So I just checked my AddThis account that I haven't look into for some time. I see some number of bookmarks. Most of them are in the way like:
example.com/page.html?variable=v1&gclid=whatever
"variable" is from my PPC campaigns and "gclid" is Google's thing.
Each of those URLs qualifies as a different one as GCLID is always a unique string (Google's click ID).
In order to fix duplicate content issue, I've been doing:
- 301 in .htaccess to erase GCLID (RewriteCond %{QUERY_STRING})
- I used Google's WMT and its "Parameter handling" feature to ignore those variables
Now I wonder how this affects the bookmarks that I see in AddThis?
Thanks
