Often when you see a company that has decided to start working on an on page SEO
program they tend to end up making a completely different mistake altogether from the one they are warned of. To be specific, they start to forget about the real human visitors that will eventually be coming to their website when they decide to start improving their webpages for the search engines as far as content and technical specs go. In short, they trade the desire for a human's interest for the desire for a bot's interest.
You'll often see the results of this terrible mistake in a few different ways. For instance, you might truly bother people with your writing because it just doesn't flow properly just so that you can fit in a keyword, or maybe you just won't be able to capture the interest of your web site's readers and visitors because you have too much repetitive content that lacks any real personalitity.
Don't make the mistake of allowing the tail to wag the dog. Earning yourself top search engine placement isn't going to matter even the tiniest little bit if you become incapable of converting your brand new visitors into more business for yourself and your company. Doing your on page SEO copywriting in a professional manner can be very hard to do for a great many people. In a perfect situation you'd be able to find a nice synergy between the keywords you've decided to try and rank for and the things that you need to say in order to get your visitors excited about your product or service. In the end, though, if you find yourself needing to pick between the two, be sure to do your visitors and your company a favor and choose to keep your web page's conversion power.
