Creating an XML sitemap for a large B2B portal with approximately 500,000 pages requires an efficient approach. While WordPress does offer user-friendly plugins facilitating sitemap generation, transitioning such a substantial portal to WordPress might not be a straightforward option. However, for WordPress websites, various SEO plugins like Yoast SEO or All in One SEO Pack do indeed generate XML sitemaps seamlessly.
For non-WordPress portals, using specialized tools such as Screaming Frog, Ahrefs, or SEMrush could be beneficial. These tools often offer functionalities to crawl large websites and generate XML sitemaps. Additionally, Google Search Console provides options to submit sitemaps directly for indexing, regardless of the platform.
In the case of your non-WordPress B2B portal, utilizing these tools or platforms can efficiently generate XML sitemaps. Although converting to WordPress simplifies this process, leveraging dedicated tools or platforms remains the optimal solution for creating XML sitemaps for non-WordPress websites.
