If I had to start over again I would do the same thing:
– Watch hours in YouTube from a handful of people.
– Get started and pivot for the first few weeks.
– Join /r/juststart and learn from journeys
SEO best practices change yearly/monthly. It depends on who you ask. But if you start and make it a habit to keep learning over time you’ll be in better position long term.
Get started and pivot until you have something to be proud of.
