunities {
            opportunityDigest
            element
            title
            auditId
            exampleUrl
            wastedKibAvg
            urlCount
            wastedKibSum
            gaPageviewsSum
            savingsScoreSum
          }
        }
      }
