Attracting traffic is key ... without traffic, there is no reason for the program sponsor to engage with you.

Have you taken the Affiliate Bootcamp Training program as that may help you find ways to become more visible online?

You are in a high volume niche ... ask yourself

What makes my website/blog more appealing?
How am I differentiating myself from my competitors?
What value am I offering to my visitors to entice them to come back?
Am I presenting a professional and positive experience online?

Then brainstorm each of those ideas to see what or how you can make it better than it is, better than the competitors ... exceeding the norm!

Don't give up on the Affiliate Program rejections ... build content, ensure your sitemap is being accessed by Google and Bing search engines.

Check your keyword data to make sure you are using effective keywords ...
What words are others using that you think are more successful?

Focus on content and getting followers .. the revenue will come later once you have this in place.

Avoid posting a bunch of links .. people want value not unsolicited links, use them sparingly ...

I hope at least one of those tips helps ...

Best wishes
