How many keywords should I use in order to keep fast links building?

Manola

I've added to my project 20k keyphrases related to my nieche and run it for approx 2 hrs. Got the following statistics:
Submitted: 2200
Verified: 125
LPM: 5

What parameters should I look to in order to increase link building speed?
Will using more proxies help? (Currently using 10 semi dedicated proxies)
Is is make sence to encrease amount of keywords or shoul I use alternately different portions of keywords?

Thanks in advance!

Sven

The pingback is one of your problems. You should not use that engine as it requires modification to your site to work (read notes when mouse is over it).

Also Comment engines producing a lot submits but little verification if you don't use auto approve lists.

Some article engines like drupal, wordpress produce a lot submits where you later can even verify and login, but SER can then not see a place to place a link and that resources are wasted then.
