Yesterday, I received an email from someone who'd purchased one of my ebooks. Her question was
one I've been asked several times before: "How many instances of keywords within the copy are
enough?" That's like asking, "How long is a piece of string?" There isn't one answer.
Proponents of keyword density formulas will quickly spout out a percentage: 4%, 6%, 12%. However,
I wonder where they get these figures from. If you do a search in Google for any keyphrase (say
[cast iron frying pan], for example), you'll immediately see why keyword density formulas don't
add up. Either version - cast iron or cast-iron - bring the same listings on the search engine
results pages (SERPs). Please note: I was looking at the source code for each page so as to
include mentions in tags as well as on the page.
Cast Iron Frying Pan
Your results may be different than what I see, as everybody does not view results from the
same database. But, when I type in [cast iron frying pan] (no brackets, of course), the first
site that comes up is
http://whatscookingamerica.net/Information/CastIronPans.htm.
Total word count: about 1,611. Keyword density for [cast iron frying pan]: 0%. Keyword density
for [cast iron]: 3%. Keyword density for [frying pan]: < 1%.
Next up, Ask Yahoo: http://ask.yahoo.com/20000419.html.
Total word count: about 622. Keyword density for [cast iron frying pan]: < 1%. Keyword density for
[cast iron]: < 1%. Keyword density for [frying pan]: < 1%.
In the #3 position is Amazon.com at
http://www.amazon.com/Lodge-Logic-Pre-Seasoned-Cast-Iron-Skillet/dp/B00063RWUM.
Total word count: about 2,405. Keyword density for [cast iron frying pan]: < 1%. Keyword density
for [cast iron]: < 1%. Keyword density for [frying pan]: < 1%.
Mexico Cruise Vacation
Here's another example: [Mexico cruise vacation]. At #1 we see Cruise Web,
http://www.cruiseweb.com/MEXICO.HTM. Total
word count: about 488. Keyword density for [Mexico cruise vacation]: < 1%. Keyword density
for [Mexico cruise]: < 1%. Keyword density for [cruise vacation]: < 1%.
eCruises.com is up next with their page found at http://www.ecruises.com/.
Total word count: about 238. Keyword density for [Mexico cruise vacation]: < 1%. Keyword density for [Mexico
cruise]: < 1%. Keyword density for [cruise vacation]: 0%.
It goes on and on. Yes, you do find some sites that have really high keyword densities, but
it is not a given that attaining a certain across-the-board keyword density will guarantee
you good success. In fact, from what I've seen, keyword density has not been a valid measure
of SEO copywriting success in years. I believe it once was, but Google and other engines
quickly plugged the loophole.

Does Frequency Not Count At All?
Does that mean that engines don't give any consideration to how often keyphrases are used
within the copy? No. In fact, The Official Google Blog recently did a series entitled
Technologies
Behind Google Ranking.
In one of the posts, the author states, "The core technology in our ranking system comes
from the academic field of Information Retrieval (IR). The IR community has studied search
for almost 50 years. It uses statistical signals of word salience, like word frequency, to
rank pages." He continues with, "IR gave us a solid foundation, and we have built a tremendous
system on top using links, page structure, and many other such innovations."
Other Google documents make mention of the need to include key terms in your copy, so it is
established that keywords in copy can play an important role. However, I do not see evidence
that a standard, across-the-board "keyword density" is at play. Not to mention, forcing phrases
into your page text to the point that it sounds utterly stupid makes no sense. It's not going
to help your rankings (except maybe on some sub-engines), and it will almost certainly turn off
your site visitors.
So, back to the original question: "How many keyphrases are enough?" That's a
judgment call that comes with experience. Here are a few guidelines - not carved-in-stone
rules - but guidelines you can consider. And no, don't do them all every time.
Keyword Inclusion Guidelines
1) I make an effort to include keyphrase(s) in
the headlines and sub-heads if at all possible.
2) Adding keyphrases about once or twice per
paragraph is a good goal. I never count words or run keyword density percentages.
3) Focus on writing in natural language. Yes,
you want to incorporate keywords, but not to the point that you ruin your copy. It should
sound natural.
4) Read your copy out loud. If it sounds
stupid or redundant to you, it will sound stupid and redundant to your site visitor.
5) If it makes sense to do so, I try to include
keyphrase(s) in bold, italic, bulleted lists, or in other text that is specially formatted.
If you wouldn't bold or italicize the words or phrases to emphasize them to your visitors,
however, don't make a special exception for the engines. These are what I call Brownie point
tactics. The impact won't be significant, but every little bit helps.
Bottom line? Don't sacrifice the quality and conversion power of your copy to chase search
engine rabbits. In the end, it won't be worth it.
