I added the parameters to google web masters setting page:
sid : ignor for : .../adm/index.php?sid=bfc27a10ea61e8e60c4ac85f927a2d20
search_id :ignor for .../search.php?search_id=active_topics
i= : ignor for ..../ucp.php?i=676 and /mcp.php?i=646
mode : ignor for .../memberlist.php?mode and .../thankslist.php?mode=givens&author_id=59&give=false(thankslist mod)
st= : ignor for .../search.php?st=7&sk=t&sd=d&sr=topics&search_id=active_topics&start=6840
sg= : ignor for .../viewonline.php?sg=1
and i put here:
phpbb seo=> Extended Config=> _GET filter: "style,hilit,sid,ref,sid,i=,st,sg,search_id,mode"
is it true or false?
I think these parameters are better than the robots.txt
and what else can be added?
What do you think about it is wrong?
Thank you all
