Hi STEEMIANS,
Welcome to the part 3 (the conclusion) of " Common Mistakes Steem Users Should avoid.
This mistake is commonly practised by authors while our last post covered the mistake acted by followers in form of comments.
**AFFILIATE or LINK SHARING"
Most of the people on steem think that this is great place for affiliate marketing because most of the users here are to earn some money so they start promoting offers with there affiliate link attached to their posts.
This isn't a great idea at all, because you will be flagged by steemcleaners as attaching any affiliate link to your post is considered spamming.
This will have a negative impact on your reputation additionally you will not be able to earn anything from your link as the post will be hidden once it's flagged.
I never have promoted even my own website. I remember once my post got flagged when i shared affiliate link in one of my review post. This was true disappointment for me, will you belief yourself when you make a good post by putting some effort and you are flagged for small mistake. So this type of thing should strictly be avoided.
This post is final one of this series.
