What ages and types of knowledge your audience? Ordinary people may still stick around a general site on gardening, but a professional botanist might make his nose at the same site. Similarly, people will be leaving the site filled with astronomy abstracts, but a well educated university graduate will find an interesting website.
Take your audience's emotional state into consideration when building your website. If a very irritated visitor to find a solution and came across your website, you will want to make sure you offer the solution right in front and sell or promote your product to him second. In this way, visitors will trust in you to offer solutions to the problem and are more likely to buy your product when you offer him after that.
When you design a layout for your website, you need to take into account the characteristics of your audience. Whether they were old or young? Are they looking for trends or those just looking for information served without any icing on the cake? For example, introducing new games, and interesting with simple text, to be frank on page black and white background will certainly make the prospect much. Make sure your design in accordance with the general theme of your site.
Try to sprinkle colloquial language in your website with caution where you see fit and you will create a sense that your audience is on the ground with you. This in turn build a trusting relationship between you and your audience, which will come in handy should you want to market products to your viewers.
