How many links can we place in a single page of site map, suppose i have a heavy site consists of 2000 links, the main problem is weather can we place all 2000 links in a single page of the site map (or) can we split the half of links in a two site maps. if we place all 2000 links in single page of sitemap then can google crawlers will index all the 2000 links (or) they will miss few links? totally confused?
your views , suggestions, opinions are most welcome.
A sitemap file can include thousands of URLs and be several megabytes of data. Your 2000 links should have no issue. You can submit a sitemap in either txt or xml format. This will guarantee that search engines are aware of the pages.
It does not guarantee that search engines will add all of your pages to their index or rank the pages very high. That depends on how valuable the search engines feels your pages are.
I think you might be referring to html sitemaps that are intended to be used by humans. If you are creating a sitemap for your human visitors I would recommend to divide the links into smaller, more manageable pieces.
The original post seems to be asking about google sitemaps. Google sitemaps allows for a maximum of 10MB and a maximum of 50,000 URLs. If you do not want to upload a very large file for whatever reason, you can submit multiple, smaller sitemaps to Google.
Please remember that Google sitemaps are not intended for human use. It is intended to help googlebot to better crawl a website. https://www.google.com/webmasters/tools/docs/en/protocol.html#faq_sitemap_size
