What's with measuring search rank?
-
Okay, here 6 different ways to measure search rank on Google U.S. and I get 6 different answers:
Looking for search term "Lunch Bags" for the site Zappos (just a random example - no connection to me).
SEOMOZ RankTracker - #49
SEOCentro - #36
http://www.seocentro.com/tools/search-engines/keyword-position.html
ZendProxy.com - #21
(an anonymizer proxy)
anonymouse.org - no rank
(another anonymizer)
Mikes Marketing Tools - no rank
http://www.mikes-marketing-tools.com/ranking-reports/
RankingCheck.com - #38
Can you duplicate a similar variation?
What gives?
Which if any of these would you rely on?
Thanks... Darcy

Hi Darcy,
I'm going through a process at the moment of a very thorough analysis of every tool I can get my hands on - more from a technical perspective because I was getting sick of the varying results from different tools / utilities.
I wrote my own scraper utility to get live results from Google as well. I tested 800 keywords using broad, phrase, exact, etc and the results from Google compared to every tool out there is different.
I'm currently writing a document on all of this. Maybe I should post it somewhere, I don't know, but my strong feelings at this point is:
-
check with each provider (of the online tool or downloadable software) whether they use broad match, phrase match, or exact match. SEM Rush displays results for "phrase match" but shows [exact match] search volume for that phrase. You almost need a database to remember what criteria each tool uses to return results.
-
do they allow you to filter results by domain (google.com, google.com.au, etc)?
-
in addition to the above, do they allow you to filter results by only showing results for that country (eg, if you can select "Australia", do they search on google.com.au AND give you the choice to see results for only .com.au domains, or all results that google.com.au would offer up?)
-
How recent is their data? Everything costs money - whether it's in API units from Google, API units from a competing tool, or even time and money spent on writing their own scraping software. Free tools aren't going to update their databases every day. SEOMoz (who I've found to be quite accurate) updates their Keyword Analysis Tool database monthly. A lot can happen in 4 weeks. Getting this information can be tough. You need to email each vendor and get their answer - and then trust their answer.
-
Tough one... but how savvy is the developer of the tool? I've written my own tools and it's damn hard to get accurate data even from Google directly! There's so many variables. Poorly written software returns poor results. In writing my own stuff, different proxies would return different Google results, even different user agents (web browsers) would return different results. You need a thorough understanding of the technicalities behind obtaining data from or about Google.
There's a few considerations off the top of my head. As I say I'm still putting together my findings. I'm using this reply as an opportunity to hopefully spark a little discussion on this as I think many people have the same problem.
The immediate solution? Write your own software, or use a few tools and average the results. I'm quite the analyst so varying results do my head in. However at the same time, is your goal to get 100% accurate results, or get a good "feel" for the competitive landscape and move on? Sometimes I like to get things perfect, other times my client doesn't have the time to wait, and I'm not paid enough to be that anal!

Accurate Google Keyword Ranking for a domain
Hi Folks, SEO N00b here, in a new job so please go easy on me if i ask stupid questions. I'm looking for some clarification on Google Keyword rankings. I am looking for accurate Google Keywords rankings as when I log into Google Webmaster Tools I am given values like (6-10) for a ranking? When I used SEOMoz (Research Tools -> Keyword & Ranking -> Rank Tracker) it gives me an even less accurate range by simply saying >#50?Why is SEOMoz giving a completely useless metric? Why is its actual rank not shown? I know rankings are becoming less useful as a metric with Google moving toward personalized search but I still have reports to deliver to clients so the conversation of what metrics are going in the report is to be had another day. Right now I just want to get accurate rankings, from what I've found online Google Webmaster tools is recommended as the de-facto ranking tool but it doesn't provide accurate results so how can that be (yes I know it averages out the ranking but 6-10 is a range of values not a single value that represents an average) Dave

Why Are Moz Pro Ranking SOOOO Inaccurate?
I have a set of keywords for which I have been consistently ranking in the top 10 for months. Moz Pro, a service that I pay for, has shown for the past couple of months that I don't even rank in the top 50. Google Webmaster Tools confirms that I have been ranking in the top 10 for these keywords. Am I doing something wrong or is Moz Pro more of an estimation tool? Thanks 😉

Couple of Moz's bugs
There are still some bugs in a new Moz: I can still find a lot of mentions of "SEOMoz", for example: in a footer, in a Q/A form (SEOMoz Resources), in a new question form (SEOmoz PRO Application, SEOmoz Tools, etc.) On a main form (http://moz.com/pro/home) sometimes my full name is not visible at all, sometimes my MozPoints are hidden (on a left top corner); There is not direct link from http://devblog.moz.com/ to a main website; Regards.

Why does SEO Moz say we are ranked lower than appears on Google Searches?
We are currently ranked 18th for the Sydney Vet keyword in SEO Moz ranking tools, however in organic Google search we are ranked third. This search was conducted without Googles personalised results feature. Is this just an error? Or does it have something to do with Google Places not being counted in SEO Moz ranking tools? Any help would be much appreciated.

Rank Tracker Logging Me #Out
Hi I was wondering if someone could help me with something? Whenever I try and use the rank tracker SEOmoz logs me out and won't let me log back in until I go to a different page. Is this because I am on a free trial (which I don't understand as I am able to use the other tools)

Exporting ranking stats; errors
previously, when I went to export the weekly rank stats, the csv opened into excel and everything was fine. This week, one campaign data will not export other than purely in comma deliniated and will not translate to colums in ecel. A second campaign does export directly to excel but the data showing (on 27th June) is for the 22 february (report created march 1). so all my spread sheets for position analysis are up the creek and I cant even get last weeks positional report on my key domain. any thoughts??
