i have a huge sitemap for my site and it is becoming old. i want to resubmit the new map. does this affect the ranking??? thanks
It affects the amount of time Google takes to find the links thus affecting the amount of time your new links take too appear in the results so in a way yes It Does Affect Ranking.
Re-submitting a site map should not affect Google ranking as Google will be crawling your site pages for changes anyway. The site map is just a conventient way to inform Google of new pages, where as Google ranking is going to be based on the content of pages. Paul
For the most cases you don't need to resubmit sitemap. It's enough to notify Google that you've got sitemap in robots.txt and it will download it automatically before crawling your site.
Hi, If you have created a new pages in your website then it would be beneficial to resubmit your sitemap to google and other search engines to crawl your new pages and bring visitor's on your website new pages during website search process.
its not affect ranking but there is no need to submit again and again, instead of that u can keep build links.
I agree that you need to increase your links but you need to submit your Sitemap again and again when you will have new links. It may affect your ranking only if you will have a good content on your new pages. Anyway you may submit your Sitemap numerous times without any problem.
Resubmitting sitemap more frequently wouldn't hurt your rankings but it may help to rank well if you have authority URLS in the sitemap that are not seen by Google before. Every time Google indexes a new page it checks for Etag in the header for any modifications and then with the existing copy on Google servers, if the page is updated partially it updates the updated sections of that page. Before you resubmit the sitemap check how many pages are indexed on Google using site:yourdomain.com, is the # number of indexed pages is close to #number of URLs you have in the sitemap? Make sure you have unique URLs in your Sitemap, no duplication. If the # difference is significant check what are the URLs that are missing on Google and try to resubmit them, use the Canonical tag if you have some duplicate URLS already indexed on Google. <link rel="canonical" href="http://www.yourdomain.com/uniqueURL" /> And also think of how vibrant is your site? How frequently the site pages are updated? If you have a Google webmaster central account check crawler stats. Only submit those pages that are updated more frequently.
At one place - sitemap google bot find all links related to your website and that helps to regular crawling... if you have created some new pages then re submit sitemap.. or update your site map if any 404 page found remove that and re-submit... that will help your website to regular crawling by bot and if your website regular crawled than its truth it will help to get ranking.
