Search engine optimization (SEO), is the ongoing practice of optimizing a website to help improve its rankings in the search engines. Several internal and external factors are involved which can help improve a site's listing within the search engines. The higher a site ranks within the search engines for a particular keyword, the more traffic they will receive.
Piggy back on the success of others. Create a presence on websites which are highly trafficked. This is beside the Facebooks, the Twitters, and the YouTubes. Figure out the relevant sites in your niche and get yourself linked in there. If you are a music producer, it’s Soundcloud. If you are a Joomla developer, it’s the JED. If you focus on WordPress, it’s the Plugins directory. Find the behemoth in your niche, and piggyback a ride on their success. It's also good to find a niche in your niche. Riding on somebody's success is a guaranteed way of increasing website traffic. Hence the reason people guest post. More on that later.
The first thing to investigate after a major dip in traffic is your website itself. Is it actually working? Is there a problem with the domain? Mechanically, is everything functioning as it should? If all that checks out, make sure the critical inbound links are still intact. If the majority of your traffic comes from inbound campaigns, ensure your inbound marketing platform is working properly. - Jeffrey Kamikow, Cross Audience
Web traffic is measured to see the popularity of websites and individual pages or sections within a site. This can be done by viewing the traffic statistics found in the web server log file, an automatically generated list of all the pages served. A hit is generated when any file is served. The page itself is considered a file, but images are also files, thus a page with 5 images could generate 6 hits (the 5 images and the page itself). A page view is generated when a visitor requests any page within the website – a visitor will always generate at least one page view (the main page) but could generate many more. Tracking applications external to the website can record traffic by inserting a small piece of HTML code in every page of the website.[2]
