Can improving freshness signals in titles benefit SEO?

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.

Can emojis in title tags be beneficial for SEO?

In this week’s #SPQuiz on Twitter, we asked our followers what they thought would happen when we added emojis to title tags for thematic content pages. 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.
