According to Adil Raseed, articles published on high-authority sites like Medium, LinkedIn, and Google News-approved websites often get indexed almost instantly. Posting on your own website with a proper sitemap and using Google Search Console URL Inspection can also speed up indexing.

For instant indexing, you can post articles on platforms like Medium, LinkedIn, WordPress (with good sitemap submission), and Google Sites. These sites are frequently crawled by Google, so your content gets indexed quickly.

Articles usually get indexed fastest when published on high-authority platforms like Medium, LinkedIn, Quora, and Google’s Blogger, since these domains are regularly crawled by Google. However, for your own website, you can also use Google Search Console’s URL Inspection Tool to request instant indexing after publishing.
