SEO Audit — OG.gg

The situation

OG Esports (ogs.gg) is a well-known European esports organisation, but their website was showing signs of performance and SEO weaknesses that could be quietly costing them organic traffic. As a school assignment, I was tasked with auditing the site as if I were an external SEO consultant presenting findings to their team.

The audit covered three main areas: Core Web Vitals, page performance, and technical SEO structure — using real tools and real data from the live website.

What needed to be done

Three clear goals framed the audit:

• Evaluate the website's technical SEO health using Screaming Frog crawl data
• Analyse Core Web Vitals and Lighthouse performance scores (desktop and mobile)
• Identify the most impactful issues and prioritise actionable recommendations

My approach

I structured the audit in two layers: performance analysis (what slows the site down) and technical SEO analysis (what prevents Google from properly indexing and ranking the site).

For performance I ran Lighthouse tests on both desktop and mobile (simulated slow 4G), and cross-referenced the results with GTmetrix page weight data. For the SEO layer I used Screaming Frog to crawl the full site and check for metadata issues, broken links, and heading structure problems.

What I did

• Ran a full Screaming Frog crawl and identified 404 errors on key URLs (/news/, /?page_id=17)
• Measured Core Web Vitals from real user data: LCP at 2.9s (above Google's 2.5s threshold)
• Conducted a Lighthouse mobile test revealing FCP at 7.9s and TBT at 770ms — both hard fails
• Analysed page weight: 18.5MB total, with images alone accounting for ~75% (16.8MB)
• Documented 768KB of unused JavaScript and 14 long tasks blocking the main thread
• Flagged on-page SEO issues: missing/duplicate meta descriptions, inconsistent H1 usage, duplicate title tags, weak internal linking
• Identified UX issues: the 404 page gives no clear signal to users, and the homepage hero banner carries no CTA
• Delivered the findings as a structured visual presentation with priority-ranked recommendations

Key findings

The audit surfaced four critical problem areas with clear, actionable fixes:

Audit slides & data

The full audit was delivered as a 11-slide visual report, designed to mimic a real client-facing presentation.

What I took away

This project showed me how much invisible damage poor performance can do to a brand. OG's site looks polished visually but under the hood, a 62-second mobile LCP means a large part of their audience is leaving before the page even loads.

I also learned to distinguish between quick wins (converting images to WebP, adding meta descriptions) and deeper structural work (auditing JavaScript dependencies, fixing redirect chains). Prioritising recommendations by impact vs. effort is a skill in itself — just as important as finding the issues.
