How does advertising work towards large companies?

Question

Marketing

I never understood how advertising directed towards large corporations works. Are there people here who understand this?

If the company is b2b, then it advertises in the direction of SMEs
. If the company is b2c, then it focuses on individuals. Through target, context, SEO, banners, videos.
What if a company wants to sell its products to large corporations, banks, factories? How then to build a marketing strategy? Through what methods to influence a large potential client? What channels are there?

Answer 1

It depends on who your client is, if it’s a trifle like a bank’s point, then they bombed all Internet channels, plus PR is active there, well, they branded all their points of presence offline.
If there are any factories, of which there are ten, then just two direct sales managers behind the eyes, without any channels

Answer 2

In this case, if we take some mass events, then these are forums and conferences where your target audience is. The agency I work for finds major clients at themed events, where I act as a speaker with an interesting solution to the problems of this business, and then the decision makers find the company themselves.
