The topic you choose must have enough depth that you can create a lot of content for it. This is important for building an authoritative site, for search engine optimization, and most importantly, for the end user. If you don't have enough content about a topic, you're not going to be taken very seriously as an authority on the topic and it's unlikely you can convince someone to make a purchase from you. 

Hey Denise, you can always sign up with the same domain name if you’d like. As long as you have the affiliate link, you add it anywhere with one account. However, it’s a good idea to let the affiliate manager know every domain that you own, as getting approved regularly requires that they know the websites that will be sending them traffic. I hope that helps!
I started a blog which I plan to monetize only through affiliate marketing and my own products, no ads.

The Sandals affiliate program pays you a commission for referring users to book either a stay in one of the Sandals Resorts, or booking an activity. While 4% might seem like a small percentage, these luxury resorts have daily rates that range from $150 to over $2,000 per person -- which means, if a couple were to book a romantic week in a Sandals Resort at $500 per person per night, you would earn a commission of $280!
The products and services you will be promoting to your audience must be relevant and good quality. Make sure you believe in them and know everything about them, because this will be crucial to you delivering the sales pitch to your audience. You need to build trust with your audience so make sure the products and services you choose to promote are trustworthy enough. 
Although it has a dynamic and well-designed website, PeerFly has a limited range of offers at any given time (around 8,000). On the upside, it does offer good commission/payout rates, lots of FAQs and educational information, and regular contests and reward programs that can substantially increase your bottom line. Based on online customer reviews, Peerfly enjoys a very high reputation amongst participating affiliates.
Thank you very much. I signed up to a few here and I am very grateful to you for making all of this valuable information available – you have saved me time. I could not sign up to Shopify as it just kept on reloading page to SIGN IN and not create a new account – confusing. VigLink does not allow a new account sign up either.. Rakuten did not say if they charge to be apart of their affiliate prog and actually there is no sign up for that option. If you can help me with these three prog’s… Read more »
