Facebook is conquering the world, but it's growing slower in its most established markets
   Facebook is conquering the world, but it's growing slower in its most established markets

Depending on what numbers you trust, how you're counting, the market and the period of time you're looking at, Facebook is already the most popular site on the web. On average though, in the US at least, it's still behind the big three, Google, Yahoo and Microsoft.

It's growing though, according to the latest comScore numbers, for July, Facebook added another million unique visitors to its site. 162 million Americans visited Facebook at least once last month, up from 160.2 million in June.

It's an impressive figure since Facebook is already used by a big percentage of US internet users.

That said, it still has some work ahead of it before it can claim the top spot in the US, which now belongs to Google. 182 million people in the US visited at least one Google site in the last month.

The figure includes YouTube visitors, which are quite a few on their own. That said, most YouTube users visit at least one other Google site also, the search engine for example, though the overlap is not 100 percent.

In between Google and Facebook sit, as always, Yahoo, with 177 million visitors, and Microsoft, with 174 million. In both cases, all properties belonging to the two companies were counted.

There's not much between the sites, Yahoo is less than five million unique visitors behind Google, but the ranking has stayed the same for years.

Even Facebook, which had a huge growth spurt for a few years, is finding it hard to grow past its current size in the US. While Facebook has well over 750 million users worldwide, it's probably at over 800 million already, unofficially, most of the new users come from outside of the US and outside of the markets it became popular in first.
