Google seems to be expanding their reminders to alert webmasters about the new mobile friendly algo that was launched last week. While we have seen reminders within Google Webmaster Tools, they have added a new alert at the top of the Google AdSense login page to alert any publishers about the mobile friendly algo in case they happened to miss the news.
The link leads to a page in the AdSense support section detailing the mobile friendly algo and how webmasters can ensure their sites will get the mobile friendly boost.
While it is hard to believe some webmasters might not have heard about the mobile friendly algo, particularly with all the mainstream publicity about it, it is nice to see Google trying to ensure as many webmasters are aware of the new algo as possible.
