You posted the same version of this advertisement on r/entrepreneur yesterday, Subhash -
https://www.reddit.com/r/Entrepreneur/comments/avql1e/everything_has_been_already_done_to_death/.
This entire essay is nothing but an ad. We get it - you're working hard to promote Rankz io on BHW as you did on Detailed.com.
You run an SEO agency firm in India so it might be easy for you. But, for the average newbie, ranking on Google isn't as simple as building a few backlinks and rippping content from some site they saw on Flippa.
Why everything has to be so black and white ?
Now since you mentioned reddit, just go through that thread there and see how many people actually benefited from that "AD" essay and they acknowledged it openly. They had some ideas but they were not doing it because of the usual competition fear, if my post helped them overcome it and move ahead, even if 1% of them makes it, I will be glad i posted it.
On BWW, I added value, check my past history, created a
top post of Week with exact Keywords I used, 100% honest earning data and the exact method I used with 0 mention of my product or even an outbound link. Tell me how many you see that kind of stuff ?
Now when I try to take some value, everyone have problem with it ? I am no pushing something down someones throat, it was a simple mention with no zazzed up buzzwords or anything, I asked them to check out what i am working on, try it out and if they like they can buy if not continue with their day to day life..
I don't earn by the number of outbound clicks to that link, I make money only if I am able to convince the users, after a long 7 days trial that the product is worth it. Only and only if People see value in the product, they will buy it. I am not selling a damn 7$ ebook which promises to make you millions in 2 weeks or a push button Money Robot which will solve all your Money problems for just $39 a month , I am selling a tool which is a must have for any SEO, they already use it from somewhere else, I am trying to get them to try mine.

"But, for the average newbie, ranking on Google isn't as simple as building a few backlinks and rippping content from some site they saw on Flippa"
The same average Newbie is fine ripping off "Paid" courses, "Paid Softwares" , and "Paid themes" from people who expect people to pay for it, Just look right here in the Left Sidebar and how many thanks each of these posts gets but that noob dude has ethical problems in taking inspiration from a blog's keyword or take inspiration from the content. These 2 things is already public.. And let's be honest here , almost every niche or keyword you are trying to rank for, is already done by someone else in past right ? is every single affiliate or adenines site is a work of theft ?
Also, Every single time the same noobs run their BH tools, it goes on the web, rips someone's content from a directory, spins it off and then post on someone's websites. isn't thats how BH tools work? no ethical issues with that either , they go on boasting how great their GSA settings are and how great their Article scrapper works.
Making money on the internet is difficult, very difficult, it's easier to fall for gurus who sells you a dream instead of doing the hard work it takes. I have been there, wasted lots of money in WSOs, and then finally started with copying others keywords (Every freaking keyword is already being done by someone else anyway so I highly doubt if someone is doing a "Original Keyword" here ), made my first $1000, moved on to research more and invest the money I made into better tools and content and made progress.. Took me almost 8 years to be where I am today.
(I could link to interview where i talked about my journey and what it takes but people will flag it as a self promotion again

so let it be.
The SEO agency you mentioned, was probably 20,000th SEO agency in India, Yet i was able to get some of the biggest brands most guys can only dream off as clients. You already know the website, feel free to check the client list or check the revenue on MCA.
From inside the agency, the 1st blog we built was in Fitness industry, would be probably 300,000th Fitness blog, and yet you read the case study on detailed, it was for real.
We build couple other sites I wont name which were course not the first in industry and made tons of money with it.
The current tool I talked about is not the 1st and won't be the last but almost everyone who uses it, appreciates the experience. We have steady flow of users coming in, mostly from the content we create and the tools we give them.. Just 3 days back we gave our Facebook community a tool to check Domain Availability of 20,000 Domains in shot , takes about 40 seconds to do it, for Free.
Some treat those as valuable , some treats those as Ads.. it's an individual's choice and I respect it.
