I have received last week a warning from Google Webmaster Tools about the fact that my website is not mobile-friendly.
And it is not.
The reason why we didn't opt for a responsive design is that last year we signed a two-year contract to display three advertising banners (the largest being 728x90). Without these we would have no revenue to cover hosting costs.
Now it seems Google is forcing websites to go responsive else they would be penalised in the search results.
I was wondering if there is a solution to go responsive yet continue showing the banners in a clean way.
