Building the Visitor Loyalty
Visitors who come to our website, will come again at another time, if in his heart said "the website is good for me" or "this website that I need". To attract visitors to come at another time there tips as follows from Mas Cosa Aranda:
* Provide content that is informative, up-to-date, quality and originality.* Provide something unique and not found on other sites.* Building interactions with visitors.
Content (content) quality
This is a key element of building a community-based web visitors. What if we sell the product Web site? Electronics stores for example? We can see examples of websites Innovative Electronics Surabaya. The website has not been optimized in SEO, including:
* Wesbite is based on frame, which complicate the spiders / crawlers.* The links in the menu using the pictures.* No ALT and TITLE attributes on links and images* All pages have the same title is the name of the store or company.
Although not optimized by SEO, judging from the traffic in Alexa, the current web ranking Innovative Electronics is not much different from tutorialgratis.wordpress.com this blog, so I expect my web visitors Innovative Electronics is the hundreds per day.Electronic Innovative Web also has a Pagerank = 4.
Pagerank (PR) is an important measure of whether or not a web page created by Google. The more other web pages that link to that page, the PageRank will be higher. Google combines a number of links and quality content to sort your web rankings in search engines. The lowest PR is 0 and the highest is 10.
