PROJECT SUMMARY – Technical SEO Fixes for Osclass Classifieds Website My classifieds site runs on the Osclass platform, and its technical health is now limiting organic growth. Multiple issues across crawlability, indexing, architecture and performance require a specialist who can work directly inside Osclass templates, core files, and server configuration. The priorities are clear: • Improve the overall site architecture so Google and Bing can reliably reach and index every important page without wasting crawl budget on duplicates, filter URLs or technical pages. • Increase crawl efficiency by fixing redirect chains, resolving canonical/noindex conflicts, tightening robots.txt rules, and generating a clean, valid XML sitemap index with properly structured gzip sitemaps. • Raise page-speed and Core Web Vitals, addressing server response time, CSS/JS minification, jQuery cleanup, caching, lazy loading, preloading critical assets, and modern image formats. Search Console already reports issues such as: faulty redirects conflicting canonical vs. noindex behaviour duplicate or parameter-based URLs being indexed poor metadata and heading hierarchy slow performance metrics and layout shifts Because of that, the job starts with a focused technical audit, not general surface-level optimisation. Deliverables I Expect 1. Technical Audit (Clear, Actionable, Concise) Identify: every structural issue with URLs, pagination, categories, locations and listing pages canonical tag errors and search/filter duplication sitemap/robots inconsistencies broken redirects, chains, loops metadata/title/H1 issues JavaScript/CSS performance problems Core Web Vitals blockers Schema markup gaps Each item must include: problem → root cause → recommended fix. 2. Implementation of Fixes Direct updates to: Osclass theme templates (PHP + HTML) core files if required (responsibly, with backups) .htaccess / Nginx config for redirects and canonical enforcement robots.txt and XML sitemap index + gzip sitemaps minified and combined CSS/JS, jQuery updates, removal of duplicates structured data (JSON-LD) for listings, categories and breadcrumbs image optimisations (lazy loading, WebP/AVIF, correct alt tags) filter URL handling (noindex,follow + proper canonicals) clean URL structure for locations and listings mobile UX improvements (e.g. sticky post-ad button) 3. Post-Implementation Report Confirm: all redirects resolve correctly (no chains/loops) sitemap index is valid and Search Console accepts it robots.txt is clean and does not block needed pages duplicate and soft-404 URLs removed or redirected canonical tags are consistent and aligned with SEO best practice metadata and heading hierarchy fixed site-wide Core Web Vitals improved (LCP, CLS, TBT) category, location and listing pages are index-ready filter URLs no longer appear in index schema markup validates successfully Required Skills You must be comfortable with: Osclass (PHP-based) architecture modifying theme templates and search/category/item pages Apache/Nginx redirects & rewrite logic Core Web Vitals Screaming Frog, PageSpeed Insights, Google Search Console structured data, canonical logic, sitemap design This is a focused, high-impact assignment—not just “install an SEO plugin.” If you can stabilise Osclass SEO foundations and eliminate structural issues, we can also discuss an ongoing optimisation phase afterward.
