When using the Google Page Insights I got a 84 / 100 for user experience.

It gives me the message to check my tab targets.

I got more then 10 messages saying that one target is to close to another one.

In my responsive design for mobile devices I have a hidden sidebar at the left and right that is behind my main content. After swiping to a side a sidebar is shown because of the main content is moved to the left or right.

So all of the targets from these messages are from the sidebars.

Should I pay attention to this or not?

  • Google uses the scoring from that tool to influence search engine rankings for mobile. I don't recall what the cutoff is, but you don't want a low score or Google won't show your site in the mobile results. Oct 4, 2016 at 19:36
  • Yes I know but how can I solve it in my situation? I think many other developers are using the same technic by adding sidebars that are shown when you swipe to the left or right.

For the ones that are interested, I solved it by setting a display: none; on both sidebars ( even when they are overlayed by the main content container ).

Then while swiping, set display to block.

Now the score is 99!

  • I hate that Google uses broken modeling to make decisions about how good or bad your website is. At least in this case they have made a tool that webmasters can use to score their own websites. For most of Google's algorithms we have no insight into the bad decisions their code is making against our sites. Oct 5, 2016 at 15:04
