Why there is no even close correlation between MajesticSEO data and Open Site? Explorer?
-
I compared my site home page against my competitor homepage with Open Site Explorer and I found that according Open Site Explorer I have only 3 backlinks where in MajesticSEO I have more than 100 backlinks in 'Historic' data and more 90 in '30 days fresh data'.
Why there is no even close correlation between MajesticSEO data and Open Site Explorer?
How SEOMoz count backlinks?

What's so awesome about a fresh index when it thoroughly confuses the issue (includes dupes from weird sessionIDs/URL parameters, etc). If MajesticSEO isn't showing accurate link count numbers, I have no use for it.

We did a bunch of work on this a while back, so my stats are probably not up to date (I think around October of 2010). Basically, we compared Yahoo! Site Explorer numbers, Google numbers (via the crappy but somewhat proportional link: command), Exalead, SEOmoz, Majestic and Alexa.
Majestic was definitely odd and so was Alexa. Neither of those two mapped/correlated well to the quantities reported by the others. Thus, for example, if xyz.com has:
- 50 links according to Google
- 1,000 links according to Yahoo!
- 500 links according to SEOmoz (Linkscape/OSE)
And site abc.com has:
- 100 links according to Google
- 2,000 links according to Yahoo!
- 1,000 links according to SEOmoz (Linkscape/OSE)
The percentages of quantity will match up fairly well for these, but not for Majestic (e.g. they might show 5,000 links for xyz.com and 3,500 for site abc.com).
This is a bit odd, but we don't know exactly why. They crawl a ton more links than even what Google/Yahoo!/Bing reportedly do, which could be part of it, but my best guess is the canonicalization and freshness issues. Since MJ crawls the web all the time, and doesn't build "indices" every X time period (like Google/Yahoo!/Bing/Linkscape), but rather maintains a single consistent link index to which new sites/links are added, the data structures may be different.
Majestic also appears, at least to us, to do far less canonicalization, removal of unnecessary URL parameters, etc. Thus, if one site links from 50,000 pages due to weird session IDs in the URL, that might bias the crawl and link count, but standard canonicalization will normalize these.
I really don't mean to bash on a competitor - MJ's fresh index is awesome, their tools are good, and a ton of SEO folks find them useful, including myself. But, on the index matching and link count numbers, we definitely see this same weirdness that many other SEOs do.
Hope that helps!

Opensiteexplorer more or less takes a representative random sample of the available links. More prominent links have a tendency to be visible on opensiteexplorer rather than majestic seo. Also check out yahoo links.

Why would a newly created site, have ranked ahead of our site for keyword that we are optimized for?
This newly created site has a DA of 1 and PA of 1, no backlinks, no optimized urls, the keyword they ranked better than us on was listed a total of 6 times on the homepage. Our PA is 29 and DA is 18 for the page that ranks for this keyword. They really copied a few elements of our site but made sure to change a few things, but also list at the bottom of their site 5 keywords that are crucial to our niche industry but they're all linking to the same page. Any ideas? It's an SEO guy running the site, we've watched them toy with adwords trying to be number 1, but not liking the price, so they are here and there with it. Mainly I don't see why they'd rank better for this keyword, we our site have prolly 500% more content that's both of quality and relevance to our customers, in the form of Pdfs, infographics, help sections, and video. Very baffled here, any advice would rock!

Why do some sites perform great but show no data on the tool bar?
Hey everyone, Been a paid member for 3 days and this is my first time posting 🙂 I have a quick question about competitive analysis with the MozBar. I do not want to point out the exact website (unless that is something cool to do on this forum), but there is a site ranking for a single keyword in the local 7 pack in slot one, which is also slot one for the SERP entirely. When I go to look at the page in more detail, the MozBar is showing no DA, PA, anything at all, and the Open Site Explorer is showing no links internal or external. I know that the page has to have at least some of these elements populated in order to be ranking for a term this competitive, so why is the bar not showing anything? The bar works GREAT on other sites below this one. Thanks for any help!

Help! New site won't rank locally but should...
any help would be greatly appreciated... picked up a new client, a used car dealer in New Jersey. Have a VERY spammy site before, tons of keyword stuffing and lots of dupe content. also had a horrible design. (www.coopscars.com) We updated the design and the content, made it relevant and unique, fixed title tags, etc. Now he's not ranking for anything locally other than his business name. He's got a decent number of links, we've added relevant citations, his social signals are much stronger than they were... We do lots of SEO for car dealers, and we know that he should be ranking SOMEWHERE at this point - not saying he should be page 1, but he should at least be somewhere in the top 5... and yes, bing/yahoo are different, but he ranks over there... one page 1 for "used cars south river" - so why completely non-existant on Google? just as a test, he put up a free website at www.coopscars.net just last week - and it's already ranking for several local terms. I'm completely confused here - i'm not a noob, I know the tactics we've used on him work for other dealers. Thinking there's got to be something that's blocking him, especially since there aren't but maybe 15-20 car dealers to compete against locally and he still doesn't show up... thought i'd come over here and see if anyone has any ideas...

How can my site not ranked on easy keyword while it currently ranked 1 on difficult keyword??
The site in question is http://ikt.co.id The site is perfectly optimized (or even over optimized) for keyword "Bikin Website Murah" (in Indonesia it means "develop an affordable website") currently if you search on both google.co.id AND google.com, it ranked on #10 (on google.co.id) and it ranked on #7 (on google.com), and both term only return 1.3 million results I have A LOT OF pages that started with 'bikin website' , or 'website murah' ... there are a lot of them, and i have had a lot of backlinks on those pages too (have been manually building a lot of links, starting from creating a tutorial article and blog submission and many other way) .. the site has been perfectly optimized for that keyword For example we have http://ikt.co.id/blog-category/bikin-website-murah-promo-terbaru.html (for newest promotion) http://ikt.co.id/blog/bikin-website-seo-murah-discount-40-sampai-31-juli-2011.html (for discount 40% promo that lasted untill 31 juli 2011) AND YET, if you search on google.co.id for keyword "2000 likes facebook" , our lone page that i created when our facebook likes reached that amount, RANKED #1!! , and please let me tell you this term return 400 million results++ (on google.com this keyword ranked #19, on 500 million results++). And let me tell you it take that SINGLE page (which has absolutely 0 backlinks) 2 days to ranked #1 .... and her brother if you searched "1000 likes facebook" also show similar result (though not better then the sister) How ?!? and Why ?!? , i dont understand this at all.... my domain does not contain any keyword, they uses the same engine and yet that lone pages which have absolutely no backlink ranked so well on a very competitive keyword, while my Target Keyword ranked poorly.... And what is even more bizzare? "Bikin website murah" might not rank good, but "bikin website" ranked better x_x ... arghh i dont get it... why my site ranked poorly on easy keywords and ranked high on difficult keywords :(( .... Why I am not smiling because those easy keyword is actually my primary keywords 😞

IP Address Of Site
Hi there, really new to seo and loving being able to research everything on seo moz. I have a question about the ip address of my site: I use a company that sells templated real estate websites (I'm a realtor) and I'm noticing all of their websites show as having the same ip address. There are probably 100's of sites on their server targeting the same keywords as I am, would this affect my ranking at all? I'm just considering switching to a Wordpress site with a unique IP address, so I'm curious to find out how the seomoz members would answer this question. Cheers, Adrian
