REMINDER: You are reading the last episode of GWMT series.
I'm not gonna talk in detail about these features, as I already have older posts related to some features we gonna discuss here. Hence, this post will be shorter than previous posts. But I'm walking you through the features available under Labs right now.
But due to low usage of Instant Preview feature, Google dropped it lately and you can find instant previews are no longer available on Google search.
Site performance is another helpful feature which analyzes your site and report loading time for your blog or website.
Unfortunately, it's no longer supported on GWMT. Instead, you can use Google PageSpeed to analyze and find how you can improve overall site performance.
