I trade NUGT and sometimes USLV.
I trade FB.
A few others, but generally focus on 1-2 per day or per swing.
Many here confuse GDX with Gold.
GDX is an ETF made up of mining stocks.
Mining stocks do indeed participate in PM "trends", often "leading" rather than following.
IMO, trust that if the trend in PMs is going higher, GDX will pop higher.
If the trend is lower, GDX will drop.
It often is an exaggerated move on the trend.
Also, if PMs have settled into a range, the underlying stocks in GDX will often act jumbled and move on their own, following or leading the whims of analysts or quarterly window dressing of funds.
But you should NOT ever be surprised when they move in what looks like opposite directions.
They don't really.
Now 2 or 3x ecn or etf's are a whole other story.
There, you are also dealing with underlying assets such as options and derivatives that mimic the trends.
And they have a built in decay that over time MUST erode the PPS in relation to underlying asset classes. Thus, they are only for day or swing trading
Just my op.
PS: I am long many miners and physical Gold and Silver.
I trade NUGT and GDX
That said, Google is far and away the leader in DEM,or search engine marketing.
They are tweaking and improving Behavioral targeted marketing,as is Bing/Yahoo.
BUT, in the coming months and years,FB should be able to monetize this aspect of the business by providing the most accurate behavioral marketing data.
We'll see. But I wouldn't bet against them.
CPM is cost per 1000.
That's the number of impressions or in other words, number of visitors.
You then figure out your cost per click based on what you are paying by dividing the clicks into your cost.
Which is meaningless unless they buy.
Then you measure your conversions, rate and cost.
The generic name for this method is PPC or pay per click.
BUT,CPM is cost per 1000.
Nope. CPM= cost per 1000 based on visitors to the page, unique visitors.
Page views or unique visitors.
They cannot charge you for the number of clicks because they don't know how many times your ad will be clicked right?
IF a vendor was charging on the number of clicks,that would be more performance based, after the fact.
They don't typically do that.
The CPM will increase based on a number of metrics.
1-They will charge what the market allows. Meaning, they will get what they can. As advertisers buy into this medium, the CPM could go higher, but not necessarily across the board.
If I were pricing, I would select industries and charge different CPM by industry.
The more competitive the industry, the more I would charge for unique page visits.
2-I would design rankings for FB users. Higher "power rankings", charge the advertiser more.
Meaning, some users have more followers than others. And some users will eventually be measured by how much THEY buy and influence others.
I don't want to give away all my "knowledge" but they have a ways to go.
When they eventually get their behavioral metrics working,it will be a gold mine.
