Keyword Depreciation, Should I be consirned?

Hey

Lets say you create a website about motorbikes. The index file will have motorbikes as a keyword.

But what if you create a second page (on the same site) using motorbike parts as keyword

Will google pay less attention to the keyword motorbikes as it's used in multiple pages?

You don't need to worry much if the obviously keywords are related, and probably not at all if you are dealing with plurality.

yea dont worry about that. no one really knows how google really works and it will change in the years to come anyways. just use common sense and you will be all good.
