Long-Tail Keywords – specific keywords usually with 3-7 individual words in a phrase. They are highly targeted and MUCH easier to rank for than broad keywords (all mine are long-tail). The lower your domain authority (check using OSE), the less competitive (more long-tail) your keywords should be. If you can get more specific and the keyword still shows up in Google Autocomplete, Moz Keyword Explorer and other keyword tools… choose the SPECIFIC one.
Hi Rob, ebay has an affiliate program, it’s called ebaypartnernetwork and I use it a lot on my two sites. It is making me constant sales, even though it does not amount to all that much, around $50/month. But again it depends on the items you are selling. Mine are in general not that expensive, so I earn less. I find ebaypartnernetwork works better for me than Amazon.
The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
If you have built up an email list, you could also promote your affiliate offers via email promotions. Just make sure you build up a relationship with your audience first instead of going for the hard sell straightaway. The emails you send out must contain your affiliate links to products so when your audience click through. the sale is attributed to you.
