Backlink Indexing Service Comparison Case Study -

I am not the original author of this thread but he gave me permission to post it here after I PMed him.

...the results of one of my extensive tests I started in April 2011 regarding backlink indexing services. I have used BE, BB, BIE, LV, and obviously the services I'm comparing in this thread. Services like BE and BIE are good but can take weeks/months to get warmed up for decent indexing rates not to mention the time it takes to setup and manage when accounts get banned, etc.

The purpose of this particular comparison is to test the automated solution indexing services where you don’t have to do anything yourself, other than submit your backlinks. I always try to figure out the most cost effective way to spend my money so I thought this test was in order; not to mention that many people are paying for services which they are not really sure are worth the money. I'm not claiming this is the definitive test to go by. I am just sharing the data I recorded during my testing. My next case study may report on the improvement in SERPs from getting backlinks indexed (although this is a little trickier). My initial guesstimation just based on what I have seen occur on my own sites is that getting your backlinks indexed can really mean a huge boost for your rankings. That being said, on with the test…

Link Setup:
D-Day Minus 5
Post Thousands of Forum Profiles using Xrumer with the same 3 signature links per profile
Wait 5 Days to account for any banning and/or automatic Indexing.


D-Day
1. Run all links through ScrapeBox Link Checker – Save Results
2. Run Saved Results through ScrapeBox URL index checker (Run Several times with Private Proxies to ensure high degree of Accuracy) – Save Unindexed Profile Results
4. Divide Forum Profile Links into groups for each Indexing Service
a. Each Group receives 500 unindexed, alive forum profile URLs
b. One Group of 500 is set aside and not used for any services. This is a control group to see how many are indexed without any external boosting.
5. Insert Links into each service and monitor results each day at the same time every 24 hours for the next 30 days using ScrapeBox to check for Indexed Links (See Chart for Day by Day Data)

At the end of 15 Days the Control Group of 500 URLs which received no external backlinks was found to have 27 URLs Indexed Naturally and 116 dead or banned URLs. Therefore, a Natural Index Factor (NIF) of -27 will be applied to each Indexing Service’s final Indexing Rate Total when calculating Final Indexing Rate %. A Base Factor of -116 will be applied to each group’s 500 URLS bringing our new Base Total to the modified 384.
Bottom Line: We are not going to count URLs that would have (on average) been indexed automatically by Google, nor will we penalize these services for URLs which were banned (on average) by the forum admins.

These are some of the toughest links to get indexed. Everyone knows that getting articles and blog type sites indexed can be challenging, but not impossible. It is the massive amount of forum profiles which can be really powerful if you get them indexed, but accomplishing that has become increasingly difficult.

The Bottom Line after 15 Days
It seems pretty evident that BacklinksIndexer.com has its act together and knows how to get some links indexed. As you can see from the graph they are well ahead of the pack. I only wish they allowed for more URLs processed per month, but it helps that they have the cheapest CPLI. I initially thought SenukeX Xindexer was going to dominate everyone since they came so strong out of the gate. It’s also worth noting that SenukeX has been over optimizing its Indexing service since launch and will most likely not have as good of results once they hit capacity. But, if you already have the software and only need to index a small amount of links per day then this is a good option. Nuclear-Link-Indexer.com looks to be a pretty decent service too, especially in the beginning, but they hit a plateau and didn’t ever get going strong again. Also, since they aren’t using the backlinks to backlinks method one has to wonder if these links will fall out of index easier or if they are “juiced” very much at all. I do like how they check your URLs for errors and active links before processing though. The indexing report dashboard is nice (although slow), but I’m sure most of us use ScrapeBox anyway. LinkJuiceMaximizer.com shows marginal results which looks to be about what most users of their service have been voicing concerns over for a while. Linklicious.me is not marketed as an “Indexing Service” per say but I wanted to include them in this test since they are commonly used. They deal with bulk URLs so based on that criteria I say they do a decent job at what they set out to accomplish, but clearly, pinging alone doesn’t result in getting backlinks indexed. Their CPLI is still super low (2nd place overall) because they have a very cheap price for the massive volume of links they allow per month. Backlinkindexing.com started out really slow but started to pick up some speed towards the end. As it currently stands their CPLI is the highest of all the services compared. Indexbear.com really surprised me especially since they just finished revamping their system. At first it seemed they were doing nothing at all to get these links indexed and then by day 10 we saw an exponential period of indexing growth. Unfortunately for them it is still very low when compared with the other services. Indexbear finished next to last in this competition (right in front of Linklicious) not to mention that they have the 2nd highest CPLI as well.


Final Words
These are the results of one man (me) and are not meant as a promotion for any of the aforementioned indexing services. I am merely illustrating facts so you can make the best informed decision for yourself and your budget. I am continuing my analysis of this study still and may post follow ups as time goes on. I am obsessed with statistics and I encourage you to conduct your own tests if you have any doubts as to the validity of my findings. I am brainstorming ideas on how I will conduct a case study on the effects of getting backlinks indexed and how it correlates to SERP improvement. If you have data you can share we can all benefit from this knowledge.
