is Session Id affect my google ranking? i have some problems with Session Id and some pages are cashed with Session Id after links. 2 days after i get back in some keywords ranking. is it because of Session Id ???
Usually session ids put overhead over crawlers so its better to remove them for crawlers. But in your case NO it could not be due to session ids because it takes more time to see difference whether +ve or -ve.
try to convert to querystring. SE will craw this. usually session ID will cause problem, i see this at my site 1-2 years back.
today my traffic get back -120 visitors for site1, -530 for site2. i think it is because of Session Id. is there any effective way to kill Session Id. i try 3 codes in .htaccess: code 1: <IfModule mod_php4.c> php_value session.use_only_cookies 1 php_value session.use_trans_sid 0 </IfModule> PHP: code 2: <IfModule mod_php4.c> php_value magic_quotes_gpc 0 php_value register_globals 0 php_value session.auto_start 0 php_value session.use_trans_sid 1 </IfModule> PHP: code 3: <IfModule mod_php4.c> php_value session.gc_maxlifetime "7776000" php_value session.save_path "sessions" php_value session.use_cookies "on" php_value session.use_only_cookies "on" php_value session.use_trans_sid "off" </IfModule> PHP: but the problem not resolved yet. my host didnot support php.ini files.
yes, but the problems in SEO, because there are difference between your-urls.com and your-urls.com/?PHPSESSID=75d5d32d62f133b96d35a80ceb61d6ad
session id using will make your site difficult to crawl by search engines. i suggest verybody to remove sessionid from their url
Session id's are great spider traps which is why they don't like to crawl them, if you insist on having dynamic url's at least use parameters that don't bear any resemblance to session id's or the use of id, cid, pid etc. best option is to mod re write the url if possible
