How to get backlinks quickly

Backlink is one very important thing in SEO. Here, I want to share with you the tips how to get backlinks quickly.
1. Using ‘Scraping’ to promote links.
This is more for bloggers than Hubpagers, but one thing I’ve found is that quite a few of my blog entries have been copied in their entirety (or scraped) – so rather than try and stop people from doing this and spending hours or days trying to force them to delete the content, I have found that if I can insert some links to my other pages, then I will at least get a benefit out of this copied content.
The one way to do this is to use a plugin designed by Yoast – it’s an RSS Footer plugin for wordpress – essentially install the plugin and add some links using this tool to your hubpages, blogs etc. Thus when someone ‘scrapes’ your content at least you’ll have some backlinks.
2. Join Forum / directory signature
Quite often I will be active in forums and directories even when I am not trying to promote a website – for example, today I did a lot of research trying to find out how to finish an installation of Windows 7 after encountering a ‘restart loop’ – I visited probably 50 websites and left relevant comments on each of them – where possible I include a link to a relevant site of mine. I do note that each of the links I place were relevant to the discussion – simply putting a link to XBOX Games in a Windows 7 forum isn’t going to get you much traffic and in many cases may well get you banned from the forum.
It is very important that you are an active member of the forums you post in - simply adding comments just to get backlinks is not acceptable and can often get a backlash to your site and indeed to Hubpages. The same goes for directories - simply spamming every directory with every hub is an overkill and probably will not help in SEO - the best thing to do is select some very good directories and then only post relevant and quality sites to these directories.
3. Facebook
This is my newest place to post links – I have joined quite a few groups on Facebook that interest me. I visit these groups and participate – occasionally someone will ask a question about something I have already written a web page and I’ll provide a link to my content – as I am known in the group and constantly participate in the group then I do get quite a lot of traffic this way. It’s part of my normal day routine to visit these groups so I’m not spending that much additional time getting back-links.
As I mentioned above, it is important that you don't overdo this and don't simply post every hub to every group you can find. Become an active member on some groups and then only post quality hubs that are relevant to the group or the discussion.
3. Digg
The use of sites like Digg, reddit and other bookmarking sites is often a good way to get people to visit your site and also creates an instant backlink - it is important that you are active on these sites otherwise your sites tend to get boycotted pretty quickly. Try and post your most unique sites on these bookmaring sites - if you can catch someone's eye with your site then you soon can find it becoming extremely popular.
Yet again it's important that you simply don't post your hub to these sites, but concentrate on being an active member on the site and posting hubs that are quality hubs and are actually going to be useful for others to read - simply posting a hub selling dongles isn't likely to get the Digg community excited.
4. Circle of Sites
When I design a site I actually create 1 main article and then several introduction articles. I post my main article on Hubpages and then spread the other articles over sites like Blogger, Shetoldme, Xomba, Redgage etc. Thus I am creating some quick backlinks before I even start to promote my site. I also find that as I begin to get followers on these other sites I do seem to be getting increased traffic on them.
