What is a “Web 2.0”?

Web 2.0s are free blogging platforms. Most properties allow you to change URLs, images and video, contact forms, and a ton of other goodies. The web is composed of several different technologies and standards which work together to create a web browser, web server, web page, web application, etc. The web has many “generations” with the current version being web 2.0.

Web 2.0 can be described as a new age in web where people are using the Internet not just for reading but also for creating. Examples of this include social media sites such as Facebook and Twitter which have been rapidly growing in popularity over the past decade just to name a few. Web 2.0 sites allow users to contribute content on their own terms rather than just consuming content that others have created for them without an option of interacting or giving feedback back to the author of the article.

What Makes a Web 2.0 a Great backlink?

Web 2.0s are effective because you are piggy-backing off their authority and trust. Yes, it is a sub-domain and your page authority will start out with a goose egg ZERO. However, web 2.0 sites have quite a bit of link juice and by linking out to your web 2.0 pages from webpages, you give the web2.0 site authority that it gives back to you when your web 2.0 page is crawled by Google's bots.

A lot of webmasters get stuck on this concept and feel that they need a link from a high-authority webpage in order for their web2.0s to gain any traction with search engines other than Google, but typically all search engines take into account multiple links from many domains pointing at one URL when evaluating its ranking potential against authoritative pages throughout the web (including web 2.0).

Do web 2.0 links work?

The answer to this question is a bit complicated. If you build too many web 2.0 backlinks and you ignore the other types that should be a part of your link building strategy, it’s not going to work. The web is becoming more web 2.0 every day, with webmasters looking to increase their web-presence by using social networking sites, blogs, wikis and niche directories in order to build up web content that they hope search engines will take notice of.

While web pages are static, web2.0 pages introduce dynamic elements allowing webmasters to include data feeds from other websites or incorporate widgets containing code with popular social media plugins like the Facebook Like button or Twitter Tweet button (for example) which spiders like Google's can't follow little snippets of javascript when getting around your site. They provide a great way to syndicate your content or just pass juice to your site.

Tumblr is one of the better web 2.0 sites actually. there are even case studies to where people have ranked sites with nothing but Tumblr links.
