Think of it like this - if you write a really good article, ignoring any desire to design keywords to "attract traffic", you are not missing the point. If someone reads your article and is impressed they'll buy from you, well they will think about it. If they read it and think "what a load of rubbish" they'll go away.
So if you write your article for the robots, well unless robots get wallets and jobs and bank accounts, who's gonna pay for you to carry on writing?
I once wrote an article about "double tongues" and how to write for robots and humans simultaneously but you need extra talent for that and I think if you're here asking questions about it that means you can't have that extra talent, otherwise you'd already know what to do.
Play it safe and forget that robots exist, for the duration of writing your piece. If it helps to keep you on track, send the press release copy to 100 offline agencies as well, just to remind yourself that writing is for reading not just downloading by a machine and ascribing pageranks, keyword matches and all that jazz.
besides, after 10 years of letting keyword-exploiters play games with our mechanisms, we the robot and search engine builders are moving toward models which will bury this so-called 'seo' approach forever. the recession means that 90% of the cash being handed over for surplus pointless unwarranted rubbish will disappear permanently, and the types of marketing which go hand in hand with that rubbish will also be massively hit.
In the old days, the last time there was any noah's ark type situation on the web, it was the destruction of predominant banner ads... they were all the rage but low conversion. They were blown out of the water by text ads. I'm not writing off the banner/graphic ad per se. But in terms of the majority of what the market WAS at the time, they were just excess surplus often ugly rubbish. All pre-flash of course.
Now, interestingly, text adverts have started to go much the same way that banners did in the first years of this decade... have a look at my fun joke i made about it
And, ideally, you'd use it (once!) as anchor text, pointing back to the page on your site you're using to collect search traffic for that word.
