Is it good for search engines to use variations of words in your articles? ie, child, kid, baby, toddler, infant What if this dilutes your main keywords? Does this matter? And what about possessives, ie children's, does that screw it up too? What about motivates, motivation, motivated, for example, are they best avoided?
IMO, it really doesn't matter, just as long as you include the target keywords a few times in the article. If you are writing for humans and not search engines then you will naturally include variations of keywords in the article anyway.
yea you can do this for the different results, but if you type your searching keyword in inverted commas you will more of the specific result for the keyword you are searching for.Either you can also type a phrase fpr your search.
Oh yeah.... here is a tip. Type this in the google search box: ~"keyword". The search results will show related keywords in bold, which helps with keyword research.
Just target your keyword, and make it as human readable as possible so people will get something out of the article. synonyms/variations won't help optimize for your keyword.
Yes go for different variations as every keyword has different competition and search volume. Try creating and combining theme based keywords.
