Are the stats for page impressions live or near live within 30 minutes or so? I have a pretty well visited site bur some days page impressions dont show up at all till mid morn uk, for example there are 3 page impressions showing for today, same about 4 hours ago- Yet more than that have registered as users never mind just browsed the search part of the site which the vast majority do.
I realise that I can't click on any of the ads myself which I have specifically refrained from doing, but I take it when visiting the site from my own ip adress the impressions would show up in the figures still? or are they disregarded.

Also I read on a post about not having 2 sets of ads on the same page I have 2 sky scraper ads one narrow one wide on left and right on one of the search pages,I thought they may be served with different ads, Can I be penalised/barred for this.

Any advice would be much appreciated.
