    About the project I'm building a B2B platform for wig makers and hair professionals to manage custom service bookings — think Acuity or Calendly, but purpose-built for services that need detailed specs, not just a time slot. Product name to be shared directly with the developer I move forward with. The platform has two connected parts: 1. Client-facing booking widget A multi-step form embedded on a wig maker's own website (Shopify, Squarespace, etc.) where their customers book services, select add-ons, and submit detailed specifications plus reference images. I already have a working HTML version of this built (7-step form with dynamic pricing, EmailJS integration) — it needs to be made fully embeddable anywhere and connected to a proper backend. 2.

    I’m looking for someone who can quickly diagnose why 324 of my blog-type pages still sit in “Discovered – currently not indexed” limbo while only 68 URLs show up in Google. There have been no recent URL or structural changes, and a sitemap is already live and submitted through Search Console. I’m also not running any SEO plugins, so nothing should be blocking Google from my end—yet something clearly is. Your first task is to run a thorough crawl and spot whatever is preventing those pages from getting picked up ( rules, rogue noindex tags, canonical conflicts, crawl-budget issues, thin-content flags, or anything else you uncover). As soon as the root cause is identified, I’ll need you to implement or outline the exact fixes, resubmit the affected ...
