I do this because I want to build a solid reputation and a loyal readership of people who trust me. I’d rather make less money and still have a reader than make lots of money and never see the reader again. For me, this comes not only from my ethics but my belief that in the long term building a good profile and reputation leads to other opportunities for profit.
Being in Australia, I’m not required to do anything by the law (although I hear talk that there may be changes around this). I don’t disclose every single Amazon link on my photography blog in a direct way but do I have a disclaimer/disclosure page on the blog. When I’m doing a ‘best seller list’ always include a disclaimer on those posts as the whole page is filled with affiliate links. I have also written numerous times on DPS about how the links to Amazon earn us money and help the site to keep growing and be free.
I insist my writers actually read the books, test the cameras and use the software products they are reviewing. I encourage them to be as genuine and unbiased as possible, to point out both the pros and cons of the product. While there’s some temptation to hype up a product and only talk about its positive points, a real review will help your reader relationship over the long haul and I find actually helps promote sales.
Be professional. When you submit a résumé, don’t type it in ALL CAPS and please don’t avoid the caps lock like the plague. Know how to use it without looking incompetent. Write in complete sentences with proper grammar. Of course, there will be exceptions, but even with the exceptions, you must keep it professional. You’re building their view of you.
