Welcome to the Q&A Forum

Thanks Kerry.  That was my plan. To slowly build directory listings, then work up to anchor links.

Thanks Joel.  That makes sense to age the sites based on my experience with other sites.

I am building a couple of brand new websites for myself and a client. I'm operating on a fairly limited budget ~$1000.00 for 3 sites.  All 3 are in the life sciences and chemistry field.

If you were me what are the first sites you try to get links from?

Or should I just hire a link building service like Paul and Angela's?

I guess Im looking for specific domains that are a must to get links from.
