Optimising a site with SEO alone is not enough. There are lots of things to be considered before anything gets done. In SEO for instance, doing onsite and offsite optimisations are just few of the things to be performed but there are still a lot more to do.
Updating your site with new contents is the best way of attracting search engines spiders to crawl onto your site. Search engine spiders always love fresh contents. Fresh text contents are their daily food and links are as their desserts. Links that you have generated out of link building such as social bookmarking sites submission, forum posting, blog commenting, blog posting, and others are not enough. Humans can’t live with desserts alone; they have to eat something that would gorge their stomach. Search engine spiders are like humans too. They need to eat. What they eat are the texts of the web pages. The more information is contained in a web page, the more likely that the search engines like your web pages. As a result, your site is visited more often, more like a favorite restaurant where these spiders can have a very satisfying meal.
Creating sitemap is also important. Aside from links and fresh contents for the site, sitemap is a factor in having your site crawled easily by search engine spiders. The spiders are enabled to crawl all the web pages of your site without missing a single web page. This is really ideal if you want all your web pages to get indexed among major search engines that SEO experts are targeting–the Google, Yahoo and MSN.
