I am answering random questions today...
(NOTE: This question, and my answer, is referencing a software program, "Brainstorm It by SBI", that both me and the question asker use.)
For some reason, this thread was showing up as a "recommended" thread at the bottom of the new BrainstormIt update thread, for me. It's an older thread, so not sure if you (the OP) are still watching it for answers or not, or if you've found your answer yet, but I did not see it when it was originally posts, only just saw it now, so, I'm answering it now, though, might be too late for you to see the answer.
I am myself dealing with a super tiny niche, smaller in fact then what you've described with yours. Here are some of my numbers:
And those are the ones Brainstomer said are the "most profitable" LOL!
If you are wondering, my primary site concept niche topic is "writing dark fantasy yaoi novels" or "how to write dark fantasy yaoi" or just "dark fantasy yaoi", however, because I'm an author (of Dark Fantasy Yaoi novels, focused on a trans uke x dom seme relationship, with the uke being an Elf and the Seme being a Vampire-Lich-Unicorn) and it's an author homepage, my url is my name and not my keyword. This was decided upon when I realized my name ranked WAY higher in the search/demand then any of the site concept keywords.
Sidenote...as of right now, today, my name gets searched for an average of 17 times a day, all 17 of those times resulting in clicks to my home page (that statistic is according to Google Site Analytics Search Console Dashboard)
In other words, my name (EelKat) was searched for 472 times in the past 28 days; whereas my site topic keyword (dark fantasy yaoi) was only searched for 25 times in the past 28 days.
Let me translate what those numbers mean...
means that in the past 28 days the keyword "bl yaoi" was searched for 502 times, but there are only 10 websites using that keyword...meaning if I use that as a keyword my site will rank minimum #11
That one website, is the SAME one website every time (I checked) and you want to know what site it is? FanFiction.net itself.
Meaning my primary #1 competitor is one of the single, largest, most trafficked websites on the planet, that rivals Wikipedia and Amazon is Alexa rankings... BUT.... they are also my ONLY competitor, meaning if people can't find what they want there, my SBI site it their ONLY alternative.
What those Supply numbers mean for me as a content site web builder, is that I'm pretty much guaranteed to rank at least #5 and probably #1 of page 1 of Google for every single keyword on that list, within hours after publishing a page focused on each of those keywords.
In other woulds, the supply numbers are super because the lower the supply, the better chance you have of reaching the top in search results.
Getting to #1 slot of page 1 of Google is only half the battle...getting traffic to your site, is a different thing entirely.
In my case (and your's for your topic) the top 100 keywords all have a demand under 50, meaning fewer then 50 people searched for those keywords in the last 28 days.
What that means is... at MOST my site is going to get 50 page views PER MONTH.
If you are relying on AdSense, Affiliate Banners, or Amazon Affiliates for income.... you'll be lucky if you see $10 a month, with demand numbers that low.
So, how do you deal with this?
Well, in my case, what I do is I focus on the primary topic keywords, BUT, if you look at the list Brainstomer gave me, you can see quite a few places I can expand.
Have both high demand and high supply. Meaning I don't stand a chance in hell of ranking very high in these, however, I have a better chance of getting traffic from them, just due to the sheer amount of people searching for them.
Using any of those words as a primary page topic is not going to do much over all, but, using those words as secondary keywords in the body of the OTHER pages for my primary keywords, helps those pages rank, in these keywords in addition to ranking for their primary keyword, which in turn increases traffic to a page that normally would get fewer hits.
In other words, on a page like:
mentioning the words "romance novels", "yaoi", "vampires", "gay marriage", and "dark fantasy" throughout the body of the article, puts the page in keyword search results for all of those keywords, not just it's primary keyword.
But don't just add words at random. I chose those words as an example, because in the particular series I write, one of the characters is a vampire, and it is a gay couple in a romance story, that features the topic of gay marriage. So, those keywords fit for the page in question and are words that are natural to the text and not added just for the sake of adding them.
In other words, when you have a low demand keyword, research to find on-topic high demand keywords that compliment it and will help drive traffic.
Likewise, take keywords like these:
Those all have mid-high range demand, but low supply. And they are all on topic to the page mentioned above.
