i am looking for a provider of verified GSA SER lists. You should scrape your own lists and/or be using a few different providers. I am interested mainly in contextual targets - Article directories, Social network, Wikis, custom coded sites of yours (if any), but i can also use some of the other platforms.
For the list that you will provide you have to keep track of the blacklisted, non-indexable domains (and of course remove them) and constantly improve/update/expand your list.
The lists should be compatible with GSA Captcha Breaker and CB should be the only service since i am interested in high volume of links.
The price will be negotiated based on the number of platforms/unique domains you can provide, quality of the list, drop rate, etc. We are talking about monthly payments here and live sync with dropbox for example.
If you are interested, send me screenshots of your current LPM, number of contextual links you can build per day with your list and anything else you find related.
