The "Sherlock" Strategy vs. The "All in all" Strategy

I distinguish SEO campaigns into two categories. 1/ The one for all, all for one technique 2/ The Sherlock Technique (my favourite) The first one is doing everything and anything that might seem to work. Going for every keyword that seems possible to rank. Pursuing every tactic that competitors seem to be winning with. Basically being open to anything, going after all audiences: the individuals, the businesses, the buyers, the lookers, males, females – everyone and their dogs. Being active on every channel from Facebook to TikTok. I call this the "all for one, one for all" technique. On the other hand, there's a different SEO campaign where you focus on one audience and one strategy. It doesn't matter how hard it is, how big the competitor is, or how high the CPC is. You go in for one audience with one goal in mind, execute one strategy, and do it very well. I call it the "Sherlock Strategy." Remember the "Science of Deduction"? I think we need this kind of clarity for SEO campaigns. SEO itself takes comparatively longer to see results, and jumping from tactic to tactic and audience to audience will take us nowhere. Whenever I start a new SEO campaign, I don't focus on what I can "do"; rather, I eliminate what I should be avoiding. The remaining options become obvious. Again, the science of deduction.
