My review of the order of 200k GSA Ser backlinks. Receive the report with 230k backlinks in total (over deliver), & from 50k unique domains.
Out of 230k backlinks, however, 90% are redirect links, php exploit & indexer type.
I think this service is good to help to index your tier 1 backlinks, but not so much to power them up. Overall, I am satisfied with the service, but if seller can increase more proportion of other backlink types other than redirect, phpexploit & indexer, that will be very good to power up further our tier 1 backlinks.
Thank you.
