This truly amazing and I’m gonna share this with like minded people. I loved the part about flippa. What a great source to get ideas. Building links tends to be the hardest to do, but a few good quality links is all you need now a days to get ranked. I currently rank for a very high volume keyword with only 5 links all with pr 3,4 and good DA and PA. Good links are hard to get but you only need a few which is encouraging! Props for this post!
Lastly, it's important to remember that paralysis by over-thinking is a real issue some struggle with. There's no pill for it (yet). Predicting perfection is a fool's errand. Get as close as you can within a reasonable timeframe, and prepare for future iteration. If you're traveling through your plan and determine a soft spot at any time, simply pivot. It's many hours of upfront work to get your strategy built, but it's not too hard to tweak as you go.
