WordPress SEO Cleanup Needed

Do local seo and national My WordPress site is being held back by three concrete problems: a trail of broken links that throw 404s, sluggish page-load times, and a patch-work of missing or duplicate meta titles and descriptions. I’d like a specialist who can move quickly from audit to fix, leaving me with a site that loads fast, has zero crawl errors, and shows clean, unique metadata on every important URL.

Here’s what success looks like for me:
• All internal and external links verified and repaired, with no 404 errors showing in Search Console or Screaming Frog.
• PageSpeed Insights and GTmetrix scores comfortably in the green, achieved through smart caching, image optimisation, and any safe server-side tweaks you recommend.
• Complete scan of titles and meta descriptions, followed by creation or consolidation so that every page has unique, properly-sized tags.

Please work directly in WordPress—feel free to leverage tools such as Yoast/Rank Math, WP Rocket, or custom snippets if that’s faster—as long as the end result meets the criteria above and nothing breaks the theme or existing functionality. I’ll provide full admin access and expect a brief hand-off document summarising the changes made and remaining best-practice tips once the job is done.
