How is it? Is it really effective in getting backlinks crawled/indexed? I owned 3 copies of GSA SER and I thought of getting the SEO Indexer. From what I've read in their salespage, SEO Indexer sends the links to WHOIS and Statistic sites, then it pings the links. My question is, does it really help? From what I understand, if you try to submit a website to WHOIS or Statistic sites, it will only allow parent URLs (example: blackhatworld.com) and it will not accept any deep-linking urls (http://www.blackhatworld.com/blackhat-seo/blabla/test-test). So I guess that just leaves the software to ping all the links to ping sites? I know for Lindexed.com, it publishes your links in a webpage and pings them, making Google Bot to crawl them. So how effective is GSA Indexer compared to Lindexed service?
