Hello, I uploaded my site in G webmaster tool and for some keywords its showing position is 20 but I have not find me site even at 4th page and same thing with other KW . None coming in the exact position G webmaster tool telling me ?? is this inaccurate tool or any thing wrong ??? one thing more , What is meant by this expression " <1% " .
It's not an "issue"... it's a misinterpretation of what you're seeing... If you read what Google says about those positions, I'm pretty sure it's the HIGHEST position that one of your URLs ranked for that keyword phrase during the period of time the table is for. See http://www.google.com/support/webmasters/bin/answer.py?hl=en&answer=35252 and pay special attention where it explains "position": It's a little bit ambiguous in that it says "highest position" then it says "averaged of the last week". I'm not sure if this means 1) the highest position where it ranked at anytime during that week OR 2) that they look at the highest position you ranked for it each day of that week and then average the highs OR 3) if you have multiple URLs that rank for the same keyword that they take the highest for each of the URLs during that 1 week period and then average the highs for those URLs. Either way... you may rank around 500 normally and ONCE in a blue moon each day Google may through your URL on page one for shits and grins just to see how peeps react to it or because of various personalizations like geo targetting. And the number will appear abnormally high on this report. Regardless, NEVER rely on this page to see what your rankings are. You need to pull your own rankings for that. And the<1% means just that... "less than 1 %". So if it's in the top search queries column for "widgets <1%" then of ALL of the times your site's URLs were seen in the SERPs (say various URLs from your site were seen a total of 500 times total for ALL keywords in the last 7 days) then less than 1% of impressions (less than 5 of the 500 times) were seen when the user searched for "widgets".
