Free Link Popularity Checker and backlink analysis tool
Thursday, January 06, 2011
Open Site Explorer is the tool you need to rank better in the search engines and compare your site against your competitors.Some of the functionality provided by open site explorer.
Domain and Page Authority scores are calculated : Domain Authority is the best prediction about how content would perform in search engine rankings on one site vs. another. Page Authority answers the same question for an individual page.
URL level mozRank and mozTrust are calculated :mozRank is global link popularity score.It is similar in premise to Google's original PageRank metric but is updated more frequently and offers greater precision. It is on a log scale and computed to be between 1 and 10. The average mozRank on what most people think of as the normal web is about 3.00.mozTrust is global link trust score,It is similar to mozRank but rather than taking measuring link value, it measure link trust.
Domain level mozRank and mozTrust are calculated :Domain mozRank is exactly like mozRank but it is calculated on the Domain level rather than the URL level.
Internal vs External Links : An internal link is a link from one root domain to the same root domain.An external link is a link from one root domain to an entirely different root domain.
Followed vs Nofollowed Links :Followed links are not marked and pass link juice (Ranking Power)
Nofollowed links are marked (with either rel="nofollow" or meta robots nofollow) and do not pass link juice (Ranking Power)
Anchor Text & AltText :Anchor Text & Alt Text are meta data that are important to both humans and search engines.Anchor text is the text that is visible when reading a link. This text is established in the HTML code for a link.Alt Text is the text that is displayed when an image can't be.Alt Text is established in the HTML code for an image.
301s, 302s, and Meta Refreshes :301s, 302s and meta refreshes are all ways of redirecting one URL to a different URL.
301 refers to the HTTP Status Code for this type of redirect. A 301 Redirect is a permanent redirect and passed between 90-99% of link juice (Ranking Power)
302 also refers to the HTTP Status Code for this type of redirect. A 302 Redirect is a temporary redirect and passes 0% of link juice (Ranking Power). This is bad for SEO.
Meta refreshes are a different type of redirect that is executed on the page level rather than the server level
Img Links:Image links are links that appear as images instead of text in HTML documents. These are common navigational elements on websites as buttons and global navigation.
They pass juice just like other links but don't necessarily include anchor text
Number of Links vs Number of Linking Root Domains:Number of links and number of linking root domains are similar but different metrics.
Number of links (# of links) includes the total amount of links from all websites. Two links from the same website would be included twice.
Number of linking root domains (# of linking root domains) includes only the number of unique root domains linking. Two links from the same website would only be counted as one linking root domain.

You certainly have put a lot of work into this post. I think the link checker sounds like a fairly or very useful tool for blogger's to get. Although at first read I thought I saw a price of $99. mthly and didn't think a large amount of bloggers would be able to afford that price. Then after really examining the piece I see it's a free tool. You have really made my head spin around with your great knowledge and info you give about html,backlinks,and mozrank however I hope you realize that a lot of bloggers don't really or have the knowledge of html ect. I know I really don't, although after reading your post I would like to learn more about all of this. Thanks so much for the info. and I might call on you for help. lol thanks jj

I agree $99 a month is a little over budget for most of us. But the free service is worth trying it will help you know where you are getting your links from and learn not to be wasting time commmenting on high ranking sites that pass no juice.

I have recently used this site and it is pretty good. The main downside is that it only lets you check three domains a day.
Another one like it that is worth checking out is Backlinkwatch. And there's also Domain Pop, which I think is very new. The free version gives you quite a lot of info also.
