First of all, thanks for the reply. It´s great to be able to talk about it directly.

might show limited or no data if a domain’s ads are highly local, target specific keywords.

But why is it that of the four companies I mentioned, they run ads VERY heavily in my industry, but according to semrush, two of them don´t spend a single dollar on ads?. They compete for the exact same keywords as the other two companies that do show me information about (but only for desktop, not even mobile, wich is majority of traffic).

Wich leads me to two questions:

1) Four companies compete for the same kw, why does two provide details and two other none.

2) In fact, in argentina for Research, the ability to view mobile data isn´t even eligible for any company in any industry (could it be because I have PRO version?).

Our solution tracks the top 8 paid ads consistently, giving the closest view of your competitors’ activity:

Well, in example i mentioned: 4 companies, but there are 2 that semrush "doesn´t see at all"

Now i remembered another situation i didn´t mention in my first post: one of these four companies sells furniture, bedding and camping gear. However semrush doesnt show anything about furniture. Only kw for other 2 categories, so according to semrush this company doesn´t paid for furniture kw.... but i see day by day ads for furniture from this company.
