I have never signed up to any blogging with integrity campaign. I am not even sure what it means. Are any advertising and sponsorship campaigns about integrity? Commercial media (broadcast and print) channels are only able to exist through advertising, sponsorship and subscription. (Apart from the BBC which is funded via the licence fee, which is essentially a telly tax.)
I have stated from the outset that I want the blog to be commercial and to make money. I have always been working towards this goal and intend to continue to do so.
I am happy to do sponsored posts and I sell advertising space. All sponsored posts are identified. Being commercial is not unethical or lacking integrity. It’s about working for money.
