What consitutes a good paid post?

It's all very well seeing paid posts as a means to generating income, but how can we generate income through paid posting, and do a worthwhile job of it too?
Today I am going to share some rules, and some hints (after all I have been doing this for three years now, I should either be getting good at it, or thinking about jacking it in!).

1. Rule number one is to read the requirements carefully, if it says three links, use three links. If you should be using anchor links, then make sure the anchors and the links are exactly as stated.
2. Rule number two is to write well, use good grammar and make sure you use a spell-check, you can get away with lousy posts in some cases because they are only looking for a link, but you will stand a better chance of being offered 'work' if you can demonstrate that you do a good job.
3. In a lot of cases, you don't need to even promote the product or service, they are only looking for an anchor link, you are free to express yourself so keep it real... There are some occasions when you will struggle to come up with an angle, but give it some thought and eventually you will probably come up with something that works and hopefully doesn't look out of place on your blog.
4. Use pictures where you can as long as the advertiser does not mind, in most cases, they will encourage you to use graphics and logos from their own website, as long as you are using your own words.

If you feel a bit of a cheat writing posts like this, then I came to terms with it this way: A paid blogger is like an actor doing a commercial voice-over, you are just giving life to someone else's sentiments, and you should do it in the best way that you can.
