Yes SEO is very much a thing. We are in a very crowded space (who isn't these days) and got one of our articles that was written about 5-6 months ago now appearing in top 5 results on Page 1 for that keyword which has decent volume. So it is definitely possible. But we didn't just SEO it. We actually wrote really good quality content with lot of valuable information and google is smart enough to rank it well after a few months. So, the trick is to be patient and do quality work. It will show.
