Last night, John Mueller did a hangout at the GooglePlex and Martin Splitt from the Webmaster Trends Analyst team was with him who was able to answer some really technical JavaScript questions. This one was about lazy loading scroll events and how Google handles them. With it, he brought up on topics on GoogleBot scrolling and the use of the noscript tag.

In short, Martin Splitt explained that they are working on new documentation around how Google handles lazy loading scroll events with JavaScript in search. I suspect this new documentation is being worked on because I really gave Google a hard time about the confusion around communication between John and Gary on these two topics linked above, i.e. does GoogleBot scrolling and the use of the noscript tag.

In short, Martin said GoogleBot does not scroll but said GoogleBot is doing “something slightly different.” He also said for these elements, Google will read and use the noscript tag. So maybe both Gary and John were both right?

Let me share the transcript, because Martin goes through three reasons why lazy loading scrolling might not be a good idea:

Here is the transcript:

In short, if you need to use it now, do dynamic rendering or wait for the new Google docs on this.
