I have implemented a very basic click tracking mechanism for my newsletter. I just prepare the letter with links including a parameter like ref=123 and then verey page of my site will process this parameter, storing the data etc...
I have noticed recently that for almost every click from one of my subscribers, I have a click just after with the exact same parameter (i.e. same subscriber id) but coming from a Google IP!
I guess this has something to do with the way Google crawls my site and probably also with AdSense but I'm not entirely clear on what exactly this is and how Google can do this...
Anyone who could shed some light on this for me, please?
Then, I'd like to know how I can avoid storing those "clicks" in my database : is there a specific parameter that I can check that will tell me that this is a Google thing and I can safely ignore it? Of course, if it could be a check on something else than the IP it would be great because there seem to be an all bunch of them and I would like to avoid having to maintain the list.
Thanks for your help.
Still, initial question remains : why would Google rescan the page after every click from my newsletter subs? I'm not updating my site this fast...
Thanks.
This will continue to happen as long as you have the URL structured in this way, and you have adsense on the page.
If you block the spider, then you'll get no adsense ads either so I would recommend it.
Edit: To try and be a little more helpful. You could have a landing page that then redirects to the actual page with adsense on, but without the tracking parameter. If you want to track each and every page this person visits, then you'd probably be better off setting a cookie on the landing page and using that to track their behaviour
