Do you perform SEO now? Do you have a long list of clients who need services? Do you have answers to questions about SEO so you can properly manage a team? Do you have proof that you are better than any other high school drop out that claims to be an SEO professional? Do you have some X-factor on your side that makes you already a better choice than the 1000’s of agencies in your county/region?
If you can answer these questions then I think you should base your answer on that.
It IS CROWDED. Also, to be a legitimate SEO, you need to actually do legitimate things. It’s no easy road to riches. If you need a startup idea, I can probably give you two hundred better ideas before lunch, and lunch in in 15 minutes.
It is also a situation, where I think if you are talented enough to succeed in the SEO space, you would also be talented enough to know how to answer your own question. I mean that in the nicest possible way.
Sometimes I wonder if questions like this one, is just me being trolled by some bot on Reddit.
