I heard that the sitemap for Google can not exceed 10 Mb and 50 kURLs. This is not enough for me. What shell I do to pass through this obstacle? Create sitemap for each category?
Just use Sitemap index files:
You can provide multiple Sitemap files, but each Sitemap file that you provide must have no more than 50,000 URLs and must be no larger than 10MB (10,485,760 bytes). If you would like, you may compress your Sitemap files using gzip to reduce your bandwidth requirement; however the sitemap file once uncompressed must be no larger than 10MB. If you want to list more than 50,000 URLs, you must create multiple Sitemap files.
If you do provide multiple Sitemaps, you should then list each Sitemap file in a Sitemap index file. Sitemap index files may not list more than 50,000 Sitemaps and must be no larger than 10MB (10,485,760 bytes) and can be compressed. You can have more than one Sitemap index file. The XML format of a Sitemap index file is very similar to the XML format of a Sitemap file.
The Sitemap index file must:
- Begin with an opening
<sitemapindex>tag and end with a closing
- Include a
<sitemap>entry for each Sitemap as a parent XML tag.
- Include a
<loc>child entry for each
- The optional
<lastmod>tag is also available for Sitemap index files.
Note: A Sitemap index file can only specify Sitemaps that are found on the same site as the Sitemap index file. For example, http://www.yoursite.com/sitemap_index.xml can include Sitemaps on http://www.yoursite.com but not on http://www.example.com or http://yourhost.yoursite.com. As with Sitemaps, your Sitemap index file must be UTF-8 encoded.