So, now I'm able to write a page with the primary keyword of "vampire yaoi", and it be a page on "novel writing help" for "writing fantasy books" dealing with the topic of "male pregnancy" (yes, that's a thing I write about - my main character has been pregnant twice now and he'll likely be pregnant again in future novels - I told you, it's a small niche with not many followers)...and it's still about writing "romance novels" featuring "vampires" and "gay marriage" in a "dark fantasy" setting.
So, do you see what I did there?
I now have a primary keyword that is guaranteed to rank #1 on page 1 of Google search results, but only had 34 people searching for it in the last 28 days, but also features a keyword that had 45k people searching for it, and several keywords with 1k to 2k people searching for it.
This results in the page showing up in search results for ALL of these keywords:
To rank with that many keywords also requires your articles be 3,000 to 5,000 words per page MINIMUM because you'll need your primary keyword at least 20 times, twice in the first paragraph, once in each heading, once in each image title, once in each side box (call out ect), and then once in each paragraph, but no more then 10 times per 1,000 words. Then each of the secondary keywords, 4 to 7 times total on the entire page in the body of the text.
If you tried to do that on an article shorter then 2,000 words it'd been seen by Google as keyword stuffing.
(by the way, most pages on my site are in the 7,000 to 10,000 words per page range)
Next, using a site topic with primarily low demand keywords, requires you to have a LOT of free time to focus on your site.
Because, a site with only 50 to 100 people (or fewer) on the planet searching for it, means, you need to give them A LOT of pages to keep them coming back.
If you only have 100 pages on your site, and there are only 30 people per month searching for your topic, that means you are going to get at best 3,000 page views per month, and may only be getting 100 page views per month.
The smaller the demand is for your topic, the more pages you need to produce.
You need to ask: Am I looking to put in 2 to 10 hours a week or 2 to 10 hours a day?
I work on my SBI site about 8 hours a day 5 days a week, in case you were wondering. When you have a niche this small and a site this big, you kind of have to.
Now, in the case of my own topic, I'm dealing with a novel series that has 130+ volumes, 75+ characters, features time travel to dozens of eras, has characters traveling to all points of the planet, and includes space travel to alien worlds as well. Plus sample chapters of each novel are on my site.
This means, I can create literally THOUSANDS of pages for my SBI site.
Plus I am swamped with emails from my readers/fans of the series and I try to answer at least 1 reader question a day, those posted on my site as well,
Then there are all the pages featuring the video interviews where I visit the actual locations you see featured in the novels.
My site ends up not just being about Yaoi, but covered too, every aspect of the career of being the author of a long running Dark Fantasy Yaoi series.... so there are also pages on how to format the novel, how to edit the novel, how to publish the novel, how to market the novel, where to find ideas for the next novel, how to juggle daily life with a novelists career, pages on what it's like going to conventions, meeting fans, doing book signings, etc.
Completely unexpected was the series of pages on dealing with hate groups and the Ku Klux Klan after they attacked my family, blew up our house with a bomb, kidnapped our cats, murdered our cats, and now I've got a series of pages on what it's like working with the FBI to bring down a gay-hating terrorist group, as well as pages on how to deal with the court cases and grand jury trial that came with it.
Basically my site is a look into the every day life of an author of gay erotica and things we authors of gay erotica have to deal with as part of our every day life... all that came from the primary site concept of "writing dark fantasy yaoi"
You are probably starting to realize why I have 9,772 pages now, right? (Only 1,370 of them are currently on my SBI site as I'm moving them from an old site hosted on WP... if you have a huge site, avoid WP, their servers can't handle it and crash constantly... stable servers able to support a massive site with zero downtime is why I moved to SBI)
My point is, while you have the one primary site concept topic keyword... that one topic has lots of sub topics inside of it. And over time, new sub topics you never dreamed of will pop up.
