2.    Do i need to implement all the recommendations ?

No. It's not necessary to implement all the recommendations. But please make sure that you have solid reason for not implementing them.

3.    How many devices and locations you use ?

Right now we check your website speed in desktop, laptop, 6 types of tabs and 6 types of mobiles. We use lots of devices across different locations to provide this service.

4.    Why i need to check performance in different types of devices ?

As you know, your customers use different divices to browse your website and all the devices function differently. So instead of guessing how your website may function in a particular device, it is always better to test it directly on the device and solve any issues you may have.


1.    How your tests are done ?

For each request we open Chrome Web Browser across different devices , clear the cache and then do the tests. We will collect all the data from Chrome, analyze it in our server and then we generate reports.

2.    Do you depend upon any external softwares ?

We use lots of open source and in-house built stuff. Dont worry, all the stuff we use is under our control.

3.    Why its taking long time to get the results ?

We are testing your website in different devices across different locations. This will take time. We are trying our level best to complete the tests as soon as possible. But we also need to wait for the complete website load across all the devices, we can't help if the website takes long time to load.

4.    Are you guys providing API ?

We are working on it. You will hear back from us.
