2 million advertisers on Facebook up 33%. 4 million active on Google. The advertiser switch to digital is on.

Another Facebook milestone this week as announced by Business Insider, achieving 2 million active advertisers, a +33% increase on July last year.

Facebook is therefore gaining ground on Google but leaving Twitter in its wake at 60,000 advertisers. Google has 4 million.

These advertiser relationship growths, point to a healthy future and the opportunity to grow the revenue (spend) per advertiser in the longer term. If you have that many clients, you're going to grow.

If Facebook keep developing their Search capabilities, they could really extend into Google territory and we know that Facebook continues to grow its users year-on-year.

But importantly too, is shows the advertiser move away from traditional. If digital wasn't of real, core interest, they wouldn't be building these relationships. It's coming, it just has taken longer than we thought.
