Rapid Google Index 9,000 WordPress URLs

I run a WordPress site with roughly 30,000 location-based pages, but only about 1,500 are actually in Google’s index. The site already uses Rank Math for on-page optimisation, yet the “Request Indexing” button in Search Console (10 URLs per day) is far too slow for my needs.

I want a reliable way to push at least 9,000 of the remaining pages into Google’s index as quickly as the guidelines allow, without flirting with black-hat tactics or risking a manual penalty. Whether you prefer the Google Indexing API, Rank Math’s Instant Indexing module, smart sitemap batching, or a custom Python script, I’m open—just be clear on your approach and the timeframe.

Deliverables
• Submission of a minimum of 9,000 unique URLs to Google using a white-hat method that respects their policies.
• Search Console evidence that those URLs were crawled and show “Submitted and indexed” (or equivalent) within the agreed window.
• A short hand-off document so I can repeat or scale the process later.

I’m a sole trader, so please keep your proposal cost-effective; I’m happy to break the job into milestones (e.g., 3,000 URLs per milestone) and release payment as each batch is confirmed indexed. Let me know what access you’ll need and which tools you’ll use, and I’ll get you set up right away.
