I haven't done any GSA spam for ages so I decided to do a little experiment. tier1: 800 verified urls (articles, social networks) tier2: 50 000 verified urls (profiles, bookmarks, guestbooks, directories etc.) I let it sit for one week. I used two different indexing services for tier1 and one for tier2. Indexation rate after a week: 6.8% (54 out of 793) As you can see, indexing services are just wasted money nowadays. And please don't say 'they don't get indexed beause your content is crap'. I can assure you my content was excellent. Tier1 article was hand-spun on paragraph, sentece and word level. It reads out very well. Also all of my tier1 target sites are indexed in google. My question for all of you GSA wizards over here: How do you get your indexation on a decent level in 2015? Google has obviously cracked the indexation business lately. UPDATE: I decided to continue my experiment. I ordered a 600 000 blog comments blast from fiverr targeting my tier2. Let's see if that helps.
