Digg

www.digg.com is a popular website that involves elements of social bookmarking and blogging. It places an emphasis on science and technology but has recently expanded to included categories such as politics and entertainment. The latest stories and websites are submitted by registered users and editorial control is democratic. This means that news stories and web site links are submitted by users and they are only moved to the front page of Digg based upon a user-controlled ranking system. This is how it works. Users can view all the stories or link that their fellow users submit. If a story gets enough ‘diggs’ it gets promoted to the front page of the Digg website. If it doesn’t get enough ‘diggs’ it remains in the ‘digg all’ area, where it will eventually be removed. A post may also be removed if enough users report a problem with the link.

All the content on the Digg website is free. Originally Digg carried fifteen categories in which to submit stories. These were deals, gaming, link, mods, robots, security, technology, design, Apple, Linux, music, hardware, movies, programming, software and science.

However, Digg was recently revamped and the previous categories have now been worked into the six new categories, which are: technology, science, world & business, sports, entertainment and gaming – with each category having subcategories.

On Digg, users can discover web content from just about anywhere. Whether it’s the biggest names on the web or the most obscure blog from the other side of the world, you will find it on Digg.

There are no editors on Digg. The editing is done by all the users together. The users together determine the value of the content that is available. All the content is user driven – from the blog posts to the pod casts.

Once you submit your post, it is instantly visible to all Digg users. If your submission is a good one and it gets enough Diggs, it gets promoted to the front page of the website. There it is available for viewing by millions of users around the world. Since Digg is all about sharing and making discoveries, users can also build conversations around the content that is posted. Digg provides users with tools to comment on and discuss topics they are passionate about. When you go through Digg, you will quickly realize the benefit of working through the lens of other users who have the same interests as you, simply because it acts as a content filter. This ensures that you only get the most interesting, relevant and unique information.

Link Spamming

Realizing the importance of links and link analysis in search engine results, several link farms and Free for All sites have appeared that offer to provide links to your site. This is also referred to as link spamming. Most search engines are smarter to this obvious tactic and know how to spot this. Such FFA sites, as they are known, do not provide link quality or link context, two factors that are important in link analysis. Thus the correct strategy is to avoid link spamming and not get carried away by what seems to be too simple a solution.

Tables

When you use tables on the key pages and if some columns have descriptions while others have numbers, it is possible that this may push your keywords down the page. Search engines break up the table and read them for the content the columns have. The first column is read first, then the next and so on. Thus if the first column had numbers, and the next one had useful descriptions, the positioning of these descriptions will suffer. The strategy is to avoid using such tables near the top of the key pages. Large sections of Java scripts also will have the same effect on the search engines. The HTML part will be pushed down. Thus again, place your long Javascripts lower down on key pages.

Avoid image maps without text or with links. Image maps should have alt text (as also required under the American Disabilities Act, for public websites) and the home page should not have images as links. Instead HTML links should be used. This is because search engines would not read image links and the linked pages may not get crawled.

Frames

There are some engines whose spiders won’t work with frames on your site. A web page that is built using frames is actually a combination of content from separate “pages” that have been blended into a single page through a ‘frameset’ instruction page. The frameset page does not have any content or links that would have promoted spidering. The frameset page could block the spider’s movement. The workaround is by placing a summary of the page content and relevant description in the frameset page and also by placing a link to the home page on it.
