Welcome to the Q&A Forum

GWMT only shows that there are 3 domains pointing to a site of mine. I'm looking under "Links to site". But this can't be true because the site is pretty old and I know there are hundreds of domains that point to this one. What would explain this discrepancy? And is there some other free tool that will show all the backlinks? I've used Opensite explorer but that tool isn't close to comprehensive as GWMT usually is (based on other sites I've analyzed)

I have more than 25 keywords ranked in the top 30 for various sites and some of these keywords were inputted a couple weeks ago. However, only one of them has shown a position change. Is there something wrong with the software? It says the next rankings update is April 7th. When was the last rank update?

Is there a way to find sites that linked to my site during a certain time period? Say in the past 2 weeks or from March 1-March 15th ?

I'm trying to understand this concept a little further. Say if I create a branded keyword, "dc widgets" I then start to add keywords such as "maker" "toy" and apply the branded keyword to it. Does this mean that they then become "maker dc widgets" and "toy dc widgets" ? What purpose does branded keywords offer?

I have a website which is showing different serp rankings. On one computer, he's on the first page, on another, he's second page and another person from outside our office sees him ranked differently. What would account for the inconsistency in rankings?

I have a campaign setup a couple weeks ago and noticed that only 1 page has been crawled. Is there something I need to do to get all pages crawled?

Should I be linking to the author's G+ profile or their Google Places for the rel author tag? It's my understanding that Google Plus profile is different from G Places and hence two different urls. If I'm linking to the profile page of the author and not their Google Places, does this have any negative impact in terms of SEO?

If I set up a website on a new domain and have the old domain 301 redirected to the new domain, do the links pointing to the old site impact the new site?

Is there a way to determine which pages of a website are not being indexed by the search engines? I know Google Webmasters has a sitemap area where it tells you how many urls have been submitted and how many are indexed out of those submitted. However, it doesn't necessarily show which urls aren't being indexed.
