Compare the performance of both your own and your competitors web pages. Easily visualize the gaps between several web pages using the various performance indicators, page weight and the number of requests.
Use the comparison feature to:
- create a comparison report between two web pages (same of different websites)
- compare existing standalone reports (e.g. Before and after optimization)
- replay simultaneously the videos related to the tested pages and compare their filmstrips.
Note: If you choose to compare more than two web pages, the retest and download report option will not be available. (You can still share the online version of the reports).
Compare existing executed reports
1. Once you have run multiple tests, go to the reports tab to see the full list of reports that have been executed.
2. Check the boxes of the reports you'd like to compare (compare up to 12)
3. Select 'Compare'
Create a comparison analysis
1. Go to the 'Compare' tab
2. Select the type of comparison analysis you'd like to create (see below for more details on the comparison types)
3. Complete the form details as required
4. Select 'Compare'
Comparison reports that you generate will be stored and can be accessed in the Comparison reports tab from the Reports menu.
Comparison analysis types
- Competitive comparison: Compare two different URLs to generate a comparison report between the two pages based on 2 Speed Analysis Lab analyses executed according to the very same test settings. Choose between mobile or desktop tests and select the location from which the two tests have to be executed
- Mobile vs Desktop: Compare the web performance between the desktop and mobile version of a single webpage
- Cache testing (1st vs 2nd visit): This report compares the web performance of a single page with a first and second visit to measure the efficiency of the browser cache. (The second display should be faster)
- Advanced comparison: Compare the same page or two different pages based on the complexity of contexts required
Using the Comparison Report
Once you have launched your comparison analysis, the report will be stored in the reports tab and will also be available in your dashboard, in the section 'Comparison reports'.
