Indexation rate has nothing to do with if a service works. If i make a bunch of web 2.0 and say a magic spell I will also get a certain percentage indexed. Google crawls aggressively.
The real test is if I make a completely isolated page on a never before seen domain/page. A website with 0 backlinks from elsewhere on the internet and with no way for spiders to reach it 'naturally'. If an indexing service can't get google-bot to visit this kind of page then i consider the test failed and the service not working. Some services literally instantly bring spiders and others never. Those were my findings.
Was my intention to re-test everything but have been occupied with other things. I'm hoping to do a full re-test with accompanying video and in depth explanation of how i'm monitoring spiders before the end of the year.
Your point about "indexation rate has nothing to do with if a service works" is stupid. It has everything to do with an "indexing service".
Excuse me for pointing out the obvious here, but if a service states its an indexing service, then this would mean that it will try to get your urls
indexed. What you are getting confused about is 'crawling' service to an 'indexing' service.... completely different thing here, any idiot can get a spider to a page, it would be pretty stupid to "
The real test is if I make a completely isolated page on a never before seen domain/page. A website with 0 backlinks from elsewhere on the internet and with no way for spiders to reach it 'naturally'" why would anyone do this for SEO purposes? The entire point is to get link juice flowing to a back link in order it to be beneficial for the page it links out to and when you submit this page to a service, depending on the method the services use, there will be links pointing to it albeit a url or a ping a path will be created.
There are two main types of services available, an indexing service, which is generally a little more expensive and a crawling service, there wouldn't be two different types of services if they didn't both do different things, if you would like your googlebot visits and don't care for actual index rates, then go for the cheapest crawling service there is and make sure you get your googlebot visits but if you're wanting to actually unleash the pull potential of your link building expenses, then go for an indexing service.
You can't know the inner workings of each indexing service out there to make a conclusion on if one works or doesn't due to spider visits and then have the audacity to preach this shit to newbies, it makes me laugh, even more so after I tested it myself from the results you had given and found completely contradicting results, regardless of the services I personally use, it's false information, full stop. A crap case study.
Back to indexing services or crawling services, personally, you'll be wasting your money on a crawling/pinging service, you would be saving each month if you just pinged your backlinks yourself once per week because that's all a pinging/crawling service is doing, you could rent a vps for $5 a month and do this on autopilot... or even simpler, use something like pingomatic and compile an rss feed with your backlinks, it'll take seconds and you don't need to pay for a crawling/pinging service like indexification or others similar.
If you do want something to increase index ratios and most importantly, the speed your new links are indexed for SERP purposes, then with the money you save from not using a crawling/pinging service, get yourself an indexing service instead, do your own testing with which service you find to be more effective.
