The notion of off-page optimisation is one which has changed a lot over the past few years. Off-page optimisation has traditionally been focused toward a direct improvement in keyword ranking – predominantly through the use of link building schemes. But with the introduction of Penguin Google virtually put an end to the traditional form of off-page optimisation.
Since then, the purpose of off-page optimisation has evolved. Link building has been relegated and marketers are no longer relying on off-page optimisation for keyword ranking. Instead marketers are leaning towards an array of techniques to strengthen online reputation and increase web presence
List of off-page activities -
Also known as online reputation management, this is the first and foremost step with which you have to initiate your process. Try to become a member of the most popular social networking sites like Orkut, Myspace, Facebook, Linked In, Ecademy, etc., and create a profile of your own. By doing this you can extend your network online, get connect with your friends, share things with each other, and promote your company/website to build an online reputation. This is most likely the same as Web 2.0 (Participatory Web), which means you have to show your active participation on a regular basis.
This is one of the most powerful ways to promote your company/website online. Write a blog of your own for your company/website and include lots of unique content. Be precise in what you're trying to convey for the users in your blog entry and promote your blog in blog directories and blog search engines. You can also promote your blog/website by posting comments in other service-related blogs which allow links in the comments section that are crawlable by the search engines (these blogs are commonly identified as Do-Follow Blogs). If you're not very good at writing content for blog posts, hire a guest blogger for your blog and ask him/her to write precise and unique content so that your blog can gain more credit from a search engine point of view.
Create a forum/online discussion board of your own and start a discussion or share topics with your friends. You can also post/reply to a thread in other service-related pre-existing forums that allow links in your signature which can be crawled by the search engines (aka "Do-Follow Forums").
Submit your website to the most popular search engines like Google, Yahoo, MSN, Altavista, Alexa, Alltheweb, Lycos, Excite, etc., to get listed for free.
Many people may say that directory submission is dead. As far as I'm concerned it is still alive. It is purely based on how effectively we are selecting those directories and how efficiently we are choosing the category for submission. Of course, I agree that it gives quite delayed results, but it is worth doing it. Submit your websites to the topmost quality directories like DMOZ, Yahoo Directory, ZoomInfo, One Mission, Pegasus, etc. Nowadays many web directories may offer paid listings but don't go for it.
Social Bookmarking is yet another powerful way of promoting your website, but nowadays most people are spamming social bookmarking sites without knowing how to use them. Since content in these websites update frequently, search engines like these types of sites and often visit them (this is commonly termed as Tagsonomy & Folksonomy in Web 2.0). Do some social bookmarking in popular bookmarking sites like Digg, Delicious, StumbleUpon, Propeller, etc. You should be very careful while doing this and you must properly handle the tags which are very essential to broadcast your news on a wide area network. This may increase your website traffic based on how effectively you have participated.
Exchange links with service-related websites (this is commonly termed as Thematic Link Exchange) that can help increase your link popularity, which is a major factor of Google's PageRank algorithm. Beware of Black-Hats while doing exchanges.
