What was the revenue growth rate for Meta in Q4 2020 compared to Q3 2020 
s just the shift to online commerce, as well as the ongoing -- the shift to more spend on products versus services. In Q4, we also saw strength with sort of our full range of advertisers. We have seen sort of small- and medium-sized businesses come back and start getting strength in Q2 and Q3 or Q3, specifically.
And then Q4, we also saw strength from some of our largest advertisers as well. So as you look out in 2021, I think we're just going to be facing tougher comps in the back half of the year. Some of those things related to the pandemic had the potential to revert, whether it's more consumer expenditure shifting toward services away from products. So that will make it a little bit of a tougher comp.
And then you layer on top of that headwind to growth related to privacy-related headwinds. The biggest factor there is iOS 14. So we certainly anticipate growth, but we're just looking at tougher comps as we hit the back half of the year given really, most importantly, the strength that we saw this year and then, on top of that, the headwinds that we're seeing from some of the privacy changes.

Your next question comes from the line of Justin Post from Bank of America.
Justin Post -- Bank of America Merrill Lynch -- Analyst
Great. Thank you. I guess I'll ask about regulation. I know it's a tough topic.
First, Mark, in your prepared remarks, you elevated a little bit competition with Apple. Is there anything going on with iOS 14 besides IDFA that maybe puts you in more direct competition with Apple? And then secondly, obviously, the FTC filed their case since the last earnings call. Maybe just open forum, any thoughts on that that you're able to share. Thank you.
Mark Zuckerberg -- Chief Executive Officer
Well, in terms of the competition with Apple specifically, I laid out three or four product focus areas. And with the exception of the work that we're doing on communities, which I think is quite separate from the work that they do, the other three areas, I think, are going to have very significant competitive overlap with Apple. In messaging, certainly, iMessage is the most popular service in the U.S., I think, because of the fact that they pre-install it and give their app several advantages that other apps don't have. In commerce and supporting small businesses, I think there, you have some of the iOS 14 changes that we think are going to be very problematic especially for small businesses.
And then longer term, as we move toward building the next computing platform, I think we would expect to see them as more of a competitor there as well. So I do think that this is sort of shaping up that -- we face many competitors, right? There are a lot of competitors in the core social app work that we do. [Technical difficulty]

Was there another question on that last one that I was supposed to answer?
Dave Wehner -- Chief Financial Officer
Well, there was a question about the FTC.
Justin Post -- Bank of America Merrill Lynch -- Analyst
Hey, guys, we're back.
Dave Wehner -- Chief Financial Officer
All right. Are we on now through this line?
Operator
Yes, you are connected.
Dave Wehner -- Chief Financial Officer
OK.
Mark Zuckerberg -- Chief Executive Officer
All right. So where did I lose you?
Dave Wehner -- Chief Financial Officer
I think you had covered the question of the dynamics related to the competitive landscape, and then there was a follow-on question around the FTC case and any thoughts that we have on that. I don't think we have anything we necessarily are commenting on at this point.
Mark Zuckerberg -- Chief Executive Officer
Yes, nothing on the case. I mean, on regulation overall, because I think some of the question was focused on that, the point that I would highlight is I actually think it would be very helpful to us an
