Google announced that the page load time metric is now a live factor that will influence your quality score and your minimum bids for your AdWords ads.
We first heard that page load time was coming to the Google quality score in early March. Google then provided advertisers with metric in their AdWords consoles so they could prepare for the day this factor came into play. Well, today is that day.
In terms of the number of people this has impacted so far, I have seen zero reports. Of course, this was just announced last night, so we still may see some complaints in the future – but none just yet.
