Content is basically includes what you see on the site: the text, 
graphics and even links to outside world. I would condemn using 
excessive graphics because they are not Search Engine Friendly plus 
users feel irritation when they get downloaded specially over a slow 
network.
Thousands of articles, books and forum entries detail how to make 
your site search engine friendly, but ultimately, one rule stands above 
the rest: Content is king. But I will say this rule is past now and I would like to say Unique, high-quality, unduplicated content is the king.
Superior the quality of your content, the higher the ranking you 
achieve, larger the traffic you gain and greater the popularity of your 
website. Search engines prefer good quality sites in their index and 
search results.
A relevant, fresh, and timely content is crucial to attracting and 
keeping visitors to your web pages. It will help you both draw traffic 
from search engines and create audience loyalty.

spin on a topic. How is your material or content unique? Is that 
uniqueness obvious and easy to find and to understand? Visitors want

but also all the linked pages should have useful and easy to understand 
content.
