The Magical Keyword Density Formula

Keyword Density

When it comes to SEO copywriting, this has to be one of the most talked-about subjects. Why? Because keywords are the very foundation of search engine copywriting. Without keywords we wouldn’t even have SEO copywriting. Since keywords (or more accurately, keyphrases) play
such an important role in search engine copywriting, it would make sense to have certain rules and regulations or formulas that should be followed.

It might make sense, but I’m sorry to say the mystery… the magic… is more like a myth.

I have a guess as to where these magic formulas come from. Someone brags to their friend that they got a #1 ranking for a particular keyphrase. The friend studiously looks over the site and starts taking notes. “He used this phrase 8 times in a 500-word piece of copy. He put the keywords here and there and over here, too. That means you have to put keyphrases in these places and reach a keyword density of 1.6% in order to get a #1 ranking.” Not so! Let me
explain why keyword density formulas don’t fly.

Copywriting Is One Piece of the Search Engine Optimization

Formula Copywriting, in my opinion and the opinions of respected search engine optimizers, is 1/3 of the puzzle; but there are other pieces to the puzzle, too. What about coding and linking? Those are two extremely
important factors that also come into play.

If copywriting were the sole factor, then maybe — just maybe — keyword density formulas might be a reality instead of a fable. But alas… they aren’t.

Keyword Density Formulas Are Unproven

Go to any search engine and type in your primary keyphrase. Look at the results that fall into the #1 through #5 slots. Do they all have the same keyword density? No. Some have higher levels and some have lower levels.

If keyword density formulas were carved in stone, every single site in the top 10 would have the same keyword saturation levels. But alas…they don’t.

All Keyphrases Aren’t Created Equal

Think about the competitiveness of the various keyphrases on the Internet. You have some like “search engine marketing” that are exceptionally competitive. Then there are others like “sushi
restaurant in Charlotte, NC” that aren’t. You have to take into account how many other sites you’ll be battling with when you write search engine copy.

Positioning of Keyphrases

In addition to the number of times a keyphrase is used, you need to pay attention to *where* your keyphrases are used. While it has not been proven to my knowledge, it is strongly suspected that keyphrases that have special formatting carry additional weight. By special
formatting I mean bold, italics, in bulleted lists, in tags, etc.

As I said, this has not been proven. Again, go to your favorite search engine and type in a keyphrase. If formatting and positioning were a carved-in-stone rule, all the sites in the top 10 would be using these tactics. But alas… they aren’t.

Why the Myths?

I understand why people want formulas. Having hard-and-fast rules to follow means that if you apply the formula, you know you’ve done the job right and you can’t fail. The problem is there isn’t just one right way to create search engine copy. There are as many ways to write SEO copy as there are sites on the Web.

Am I holding back? Am I trying to protect my highly classified industry copywriting secrets? Not at all. In fact, go to my copywriting site, visit the portfolio section. If I had a fiercely protected secret that I was holding out on, all the sites with SEO copy in my portfolio would have the same keyword density. But alas…they don’t.

What DOES Work?

So after I’ve dashed your dreams, the least I can do is give you some insight into how I write SEO copy. I don’t do any or all of these in any particular order. I don’t do them all every time I write. I am NOT saying that you should do all of these things every time you write.

1) If possible, I try to include keyphrase(s) in the headline and sub-headlines. If it doesn’t make sense, if it sounds odd, I don’t include them.

2) When it flows, I include keyphrases roughly once or twice per paragraph. Do I count words? Do I run keyword density ratios? Never! I just eyeball the page to see if it looks right.

3) This I do EVERY time I write… I focus on natural language. If the copy sounds forced after including keyphrases, I scrap it and start over. Read your copy out loud.

If it sounds stupid or redundant to you, it will sound stupid and redundant to your site visitor. Don’t compromise the flow of natural language for the sake of search engines. What good will #1 rankings do if as soon as visitors get to your home page they click away because the copy is so awful? All the #1 spots in the world won’t pay your grocery bill. You ultimately have to have sales and that means winning over your human visitors.

4) If possible, I try to include keyphrase(s) in bold, italic, bulleted lists, or in other text that is specially formatted. If it doesn’t make sense, if it looks funny or sounds odd, I don’t include
them.

So that’s it. Do you feel like you did when you were a kid and learned there wasn’t a Santa Claus or an Easter Bunny? Sorry. I truly am. But it’s for your own good. If you’re going to be an
effective search engine copywriter, you have to learn the truth. Relying on myths will only hold you back. Now pick yourself up, dust yourself off, and get moving on that next #1-ranking page.
