case study: how to cheat the crisis?

Good afternoon, dear users. I read previous posts about online advertising during the crisis. I would like to share some of the experience from the point of view of the company on which the advertising is placed

So how do advertisers now behave?
We have several well-visited portals on various topics. It is interesting to observe trends in each of the industries. Banner advertising on sites dedicated to real estate (restate.ru), has become less popular. It is logical - "real estate" is now going through hard times. Also began to buy less banner on the automotive site (110km.ru).

But at the same 110km dealers adjusted their shares - sponsorship of headings for brands became better sold. The real estate website sells sponsorships of thematic headings.
Contextual advertising is also well-kept.
In a crisis, there was a serious increase in demand on the job search site (vakant.ru).
We monetize the vakant, including using SMS messages to raise the summary in the results of issuance. So far, of course, it does not give a big profit, but the volume is gradually increasing.
At the moment, we still manage to hold on and not lose our positions - but this is helped by the orientation of the portals to different industries. What will happen in the future is hard to say.

IMHO, now local advertising tools with good targeting will become more and more popular (for example, advertising on thematic car headings devoted to a particular brand or well targeted advertising on social networks). But mediyka, perhaps, will give up a little position.

I will be glad to know about your observations about changes in Internet advertising, as well as possible forecasts for the future.
