You've lost all traffic from Google?

Does your Google Webmaster Panel give any error messages?

Hi there Joe Ward
i lost 50% of google traffic for forum
in sitemap i have warnings in sitemap10
All the URLs in your Sitemap have the same priority.
All the URLs in your Sitemap are set to the same priority (not the default priority). Priority indicates the importance of a particular URL relative to other URLs on your site, and doesn't impact your site's performance in search results. If all URLs have the same priority, Google can't tell which are more important.

i dunno what to do with google really
what should i do to get back my traffic from google?

any help ???

Hello,

check this please: Google - Sitemap have the same priority

since many days i don't have errors in sitemap or warnings
but i dunno why google not showing my forum as before
when i was searching for some keywords of subforums, my forum was showing in first and second google page
now i lost about 30% of my google search traffic or more !!!!

what can i do?
i have sex keywords in footer but they are showing not hidden
but they are not relevant , i don't have sex content in my forum
do u think this is the reason?
i'm getting traffic from these keywords and scared if remove them i'll lose the traffic!

99% chance it's those links.

remove them.

paid links are a HUGE no-no.

i don't have paid links
what to remove .... remove the non relevant keywords?
i have sex keywords but don't have sex content in forum

Why would you have sex keywords on a site that does not have sex content? You say you do not want to loose traffic because you get a lot from the keyword sex, but once they figure out your site is not about sex they leave anyways. Best to remove all traces of it.

i removed the non relevant keywords,
i added this yesterday

HTML Code:

if($vbseo_stat['urls_no'] == 0)
            $priority = min($priority+0.0001, 1.0);

and in night after the warnings of site map went out,i search for some keywords and get my site back in search result
i check it today searched for the same keywords and didn't find my site

i went to webmaster tools and i notice that the error warnings back in sitemap 11 and sitemap 66

i really think now and sure that this warning is the reason
so how can i fix this??

i really dunno what to do in this, when i error went out after of 20 min of resubmitting google show my site for much keywords, i searched for these keywords now and i don';t see my site

this effect my business so much really
what should i do?

do u think its from forum keywords?
i have about 20 keywords + thread keywords!!!?

hello.....can ui help me in this plz?
this is really distroding my business!!!!!!!

You may have been penalized for something. You submit a re-inclusion request if you believe your site was unfairly penalized.
How do I request reconsideration of my site?

yeah but when i resubmit sitemap and no warnings i search for some keywords and find my threads
but when get the warning on sitemap again i don't find my threads!
so i believe that the warnings in sitemap effect also!!!
how can i solve this problem?
