Resolve Google Indexing Errors

My site, londonlawtutor.com, is showing “Pages not indexed” warnings inside Google Search Console even though nothing significant has changed on the site for months. I need someone who truly understands on-site SEO and the inner workings of GSC to figure out why these pages are being skipped and to get them indexed quickly.

Here’s what I already know
• Error type: Pages not indexed
• Recent changes: None – no content edits, no redesign, no CMS switches
• Extra diagnostics run so far: none beyond Search Console itself

What I need from you
1. A clear diagnosis of the root cause (crawlability, canonical conflicts, robots.txt, sitemap, internal linking, rendering issues—whatever you find).
2. Practical fixes implemented on the site or documented for me if server access is required.
3. Submission and verification in Search Console so the affected pages actually appear in Google’s index.
4. A brief hand-off report outlining what was done and how to prevent the issue in future.

You’re free to bring in any tools you trust—Screaming Frog, Google Analytics, log-file analysis, schema validators—as long as the end result is clean index coverage. I can provide CMS and hosting access once we agree on an approach, and I’m happy to release milestones as each batch of pages is successfully indexed.

If you’ve solved similar “discovered – currently not indexed” or “crawled – not indexed” problems before, let’s talk.
