Hey,i just wanna know Is rebsubmitting the sitemap in google account is necessary whenever my sitemap is updated or google crawls it automatically? coz whenever i resubmit after updating the url's n my sitemap it takes almost 2 hours to download & if i dont submit i don't know how much time it will take. coz the problem is there is huge competition in my niche although i provide the unique and fastest content but goolgle is not recognising me Google gives all his ranking to my competitors. can anyone suggest me what to do whenever i update my site.
I have not submitted a site map, yet when i post a new post to my blog it is indexed within 4 hours sometimes quicker. Are they really necessary ?
For me there's nothing wrong if you resubmit your site map but I think Google will indexed your site even w/o submitting it to major SE.
No i think you dont need to resubmit your sitemap every time you have update it. Insted of it give a link from your home page to your site map.When ever you update your site google will detect and update. I think it is not necessary to update site map every time. Dont you use Google web master tools?????
i never submit the sitemaps - just use social bookmarks for a couple of weeks and then when G starts visiting my blog regularly i stop using the social sites .
Its better to resubmit sitemap but if you provide link from your home page then it automatically get cached by Google.
