Just have to say scrapebox is awesome! Support is really awesome too and there's updates almost everyday. There's a million uses for it if you're creative and it has literally cut down days of work into just minutes!
Although those of you who are just copying the comment examples in this thread really suck and are going to ruin it for the rest of us if this gets out of hand. Like the moron who keeps spamming me with comments like this:
Geez - OK people HERE is what you do to get a good comment list:
Follow this if you do not know how to write your own - this is for your benefit as well, spamming shit comments will ruin it for all of us eventually and then scrape box and all other tools like it are useless...
Go search for your terms, scrape the sites, filter dupes.
Then grab the PR of the list, sort by highest first.
Go to the top 10 blogs on the list, copy those URL.
Open them in Google, go find already approved comments. Copy a crapload of them over to wordpad.
Edit them a bit to make them your own, DO NOT USE THEM AS IS. Add a sentence at the end and change words around, or if you want them really long term, do that with spinner text.
If you do that with 50-60 comments, you will have an awesome generic comment file that works great, and since the comments were approved on other blogs, odds are they will be again.
Save the comment list for each keyword you are targeting. I use something like generic comments - how to buy gold, generic comments - how to get traffic etc. I have a bunch of them I build and save and can use over an over again when I have a new site with similar keywords or need to do another blast for an existing site.
Just make sure you choose comments that are general, do not pick any with specific names or events, those are really custom for the post they were on and they will not get approved.
Additionally, use common sense and do not copy the date, user name or signature either. I should not have to say that, but you never know how people will interpret what you write ...
Hope this helps
