Before we get into the meat and potatoes of cloaking keywords, let's remember why your keywords are as important a topic as they are. And they most certainly are.

A quick check on Google reminds us that keywords are: "Search terms or phrases that are related to an advertisement or ad copy."

And also "Words that may be used by viewers searching for information."

That makes YOUR keywords VERY SIGNIFICANT. Info seekers are out in cyberspace typing in those keywords and the search engines are trying to reward those searches. And the more precisely you infuse your articles with those keywords (in essence, the better you 'cloak' your keywords...the much better your article results will be.)

What's the need for this cloaking business?

Good article writers, and certainly good copywriters, know that weaving their keywords (or 'cloaking keywords') takes the ugly SPAM moniker off. The best of the best of these writers cloak their keywords by delivering them NATURALLY. So as NOT to call attention to them.

Here's a perfect example of someone writing an article about "the horrible effects of cheddar cheese" (which is 1 keyword don't forget) THE WRONG WAY:

"The horrible effects of cheddar cheese can be found everywhere. Sandwich shops, fine eateries...etc."

By putting the keyword first in the sentence, especially first in the sentence of the first paragraph of your article you make it beyond obvious. Why not put some police tape around it? How about one of those movie spotlights that you can rent for parties.

That'd be less obvious.

Simply by finding ways to insert your keywords into your article where they fall more toward the ends of sentences will help tremendously. Place your keywords in the middle of your sentences and find unique ways to 'write into' and 'write out of' them.

Here's another side benefit: cloaking keywords WILL MAKE YOU A BETTER WRITER. If you're continuously looking for better and smarter ways to professionally 'hide' them, you will start using different forms of writing techniques that you may not have before.

Plus it can be a lot of fun.

Now, am I going to wrap this article up with a keyword at the end and make it deliberate and obvious?

Nope. And done well, you won't have to either.
