Sorry, yes. So I mean the trends we saw really in the course of the year, our biggest -- just as a reminder, our biggest step down to us that we saw were in Q2, and we saw a much more normal seasonality into the second half. And as David said, December was softer, as we, I think, heard from a lot of our peers as well with relative strength in January and into February. For March, we've got positive indications from the market. And so cautiously, we're expecting a normal, I would call normal CECL uptick in March. So visibility, obviously, remains limited. But again, our diversity of our advertiser mix and without any reliance on any specific vertical is certainly an asset for us. Just from a verticals perspective, I think you may have asked in Q4, we saw positive signs. Again, we don't overly rely on any one of these, but positive signs from automotive, travel and retail while finance and entertainment were actually weaker in Q4 than Q3, which is unusual. And political is minimal. We didn't expect much so not very disappointed by that, but that was it. And then for 2023, I think you started to say this, but we're really in our normal process for forecasting that we've been using for several years, which is expecting -- using the trends that we see into Q1, flat, macro, normal seasonality. And then -- and to get that growth, it's really coming from yes, lapping and the things we've done really in the last couple of quarters that will start to pay off, I think, really more into the second half of this year just to expand briefly on those. Like I said, we've added a ton of supply and premium supply at that. And we're traditionally a land-and-expand model is how we view ourselves. That's why we report the net revenue retention and why it's been over 100% historically this notwithstanding. But we drive that growth on this -- on our existing and our recently won partners through technology, learning the audience, driving out the adjacent, expansion, getting -- really finding out how to best monetize for each partner, which is largely through our technology discovering that over -- and it takes a couple of quarters from our history and what we tend to do. So I think we'll also grow in our model through, again, adding new partners, and that's both traditional publishers and what we call the platforms or the non-publisher partners, that's the original equipment manufacturers, browsers, minus one screens. That's more than 10% of our revenue at this point. And I don't expect another year of 16% new growth, but certainly the 7 that we came to kind of see every single time is probably more in the ballpark of what to expect there, though we're not guiding specifically to that. And yes, as you know, we continue to invest in our algorithms and optimization. Yaron mentioned on the call. We actually saw a really, really big gains in our predictions. We just -- with the supply and demand imbalance, we haven't been able to see it come through our overall results yet, but more coming there and we're, obviously, cautious about how we put it in just based on what we've seen this year. And then we just say expansion of video and our full funnel offerings of the article placements, different types of other formats and placements, and we'll probably talk more about that in the coming quarters as an area of focus. And then at the same time, keeping expenses flat, which is what we assume in our guidance for the year, and we plan to -- we've been flat with the kind of look back at the last 1.5 years, by the way, by operating our core more efficiently and really, really focusing on prioritization of how we can invest smartly and repurpose resources to expand our core. So that's really the story for the year. As far as I think your second question was just about the margin. The things that I mentioned have brought the margin down are actually the same types of things that will bring it up. So just what those are, again, mix. So it's always going to be a factor. We've got thousands and thousands of partners and they all have different kind of take rates, and it depends where kind of the mix of the revenues generated. Just to give an example, not talking to any specific publishers, but we're not obsessed with the number, when we're adding a new partner if it's at a lower than average rate, but we still see the dollars are attracted and profitable. There's more to it as well. I mean, the reach and the audience that it brings us for our advertisers that might convert well for certain text advertisers an open share of wallet is also what we look at as well as the data that it has. I think Yaron already mentioned just how much -- how many more data points we're adding now with adding all these partners. And we view that as growing the yields across our entire network when we improve our data as well. The other -- that's mix. Demand headwinds really and the supply/demand imbalance is probably the biggest thing, if I had to pick one that's driven it down and macro improvement will certainly be the biggest thing that drives it back up. But I think there's some things that we can certainly do ourselves to drive it back up through just, again, better yields, better click-through rates, et cetera, to find some leverage there as well. And then ramping up again on these new partners, we find that it takes several quarters to drive the yields higher and a lot of these deals, that means higher take rates as well. So the things that are down or are the things that [Indiscernible].
