You MUST have high quality, unique content if you want long-term, free search engine traffic.

This is the most important tip of all. Sadly, it's one which many website
owners ignore.

Provide LOTS of information-rich, keyword-rich, useful content for the
search engines and humans to find.

You know that search engines are being clogged with junk at an alarming
rate. The other day, I came across a marketer who was boasting that he
owned more than 20,000 blogs - and he's not the only one.

Consider the scary effect of this exponential increase in low quality blogs
and websites. Old, large, well established sites will inevitably become more
and more important and trusted by the search engines.

Owning a large, well established, high quality site is a very solid investment
in your future.

These days, even Google's webmaster guidelines advise affiliates to
publish "unique and relevant" content.
If you spend time thinking of ways to provide truly USEFUL content that
people will talk about, you'll automatically end up with lots of free, one-way
links to your site as people recommend it without even being asked to do
so.

I've been building information-rich websites ever since I created my first site
in 1996. This method has worked extremely well for me and continues to
work very well.
If your website helps solve people's problems, they'll love you for it.
