you can do it using yahoo or google, but if you want to know exactly the sumber use yahoo.

write that in the search engine of yahoo.

linkdomain:yoursite.com

yahoo is better then google in this case....because yahoo index the backlinks quickly then google.

I use SearchStatus | Firefox SEO Toolbar Extension with my Firefox. Gives you instant access to Yahoo and Google backlink searches with a click-drag. Highly recommended.

Seo Spyglass is a powerful tool to check your backlinks or those of their competitors
In the free version can be checked up to 1000 backlinks

www.link-assistant.com/seo-spyglass/ (no aff link)

Use SEO Spyglass or ScrapeBox backlink checker module

I use yahoo site explore and seomoz's tools

a brilliant way to find backlink numbers is yahoo explorer cuz it is free and accurate.

I like LinkPopularity.com: The Free Link Popularity Service

Yahoo site explorer is the best tool .
Try it

You try for yourself inlineseo.com. That works well.

Use webmaster tools to check the exact number of backlinks

Hello ,
we have so many tools like:
1. Rely on Google Search
2. Google Webmaster Tools
3. Backlink Watch
4. Yahoo! Site Explorer

Yahoo site explorer is the best..

Site Explorer - Yahoo! Site Explorer I use this always.

Just go here[http://siteexplorer.search.yahoo.com/] for checking the number of backlinks of your site.

You also can find the links by searching "link: your domain" in Google.

also, no offense if you're retarded

Yahoo site explorer will only give you limited number of links and I remember reading somewhere they will be closing site explorer down. If you want to get a complete list of backlinks, i recommend majesticseo.com

majesticseo.com is cool, thanks, but we need register it for checking more details about the site we want, is it for free?

Backlinkwatch dot com will do!

All backlink checker tools are not that accurate. So don't rely on them too much. But there's nothing wrong in using them to see your number of backlinks. Anyway, I would like to suggest seocentro.com and submitexpress.com. You can find a backlink checker there.

most of those sites are just pulling data around, so I think yahoo explorer is your choice

As others have mentioned, Yahoo Site Explorer is the best solution to check backlinks for free. They even allow you to pull the data out of it easily, including the anchor texts of the links!

For paid solutions I'd recommend MajesticSEO as they seem to have the most up to date link information and don't restrict you to 1,000 links like YSE does.

Traffic Travis is the best

SEO quake tool is the best

you can try backlinkwatch.com, its really a great source of check backlinks

There are many sites for this purpose like back link checker and also software are available and you can also check it by writing link:yoursite domain in google.

before that i use backlinkwatch, iwebtool to check backlink of myself and backlink of competitor. Until i start using spyglass SEO. i can feel it totally awesome which they provide a complete track of competitor backlink base on keywords and have the website that they build backlink from. It you want to compete them, you need to build backlink that they build and build more than them. Then no doubt that you able to overtake them in PR.

Yahoo site Explorer is the best for to check number of backlinks

try to use Web Directory Guide - WhichDirectories? | Helping you find the best paid, free, bidding, and niche directories. you can see list of back of links of our competitor

You can use market samurai to find out how many backlinks your competition has and you can also install SEOQuake from Mozilla Firefox..... these two will give you a rounded idea of how many backlinks your rivals have, also you will find out in MS how many times they are using the keywords in their articles and so on..............

Market Samurai recently said that they weren't very sure about Yahoo's accuracy any more and they were switching their backlink gathering to Majestic.
For one of my sites, I've been doing all the backlinks myself, manually and regularly checking them against Mkt Sam/Majestic and SEOQuake/Yahoo(?).
The differences are substantial e.g today's results : MktSam 30 backlinks to index page and 39 to the domain :: SEOQ : 90 to index and 90 to the domain.
I know the number of links I have done manually and allowing for a few I may have picked up naturally, I would say that SEOQ is far nearer the real total unless I had about 75% of all my 'hand-crafted' back links deleted as spam!
By hand-crafted I mean an email address in a person's name, not an auto generated one, entering of date of birth and other personal details robots wouldn't do, signature with a 'wise' quotation as well as a link, some minimal bio text etc and a reasonably intelligent post, in a thread which isn't for newbies - if I have to make a post at all (definitely not 'Hi, great to be here...').
If 75% of my manual links were taken as being spam and Mkt Sam is right, how can you account for the much higher SEOQ numbers?
Also if you click on the number of links, SEOQ lists them for you, and I can recognise the majority of the names.

try SEO Spyglass or Yahoo site explorer. hope this two things can help you.

Maybe try SEO Tool : Check Backlinks For Google, Yahoo & MSN see if it works for you..

Yahoo site explorer gets the job done.

yahoo site explore is really the good tool for yahoo for checking backlinks

yahoo site explore go down

Since Yahoo Site Explorer is no more, one way of doing this is to use Google Webmaster Tools (but only for your site), the industry seems to be moving more towards a premium service to find out your competitors backlinks

I Use Software That Called Spy Glass.

Yea me i just use SEO QUAKE.It works just fine.

Previe

check this site for back links :
backlinkwatch.com

hey,
You should use Yahoo to check the number of bascklinks on your site.

^^ ahrefs.com provides better results but most of its features are paid one.
