Some of these might seem they have been drug out and beaten many times, but you still see sites employing these methods, scattered across the internet.

Do not stuff the same keyword / keyword phrase into every header tag!
You will not pass search engine spider inspection, and your website will appear dull and boring to actual readers who might actually have an interest in your site.

Do not cram your title with tons of keywords!
Your title should be quick and to the point, and optionally include your site name at the end. It’s there to inform both visitors AND spiders of exactly what the page is about.

Do not bold the same keyword over and over and over!
Using bold to emphasize points you are trying to make is great, and can help visually direct a user along your idea’s path of progression. However, if used and abused, it can quickly turn the same visitor away.

Do not stuff keywords into the alt attributes of your images!
This is another SEO No-No! Alt attributes should accurately describe the image that it is describing. Nothing more, nothing less. Make sense?

Do not stuff keywords into anything, period!
It’s easily picked up on by search engine spiders, as we’ve all learned one way or another, and it can just as easily repel potential readers or customers.
