Search engines also assess, in great detail, the technical aspects of your website. For example, how quickly the site loads plays a major role in your website ranking. Search engines also take into account how accessible your server is. Because, ultimately, Google and other search engines want to provide the best possible search results. So, the aim is to guide visitors to sites which work well, and which can always be accessed and used. Short URLs are more appealing to users in search results, are easier to remember and are simpler to type without making mistakes. Google says, that "in general" they do not follow nofollow links. That also means that they do follow the link sometimes if they think that the link is still important. The basic thing you need to remember when doing SEO is that you want to get as many links from as many high quality websites as possible. This can be a difficult thing since getting your links approved can take a lot of time. Search engine optimisation (SEO) refers to the efforts required to ensure your website is discoverable by search engines and in turn, your target customers. The better optimised your website is for search engines like Google, the greater chance you have of ranking for keywords or search queries that your customers are searching for. The main goal of SEO is to increase your search visibility and your organic (free) traffic.
