"Spam" avoiding the label is getting harder and harder.

No one wants to be labeled as a spammer.  The negative connotation is only one of the problems associated with it.  Eventually you will get kicked out of the places you are spamming and you can also have legal troubles from it.

Today generation of online shoppers, and web users don't care for it actually most hate it.  The way most people look at it is really simple, if you make money from your content, submissions, links, etc then you are a spammer.  Pretty Harsh.

The way to avoid a lot of this is through "Great" content.  Awesome content (not just ok) content doesn't get accused of spam, it get viral love.  Think about the ways you create your links - social bookmarks - link trading - social media - blogs.  What is black, what is white and what is grey that really shouldn't be passed on as white.  

Don't Spam

Create your links with a purpose - Content is king so make sure if your comment in a forum or a conversation then contribute.   Don't just create a link.  Don't just choose a popular video to add to your blog to get traffic, make it relevant.  Please don't highjack the content from someone else and just change the title, give the credit.

Just a few things to keep in mind as you work on your link building and content creation.  SEO through great link building can be effective and can be fun with a little creativity.
