Well you can go for quality OR quantity in my experience. Or both We'll handle your scrapebox mass commenting and article submissions for you. What is your budget daily?
30 links that to with quality, high pr sites, same niche will be a good tough task. It is also not impossible. All d Best.
I paid someone some $ for an xrumer blast but it was really a waste b/c none of the pages where my links were placed are pinged and they are all horrible sites. Like everyone said, take the time to contact people and get good, high quality links.
There are lots of ways...but why only 30? Anyway, the best links you can have come from good article marketing.
Quality Links are more important than quantity. Few Links from High Page Rank sites having more worth than more links from the blogs or websites with no page rank. Thirty Back links in one day is not difficult. Join the High page rank forums and post. You can easily get thirty back links per day.
I can recommand thelinkjuicer.com - in addition to my own service, of course. ;-) (But I am doing more than 30 links a day.)
I argue the same with a lot of people had said earlier, I agree the manual way, do not use the software, because as I know, google does not like it. Let's just looking for a safe way
you will always get dissenting opinions on a topic like this, but generally, you want to stay away from spammy software. That should help you out a great deal.
I am also building backlinks and i do blog comments, forum post. Just two thing but it is really take me long time because i have to read all the article of blogger to give them the nice and useful comments.
