    Backlink Analysis - C-Class Address Check

    Does anyone know of a C-class IP address backlink analysis tool? Ideally a free web based tool or platform agnostic. I've searched high and low and can't find one.

    I gather a c-class backlink analysis tool would be able to provide an indication of a website owner's controls over the backlinks to a site. I know it's not fool proof as you can buy hosting that gives you different c-class IP addresses, but it would make a nice due diligence tool addition.

    Can't you just collect IPs and grep them?

    You building a dd tool, Luke? That would be really useful, nobody's made one of them before.

    Have you heard of Majestic SEO? I know the owner from webmasterworld.

    It's unique in that it doesn't rely on Google or Yahoo backlink results, it does its own crawl. That's a big deal in itself. From what I remember it also has the ability to sort links by C-Class.

    It's a paid service but I'll add my weight to majesticseo. It's proven pretty useful in the past. I've got their search function installed in Firefox (which is free).

    Thanks 3Six, I'll check it out. I'm surprised none of the other SEO site like SEOmoz, have one.

    They don't have the resources to do independent crawling on this scale.

    SEO MOz do have a great backlink tool http://www.opensiteexplorer.org/ although it doesn't identify C Class IP links, but I don't think that Majestic does either?

    In any case I don't think that it's a big issue, I would have thought that the best way to identify the quality of IBLs, other than actually visiting the linking sites, is to see where in the SERP the page is ranking for the targeted keyword phrase. If Google has identified a dodgy link profile then it won't rank well anyway. Why check that 2000 IBLs are on C Class IPs if the page is no where to be found in the SERP, it's acedemic surely?

    Plus there's the issue that Google is a domain registrar but they don't actually register domains. The obvious conclusion is that they just wanted access to the database to keep track of domains changing hands and why would they want to do that if SEO benefits are automatically transfered with a domain? The implication is that it isn't automatic, some domains probably get reset or nerfed in some way. PLus you could buy a domain with X IBLs but then your on-site content might be different enough to nerf the SEO beneifts from the bought domain (less likely it's true).

    Dunno, I don't have much practical experience with domains changing hands, I'm in the lower end of the market where clients tend to stay on one or two domains consistently. However, I do have a client at the moemnt who's thinking about buying a competitior's domain off them (they just went into liquidation) so I'd like to know more about this.

    What with everflux, personalised SERPs, long Google cookies, constant SERP experiments at the Gorg etc., whether a site ranks for you in the SERPs at a particular point in time from a specific IP isn't really indicative of much.

    So you're saying that the best way to check that a domain has meaningful IBLs , before buying it, is to identify whether or not they're on a C class IP since it's too hard to establish the page's rankings? I don't think that's meaningful, I could have 5000 C class IBLs and they could all be being ignored by Google.

    Maybe the best way then is to identify traffic that's converting from keywords in your Analytics package and be able to link (no pun intended) those keywords back to specifically targeted IBLs. VERY time consuming.
