Google is doing that on purpose to tell you one thing:
- Pay us money or you ain't gonna appear under your beloved queries with your large number of pages.
There are 2 resolutions:
- Pay them money by either creating a blog network with good domains or pay them directly via paid ads system.
- Switch to their other properties like YouTube which is also a search engine.
Instead of digging yourself deeper in mould like many people do, see this is horrendous situation and corrupt system where there's no simple solution for.
If you start to depend on indexing services, you'll be playing a cat and mouse games with providers, google and sites to index. It'll be counterproductive and will not let you grow long term.
The times where you could get free money at insane ROI have ended. Their true nature is here and now - this is a giant that nobody small should think of if they want to maintain any reasonable, non-negative returns. It might have been planned 20 years ago.
They first hooked people with "free money", but what people need to pay now? Many become dependent on their system and have to pay for their trust to a stranger. Now people are their product, although they thought it's not the case. Such businesses are trojan horses played long term.
Anyways, if you want to continue with them, you should think of three options:
- Doorway pages. See which sites index once you setup them. Try free web 2.0 blogs. Build them a little bit and blast them. Although you'll probably fail 50 times first 2 years.
- Black hat niche sites. Virtually there's no competition under those queries. Everyone just quit and there's a large sea of black hat keywords people try to rank with parasite SEO (which doesn't work due to increased moderation these days). A $100 domain may work, but it has to have some large amount of pages indexed already, so it has some "reputation" or whatever they call it.
- Build 50 fresh sites and add some PLR content mixed with fine-tuned model and RAG. Once you add 4000 pages over one year, at year two blast it with 1 million pages. Probably waste of time anyways.
I'm not doing any of that cause it would lead me to doing something for 2 years... you see, it doesn't make sense when you have social media and 50 views in the 1st hour of publishing content.
