Advertising is very important. To qualify for some free publicity, you need to build the site such as with a simple search on Google your site will appear in the top three results. Here comes the complication. Let's say your site is called www.pc-games.com ; when someone makes a search on google "games" or ,,pc'', your site must appear in first results.
Basically, to achieve these results, you must use the text wisely. Your site must contain as much as these words (keywords) "games", "pc" but also other words you select (keywords). This means that a searching for those keywords you have selected and used as much as possible for your website, Google (or another search engine) will respond by displaying the position of your site.
But you can not write these words and only hope will be the first in the list. Google and other search engines comply with carefully analyze of the Website content, and if it detects an anomaly, the website that will be penalized.
If all those things related to S.E.O. (Search Engine Optimization), you can find it difficult ,there are on internet many websites specializing in SEO. Most have friendly interfaces, very easy to use.
After you have passed the SEO's, is time to search the products you want to offer for sale. I will remain on the example of games for consoles and PC. You should start looking for games most wanted by the public. Once you've done a list of these products you should look for relevant content about them. Information on each product must be various and very detailed. At the beginning you need to have a huge list of products, but try to sell 20 to 30 and see how it goes.
Another issue is frequently update on the site. When the sales increase you must offer content. If the site remain unchanged for too long, the sales will start to decrease until the point where your website will become dull in terms of content.
People like to talk and socialize. If they provide an opportunity to leave comments on your products, means that their opinion counts for you, and that's a good thing. You can make comments on forums or even a blog.
More details about the content of the site, what pages you need for your site, what information you should provide and where. Find in step 3.
