To be safer and to avoid confusion better do it manually.

manually is best

To start out, manual is better but once you get moving and you launch more sites, you can not keep up with manual submission.

I'm tempted to do it w/ software - but I have client's websites that I'm responsible for - so to be on the safe side, I do it manually. However, I usually find relative sites to backlink from...

Manually you get higher quality and better backlinks usually. I would recommend doing it manually. Now if you want to integrate profile links, then go ahead and outsource that or use software. Manual is better in my opinion. I have a few clients and don't really use much software at all.

Manually is the way to go, you want to look as natural as you can to the search engines, this way you can build more trust and authority with the search engines.

it all depends on several factors, but always focus on the following:

1) what is your current domains benchmark.

2) what is your current link graph and how does the next step your planning on taking meld with that existing graph, will it bring about any red flags, etc?

3) what are you trying to accomplish (Keyword Ranking, Overall Domain Authority, Boosting PR, etc.

4) What kind of time are you able to invest.

5) Can you afford to outsource it or do you even want to.

6) Do you fully understand how to use the tool / script / service or software? Do you fully understand what the potential pro's and con's of each are?

7) Do you have previous experience actually doing what your planning on doing?

8) What your plan B and plan C if things go wrong.


Best of luck and let your common sense prevail...

I suggest you make it manually.

Semi-Automatic with automatic form fillers such as RoboForm is a good way to do it fast and at the same time make sure the profiles get created the way they should
