Back in March, Google informed us that they were getting ready to boost the mobile friendly algorithm for May and it looks as though the rolling out has been completed. This boost is believed to increase rankings for mobile friendly websites in mobile search results.
For those unsure of what this algorithm is, it basically states that your website would be moved down in mobile search results if it wasn’t mobile friendly for users on their mobile devices. If your website is already mobile friendly, you won’t be affected by this algorithm update so there’s no need to worry. If you’re unsure whether or not your website is mobile friendly, test it here.
