My stats are getting fairly skewed for my relatively young site due to my working on it and checking things a few times daily.
Is there anything i can do, maybe a WP plugin, that stops analytics counting MY visits as I work on the site?
There is a plugin called Ultimate Google analytics plugin or something like that. If you use the plugin search feature in Wordpress and type "analytics" it will come up there. Install that and it will not show your own visits. It has a control panel for a number of basic or advanced options.
Yes. You can add an IP filter.
