Hi To All I am working as SEO in a Travel and Tour based concern website. I have Joined here this month only. The site which I am working right now is registered in 1999 and It has more than 1.5 lack Back links single Keyword is used as anchor text. Here nobody is there who knows about the site clearly.Because This site is completely developed from the outside source. So I couln't able to get clear information about the site. After my request only they have uploaded the Xml site map and I have registered in google webmaster tool. Now I found more than 600 pages are 404 not found. Web master warning. I t is completely php dynamic page. There is one option is also there to create URLs manually. The site page is changed several time and they are keeping old pages also in the server as different URL name. The site map contains two different more than two different URls for a single page. And it is redirected as 301 for the destination page. But URL which is redirected is also in the sitemap. Now I need some suitable suggestion from the experts. This is totaly new thing for me.
In a XML sitemap you cannot put URLs that are being 301 redirected and contain the URL it's being redirected to. Use either one or the other, for the sitemap just use the absolute URL and not the 301 redirected URL.
