What exactly is "the same keyword twice"?
I have yesterday bumped into some WA advice, about targeting the same keyword twice.
It's said that we should avoid the practice, as it adds no value to the website, and may actually hurt our rankings.
The reason I am worried is that at times, I have had articles that are 4000+ words. And I have broken them down into two.
Sometimes I have used the same title, adding "Part 1" and "Part 2". Sometimes I have used different titles.
EXAMPLE: I want to help people with First Aid for common household trauma situations.
I create first article, "First Aid for Burns" and second article, "First Aid for Any Form of Choking". Alternatively, "First Aid - Part 1" and "First Aid - Part 2" and deal with Burns and Choking respectively.
But does it matter? My concern is that this could be the "one keyword twice" that we are advised against.
How does one work around the problem of breaking a lengthy article into smaller pieces?
Or what exactly is "the same keyword twice"? Does the above First Aid example fit the description?
