Hi @Syamraj K
, It is now called CJ Affiliate.If your a beginner, you can simply sign-up for free here.
. Once you are signed up, complete your profile to ensure you get fast approval for any affiliate program via CJ. Now, click on get links and you can either search for your target affiliate program via Advertiser list.
One thing which I like about Commission Junction is you can easily select product based on different niche. Especially if you are one of those who are running different niche blog, you can pick niche based product which you can put into your blog and make huge commission.
I hope this helps.
