How to calculate the costs of contextual advertising of the program during the specified period?

Question

contextual advertising

How to at least approximately find out how much money will be needed to advertise a product within N months? It is desirable to support the answer with references.
I couldn’t find it anywhere, everywhere there is chatter “around the bush”, advice on reducing costs and choosing strategies, but there is no answer to such a question.

Answer 1

Google Keyword Planner.
In general, I use media planning templates designed specifically for such purposes.
I usually recommend taking the "Test Budget", spinning it up, getting 100-200 clicks and scaling it up to larger amounts.
If you like, I can run your requests through a media plan template and come up with the result that a professional agency would give you.
How to get statistics later will come in handy =)
If all campaigns advertise 1 product:
Go to the AdWords interface, then click "Quick statistics" at the top in the row of tabs. You can see it
on the screenshot .
If you have many campaigns for different products, then on the "Campaigns" tab, check those campaigns that advertise the product whose advertising costs you want to calculate, and click "Labels" (screenshot) . Give all of these campaigns one label. Then on the "Quick Statistics" tab, click "View->Labels->Campaign" (screenshot) , then select the desired date range at the top right.
Voila, it's simple!
Good luck to you!

We go to Yandex direct, drive in the words, look at the price and clicks, multiply and get the budget.
