These are the bes off-page seo tips.
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.
2- Forum Postings
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").
3- Search Engine Submission
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.
5- Social Bookmarking
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.
