What's the impact on SEO from having an 'Estimated read time' in the SERP?

Early this year we noticed Google was scraping the ‘Estimated read time’ from some blog post pages into their meta descriptions. We wanted to know if that had any benefit to organic traffic, so we tested manually adding it to the front of the meta descriptions on an ecommerce customer’s blog pages.

We ran a title tag test with a customer in the listings space on their search results pages. Our customer had the current month and year in the title tag to indicate freshness, but actually updates their listings more frequently than once a month - they update them daily. We wanted to test if putting “Updated Daily” instead would improve organic traffic.

Here’s what they thought: The largest proportion opted for positive, but it’s fair to say that opinion was evenly split between all three options - there was no intuitive feel among the community for how this test would go. In situations like this, testing is extremely useful so that we know the true impact of a change rather than guessing.
