Hey Marie, good plan on starting guest blogging! Good luck. Here's my way to handle this:

1. No more than 2 links in the byline. More looks somewhat greedy and doesn't make sense anyway.

2. I wouldn't guest blog on a PR N/A site but in all other cases PR doesn't matter. There are very new but very active sites: lots of tweets, likes and comments, lots of activity. Even if they are PR0 or PR1 they might be worth a show for two reasons: (1) They are likely to attract traffic (2) They are likely to have accumulated some considerable link power but it's not that visible yet using the tools. If there's activity on the blog, it's most likely to grow very fast! Besides, these new blogs are usually much easier to communicate with!

3. None that I have faced, but here's one recent comment from one of our users: it looks like his guest post has outranked content on his own domain, so I'd pay attention to what you are guest blogging it to avoid your own guest posts competing with your own pages in Google search.

Let me try to be very clear. Please email if you have more questions (I got both of your emails, so feel free to use the email)

When guest blogging, are you promoting ONE site in your byline in each of the guest posts? There can be different pages from one site, but one and the same domain.

For example:

• Project name: SEOmoz
• Base domain: seomoz.org

Then when you decide to upload this page, for example: http://www.geekwire.com/2012/seomoz-secret-startup-success-rand-fishkins-tips/ - the tracker will automatically identify the backlink to track - http://www.seomoz.org/dp/seattle-startup-marketing - because it has seomoz.org base domain.

By providing the base domain, you make your own job easier because you don't have to manually provide the tool with the backlink to track!

Hey! Sorry I am a bit too late on this one, but hopefully I can help!

I think I have been fair, 500 words of unqiue content with 1 anchor text link in the body, thats it.

Quite fair, but not exactly enough. The thing is, that's guest blogging and for bloggers to really want your content, you need to make it blog-friendly ("viral", in a way).

MyBlogGuest is no different from the whole Internet in this respect. Some topics always do well and get attention.

Usually these topics get picked in no time here:

• Facebook
• Twitter
• Apple
• Google

So if you want to get quick offers, consider changing the focus towards the above topics. You can easily do that almost with any niche. For example, if you are into "loans":

• Free iPhone Apps to Quickly Calculate Your Loans

• HOW TO: Use Google Shortcuts to Estimate Your Loan

• etc

If you add some screenshots, CC-attributed images, etc, your articles will be picked in no time!

I hope that helps!

While I do agree with what Casey says, I do cross-link my guest posts around the web in a most natural way. My guest articles are all in the same niche, so they are somehow cross-related, so what I do is to mention my guest articles now and then. That effort has been noticed by the way:

Guest blogging on Bloggingpro she links to another post she wrote on cleverdude.com. I’m sure she’ll get invited back.

Not that I'd turn that into strategy but why not if those links make perfect sense and build better relations with bloggers I guest post for?
