Way back, at the beginnings of SEO, it had nearly always been about keywords.
When we prioritised keywords over content quality because, after all, that’s what it took to get ranked.
A world of quantity over quality, it did not really matter if the keywords we used sounded surgically implanted or not.
We all knew that it worked, so went along for the ride.
Just like VHS has gone, (I remember when the best Video store in town folded). It is no longer about using hundreds of keywords.
Just like the slimline blu-ray DVD has replaced the VHS recorder; natural use of keywords in content is the way forward.
We live in the modern, reinvented world, where semantic search makes a major impact.
