I went through the same phase with Clickbank. I started years ago uploading videos. I did like 60 completely unique videos at the time and didn't get 1 sale.
Then summer came around, I randomly get a $125 check in the mail. 2 weeks later a $210 check.
So then I decided to work harder and smarter. Spent weeks doing nothing but keyword research. Improved all my copy. Started working CB again. Peeping competitors. And it took another 3 months to get another product converting.
After that though the laws of math and probability turned in my favor. When I first started I had to upload 60 videos to get 1 product converting. Later in the game I was getting 1 product converting for every 5 new products I targeted. Then kept going and going till I broke my first $200 / day.
The thing I learned about Clickbank you need to PAY just to learn how to get schooled. In the form of hard work & frustration.
It's extremely frustrating when you invest xxx amount of hours doing something and make little money. But when you've ALREADY INVESTED time and made sales, the WORST thing you can do is stop trying. There's this point where your method becomes so refined and predictable that profits explode, it's the most rewarding feeling in the world.
For me when I started I was making very basic mistakes...
1) Spending a few hours looking for keywords and thinking that was "ok" or sufficient enough.
2) Using Googles keyword tool to find alternates.
3) Using other keyword software to find alternates.
4) Promoting mediocre copy.
5) Not taking time to review products I didn't know shit about. I'd literally go to wiki (rather than getting review copies) which is useful but not enough.
6) Not really thinking things through like an engineer.
7) Not optimizing "weak" keywords for conversions.
The weird thing about "mistakes" is there's obvious mistakes, then mistakes you'll never know you're making till profits tell you. Here are some mistakes I stopped making that helped a lot....
1) Realizing it was not just ok, but almost mandatory to spent days sometimes weeks doing nothing but keyword research. There is never no such thing as "too much keyword research". There's just a saturation point you hit where you realize you have more mining locations than you'll ever have time to mine. Till this day my main master list is the most valuable thing I own. Reason being, it wasn't bot generated. It's over 16,000 keywords. Every keyword on that list I manually researched to 1 degree or another. Then I printed the list out and spent months coloring certain keywords so the list is prioritized. Everytime I look at it it's like I have a small army of keyword intelligence officers out in the field feeding my secret information. What I like most, as much time as I put into my list I'll never have to do real keyword research again. Do the grunt work. A strong master list is an invaluable asset.
2) Same for market research. If you see a book on Clickbank look for similar books on ebay or amazon and see if they're selling.
3) READ REVIEWS from people buying these similar products. Those reviews are buyers TELLING YOU how to sell to them. And you'll learn awesome tips. When you see 10 people complaining that the book should have spoke more about something or less about another, you integrate this in your product selection, address it in your copy ... it compels people to buy cause they truly believe you "get it".
4) Using your brain, a thesaurus and authority sites to find weird "human" keyword combinations that bots will not find or tell you about. Often times words or phrases have twin brothers or cousins that a thesuraus may not find. But just by looking at a thesaurus you remember them. Or you find them researching. Like "music software" can be called "music sequencer" or "beat maker" or "step sequencer" or "audio workstation" etc. Many times people search unbuyable generic phrases to buy something specific they're not even sure what it's called.
5) IGNORING keyword search volume data. The SM gives you maybe 1/4 a glimpse of the overall picture. I can't explain how many times my sales & conversions completely CONTRADICTED this data. Like I'd target a 3,000 SM keyword over a 720 SM keyword cause they were both similar except for the searches. Then the 3000 SM keyword converted at 2% and the 720 converted at 18%. So the end result I made 5xs more sales from the keyword I didn't wanna target cause it seemed "crappier" or "too easy" but turned out to be a mini goldmine.
6) Learning to promote "wildcards". After I started getting confident, I started playing tricks with my brain. If I saw a keyword I was highly critical of, maybe the niche was weird, maybe I didn't think it had lots of buyer intent, maybe I had another more obvious keyword I thought was better..... >>>I intentionally started targeting wildcards. Low hanging fruit thats confusing or not very appealing to most marketers. I did this cause I realized, "if common sense has me feeling this way, chances are many other marketers feel this way". On example of this was "how to stop masturbating". I felt bad about that keyword. Didn't like it. I had another marketer show me how he targeted it and didn't get any sales. That it was a shitty niche which confirmed my suspicious. But I resisted my common sense bias. Went hard at that keyword and it performed extremely well. Then the next set of keywords I did the same thing going after a wildcard keyword with no-so-great metrics. One of those keywords I'd immediately throw away. I ranked in 2 weeks like cake and conversions almost hit 30% at 1 point. Till this day that keyword performs great. I've had 0 competition. I think 99% of marketers think the keyword is crazy or shit when truth is it's gold.
7) Going the extra mile for conversions on keywords that don't seem to deserve it. People really don't seem to realize how much money you can milk from a sub 1000 SM phrase. I have a 810 SM phrase where initially I wrote a shitty PDF and ranked it. I was getting low conversions... like $25 / week from that 1 phrase. Then I rewrote a much better PDF. Put a full day into it. Reranked cause it was easy and suddenly that 1 PDFs pulling $250 / month. I thought, "you have to be kidding"? $150 more a month from 1 day of real work?
Most of the most important things I learned were in that short period, 3-6 months after my earnings slowly began to take off. That's why I HATE seeing marketers give up AFTER THEY'VE ALREADY GOT THEIR FIRST FEW SALES. Their perspective is "it took this much time to make this money!? fuck this". Instead they should realize, "I may be 3-6 months from striking gold". If you keep working and refining your method, it's only a matter of time before the laws of probability and profits >>>MUST TURN in your favor. You don't "think" they'll turn. You KNOW it'll turn. When you know it you'll fight that much harder and it'll happen much sooner.
