Why is my business getting little to no traffic?

I'll tell you this, is what you're providing of some value? Are you actually selling something that people actually need, what need are you fulfilling, because I can tell you this, I've never done an intro like the ones you show in your webpage, I've never done an intro in my life, but I can tell you this, I'm aware that you can do those intros really easily, in fact I'm pretty sure I can do it within 8 hours even less. It looks like your targeting towards people that do videos for YouTube or something similar, I'm pretty sure most of those people are broke students from 15-22 who do YouTube as a hobby and are just starting out and they would rather spend 8 hours finding free tutorials on how to make an intro than pay $60 dollars. Don't get me wrong I'm not shitting on you or your business, you're actually doing better than 99% of people because not only did you actually thought of a business idea, but you actually went out there, took action and tried it. I think that you actually have to provide more value than most of the people who are into this niche provide. If you're actually good in this, why don't you contact some small Youtubers/vloggers with maybe 10k subs, and offer to do an intro for their YouTube channel for free, don't even ask for a shoutout, just do it and blindly trust they will shout you out in their description, don't even expect a 15 second shoutout in the video, you have to trust that eventually someone is gonna give you a 5 second shoutout in a video and then you will get some potential customers from there, even if you don't get any customers you can use the intros you made for those people as a reference for other people to trust you in your website. It's a win-win either way for you and for everybody. If you're not getting anywhere within 6-9 months you might give yourself a chance and THEN consider leaving that business idea and move on to another one. So in short, why is your business getting little to no traffic? You can always increase a little your traffic doing some basic SEO or doing Google Adwords or Facebook ads, but you can always trust that if you're not providing any value, your business doesn't fill any need or simply your business main idea sucks (I'm not talking about your business, I'm talking in a general context) you're not gonna get anywhere even if you were to get 5k people visiting your site daily it wouldn't even matter, because you wouldn't get anyone to pay for your product because it simply isn't of any use for them.

Twitch and Youtube have a large population with a high demand for products such as yours. You could easily stream design sessions to both. A form of advertising while you work in a sense. I also noticed your missing a lot of potential draw on youtube. Your lacking key information for advertising your services. For example, a link your website or perhaps a link to purchase that specific into/outro. Youtube and Twitch can be big draws for traffic. Utilize them heavily.

In my opinion your target audience is basically Youtubers\Streamers. In addition your entering a very saturated market. It could take some time to build a following.

Your marketing is akin to throwing a single lure into the middle of the ocean and wondering why you haven't caught a bunch of fish yet. Yes, there are a lot of fish to be caught, but you're not catching them. You need to better target your marketing to people who have the money to pay, and need the services (sticking with the metaphor, change the bait you're using - to one that will catch you more fish).

I'd recommend picking up Seth Godin's book called Tribes and maybe even Guerilla Marketing by Jay Levinson to help dial in your approach.

Hope that helps.
