Why so few links in webmaster tools

[totalvac]

In Webmaster Tools it only shows one domain linking to our site totalvac.com, but we have lots of external links. Why is this?

Hey There,

Not sure what Moosa meant by "re installing GWT" but I wouldn't go that route.  I do agree with checking OSE, Majestic, Ahrefs and other sources to form a total link profile as no one crawler will give you that.  And Google's will always be limited (at least for now).

If it hasn't been too long since you picked up the links or set up GWT then I'd give this some time.  GWT is notoriously slow and incomplete as Google doesn't necessarily give you all the data.

But if it's been a while I'd start to check things like "301ing your www. version of the domain to the non-www", double check your robots.txt file to make sure Google can crawl everywhere the links are pointing.  Make sure the links you think you have aren't nofollowed or the pages they are on noindexed.  But frankly the above isn't very likely.

I'd need to know more to make a full diagnosis but hopefully that gets you started.  If nothing else go with Moosa's suggestion and compile 2-3 other link profiles.  Dont rely on GWT for that complete data anyway.

There are times when Google Webmaster Tool takes time to update the data but if it is more than 2 weeks that you are facing this problem then you probably should try to reinstall GWT so that the data can be recovered and any problem in updating the data can be resolved.

In the mean time if you are interested in check the backlink data try using Open Site Explorer or Majestic SEO and they will tell you how many unique domains are pointing back to your website.

Hope this helps!
