So, you've probably seen a lot of articles on EZA or wherever that keep repeating the keyword phrase over and over again like a demented parrot. It looks ugly, it doesn't make people think they've found some advice they can trust (and so want to clicky on the linky at the bottom) and it doesn't work.
Instead of repeating the same thing to the point that it doesn't look natural, here's a quick tip to get the phrases in there and not drive everyone crazy. Search engines parse text and strip out the punctuation line breaks and stuff, so they'll read two sentences seperated by a period or whatever as one string of text.
"These days many people are looking for free edible panties. Free edible panties are really great because they're fun to use for both of you. So how do you get free edible panties. Well, the first thing to do is..."
So what's all this talk about free edible panties? The first thing is it's super fun getting things for free. Edible panties are a great way to get the vitamins you need while having some fun, am I right? When you've got a couple of hours free, edible panties can make the time fly.
I did this off the top of my head, but with more thought it works better and reads more naturally and still gives you the keyword phrases in the article without sounding like a demented parrot.