10 years ago, if you had told me my site would include a section on how to deal with the Ku Klux Klan attacking the families of authors of gay erotica, I'd have laughed and said you were nuts. But that is now not only a topic on my site, those pages are my most trafficked pages of all, AND, I'm finding out because of those pages, that the KKK attacking authors of gay fiction is actually very common and very wide spread in America... you'd be surprised how many THOUSANDS of gay erotica authors have contacted me to say they gave up their careers as authors of gay fiction in order to have peace and safety for their families again. Terrorist attacks again authors of gay erotica is a big problem in USA and no one talks about it so no one knew it was going on. I'm the first author who dared to speak out on what was being done to my ffamily, and now other authors are coming forward saying, it happened to them to and they were too scared to even go to the police about it.
Never be afraid to expand your topic to it's unexpected sub-topics, you never know who you'll end up helping.
And, there is likely a reason not many sites are there to supply content for the demand. Low demand and low supply, usually means there is not much money in the topic in question, thus why so few sites to supply for the demand.n
In other words, if the supply is only 4 sites, that likely means those 4 sites are run by an uber fan of the niche who is likely doing it purely for the love of the topic and is not making much if ANY income from their sites at all.
Topics that are over saturated with supply, means it's super easy to monetize, so every one and his cousin is trying to cash in on it.
Topics with almost no sites supplying means that in spite of demand, there is no easy way to monetize this topic so no one bothers to focus on it, because most people build a site looking for easy cash and rarely do they have any real passion in their topic at all.
What this means is, not only do you really need to love your topic and be able to stick with it, but you also need to do some heavy duty research to find methods of monetizing it.
Now, me, I knew going into SBI, that my topic had almost no traction. I knew that because I started my website back in 1997, for a genre that I started writing in 1978. My site has changed web host multiple times before arriving on SBI in 2013, so I knew from experience the type of traffic my site could expect and the difficulty I'd be faced with in the lack of demand.
But... this is my career. My topic, is my career. Writing Dark Fantasy Yaoi is my job, my passion, my obsession. It's what I'm gonna do wither it makes money or not, so I might as well go ahead and try to make money with it, right?
But the question of monetizing my SBI site, does come into play here. I'm dealing with a topic with practically no supply and almost as little demand, and no affiliates for it, and not enough traffic to make pay-per-click a big income.
So, what to do?
In my case, make your own product. I sell my books, my art, etc.
Most of my income comes from sales of my art.
Most of my AdSense income comes from views of my interview YouTube videos embedded in my site.
Most of the affiliate sales comes from promoting CosPlay supplies, for people who like to dress up as their favorite Yaoi characters.
When you are dealing with a super small demand niche, you need to really know your audience well and ask yourself: "What will they buy?" And then find that product to promote.
I've been in this niche for 4 decades, so I know it really well. I also know that it has about 7,000 hobbiests/participants world wide. All 7,000 of them follow me on Twitter & FaceBook since 2008 (I have around 10k followers on each)
Because my genre is so small, but also so devoted, I can pretty much guarantee that every book I publish is going to do this:
So the first few weeks my books are rocking the bestseller charts on Amazon and by 6 months after publication they are bottom feeding at 500,000 and by the end of year 2 they are mired up at 2,000,000 sales rank.
If you are a Kindle Author you know those numbers are really bad... if you are a Yaoi author, your bug eyed and jaw dropped and asking: "How the hell did you get numbers that amazing high?!?!?" In spite of those super sucky numbers, I am in fact the top selling author in my genre, which tells you how shitting the numbers get for the other authors in this field.
It's not easy to make a full time income on sales of Yaoi books alone. That's where art sales come in, and affiliate sales to costume supplies.
Well, in the end, you can see, how picking a site topic that is very low demand and almost no supply can translate into your needing really big passions and the time to do a lot of work on the site.
For me, there was no other choice, no other site topic, no me searching to see what topic was best for me, because, this topic is my career and my passion and my life, so trying to do any other site topic was absolutely out of the question.
I am always of the belief that if your topic is your passion, then you will find a way to make it work regardless of what the numbers say.
Not sure I answered this part, I meant too, so adding it now...
The reason is because it means your keyword was only searched for a total of 50 times in the last 28 days... meaning your site will get at MOST 50 page visits per month, but considering fewer then 10% of searchers are going to click to your site, that means...
This is the reason for striving for 20,000 to 60,000 demand range.
What do you want to become?
What did you do today to step closer to that goal?
Whatever you do, be your best at it!
And remember to have yourself a great and wonderfully glorious day!
