[2024 BHW Indexer Study]

You shouldn't need this type of service for any real semi-decent website. As it will be automatically indexed every few days worst case. It's really meant for the black hat links that you build that you might direct towards your site in the end.
Thank you for you answer ! I understand now this type of services
 
Can you add 2index.ninja to your list and check it out? I've been using it for a while now and it shows great results. But you don't have it in your list.
If they're still advertising on the forum the next time I update the study, they will be included. But I'm not doing updates on demand.
 
Can you use Link indexer for your money site?
They shouldn't really be needed for money sites. That's what internal links and proper backlinking to your prominent pages is for. A few urls here and there are ok, but if you find yourself needing to index lots of pages on your money site via an indexer, that usually indicates that you need to revisit how you are handling your internal linking, and how your pages/categories/products etc are grouped together for easy access.
 
Is "indexinject" not indexed at all?
In my tests from earlier this year and in 2023, the urls I gave to that service received no Googlebot visits, resulting in no indexing/caching.
 
Here is the 2024 edition of a study I seem to be running yearly since 2022, testing every current indexing service that promotes their wares on BHW. I use orphaned pages to run these tests, devoid of any internal/external links or entries in sitemaps, as there should be no way for spiders to reach these pages without a working indexer notifying them of their existence. I've gone one step further this time, and I'm now tracking exactly if and when Googlebot visits these orphaned pages.

I set up pages on 5 domains that I own, 1 page for each indexing service. These pages have no internal or external links, are not included in any sitemaps, and have only been visited via a de-Googled Chrome browser. Each page has 500+ words of complete garbage auto-generated but unique content. The sites on all the domains were already naturally indexed before commencing the study. I'm tracking any visits from Googlebot via the access_log for each domain - no third party stats packages, straight from the main data source.

As of Jan 2024 when I started the study there were 10 providers offering indexing services in the BHW marketplace.

I tried to contact this service: https://www.blackhatworld.com/seo/ultimate-backlink-indexing-service-discounts-available-pbnhosting-io.1533397/
But received no reply, and their sales thread is now closed, so they're excluded.

All new accounts were setup to conduct this test. No 'free credits' or any other offers were used, all paid accounts.

How am I checking indexing?

I'm using two different searches to determine whether a page is indexed:
site:domain.com/page and cache:domain.com/page
The first operator is the one that most use to check indexing, the second I use as I find a cached page tends to stick around in the index longer. Results will be shown as either a green tick indicating the url was present, or a red cross indicating the url was not present. So ✅❌ would indicate that the url was found with a site: operator but not a cache: operator. I tracked indexing every day for a week, and then followed up in 1 week intervals until 28 days elapsed. Time began when the urls were submitted to each service. No 'drip feed' values were given, I went for whatever 'immediate indexing' option each service had.

Conclusion

I'll leave that down to you guys, as they all have different price points, speed and reliability.

Additional Information

Services capable of indexing .pdf files: AddToIndex (~14 days), Linkdexing (~14 days), PageIndexer (~2 days), and SmartIndexer (~2 days).
EliteLinkIndexer did send Googlebot to some other orphaned urls I was testing it with, but not the ones I was using for this study unfortunately.
SMMTribe cancelled my indexing order and removed the indexing service from their services list some time during the study with no notification given.
A mix of indexing techniques seems to be made by all the working services.
Linkdexing sent the widest variety of search engine bots (Bing, Yandex, TikTok Bytedance spider etc)
nice case study

can you share more details of the sites/niches?

Each page has 500+ words of complete garbage auto-generated but unique content. No specific niche, just garbage. The thinking is that if this very low quality gets indexed by a service, then it should work for most other cases (as long as there are no other barriers to indexing).

very interesting
i wonder if the same study but with professional, human writing would change the indexing

because we know even in garbage there are classes, so it depends of what kind of garbage the site content is about.

is it only words? random characters? words from several languages? complete sentences? copy/pasted content from somewhere?

that could be interesting to see if google really cares about content quality or it really doesnt give a damn and index rate is the same, regardless of content quality

I've attached a sample of the content I use when conducting these studies to the thread. As you can see, it's complete nonsense.
