Once upon a time, On-Page SEO was blogger's bread and butter.
The idea was simple, use as many as targeted keywords as possible within the content, meta tags etc. and with few backlinks, your content will rank number one on Google search rankings, and you will get tons of traffic.
And It was true.... for a while.
Now here is an interesting question....
If you publish a post stuffed with keywords now in 2019. Will it rank number one on Google?
The answer is no. Absolutely NOT!
