Comprehensive Site Audit: Core Web Vitals, Meta Tags, Report

Your budget for contextual advertising is leaking, and organic growth is stalling? After scaling a catalog or migrating CMS, technical errors often surface: broken links, duplicate pages, unoptimized Core Web Vitals. Our SEO audit identifies and prioritizes these issues, saving up to 30% of your fix budget.

We've conducted audits for over 200 projects – from corporate portals to marketplaces with millions of products. A typical case: an online store with 50,000 items had 1,200 duplicated titles – after fixing them, CTR increased by 15%. The audit pays for itself through increased organic traffic within 3–6 months.

What Technical Issues Does an SEO Audit Uncover?

Site crawling is the first step. We crawl the site with a crawler (Screaming Frog, Sitebulb, or our own Python-based tool) and collect all URLs, checking status codes, duplicates, erroneous redirects, and orphan pages.

# Quick check via sitemap import requests from xml.etree import ElementTree resp = requests.get('https://mysite.ru/sitemap.xml') tree = ElementTree.fromstring(resp.content) ns = {'sm': 'http://www.sitemaps.org/schemas/sitemap/0.9'} urls = [loc.text for loc in tree.findall('.//sm:loc', ns)] print(f'URLs in sitemap: {len(urls)}') # Status code check errors = [] for url in urls[:200]: # first 200 for demo r = requests.head(url, allow_redirects=True, timeout=5) if r.status_code not in (200, 301, 302): errors.append({'url': url, 'status': r.status_code}) print(f'Erroneous URLs: {len(errors)}')

How to Configure robots.txt to Avoid Indexation Errors

1. Ensure sitemap is specified in robots.txt: Sitemap: https://mysite.ru/sitemap.xml.
2. Verify that admin and cgi-bin sections are blocked.
3. For AJAX sites, add Disallow: /ajax/ if not needed for search.
4. Use Allow: / after Disallow for partial allowance.

# Check robots.txt accessibility curl -s https://mysite.ru/robots.txt # Check indexation in Google # site:mysite.ru – how many pages in index # site:mysite.ru/admin – no blocked sections in index 

Sitemap should contain only 200-status pages, no noindex, and correct <lastmod>. Size up to 50,000 URLs or 50 MB per file.

Checking Meta Tags and Headings

On-page analysis includes checking title and meta description:

# Bulk title/description check from bs4 import BeautifulSoup issues = [] for url in urls: soup = BeautifulSoup(requests.get(url).text, 'html.parser') title = soup.find('title') desc = soup.find('meta', {'name': 'description'}) t_len = len(title.text) if title else 0 d_len = len(desc['content']) if desc and desc.get('content') else 0 if t_len == 0: issues.append((url, 'no_title')) elif t_len > 70: issues.append((url, f'title_too_long:{t_len}')) if d_len == 0: issues.append((url, 'no_description')) elif d_len > 160: issues.append((url, f'desc_too_long:{d_len}')) 

Norms: title 50–70 characters, description 120–160. Template descriptions cause duplication issues. Headings H1–H6: one H1 with the key query, H2–H3 structure content without skipping order. Content: we check for thin content (<300 words), duplicates from supplier feeds, pagination pages with rel="next"/"prev" or canonical to first page.

Internal Linking and Structured Data

Good internal link structure distributes page weight and helps crawlers. Issues:

• Orphan pages – pages with no inbound internal links (crawler won't find them)
• Click depth > 3 for important pages
• Broken internal links – links to deleted/redirected pages

-- For SQL-based CMS: find pages with no inbound links SELECT p.url FROM pages p LEFT JOIN internal_links il ON il.target_url = p.url WHERE il.id IS NULL AND p.status = 'published' 

Structured data: we validate schema.org using Google Rich Results Test. Supported types: Product, Article, BreadcrumbList, FAQPage, Review, LocalBusiness, Event.

What's Included in the Audit?

As a result, you receive:

• Full crawl data dump (CSV/Excel)
• Prioritized issue list with effort estimates and expected impact
• Documentation on technical fixes for developers (with root cause and solution)
• Engineer consultation on priority fixes
• Quality guarantee: if new issues are found after fixes, a follow-up mini-audit is free

How Core Web Vitals Affect Rankings

Google uses CrUX data (field data) for ranking. According to Google Search Central guidelines, LCP should be under 2.5 seconds. If your competitor's LCP < 2.5s and yours > 4s, this is a serious factor when everything else is equal. Checking Search Console shows URL percentages in Good/Needs improvement/Poor. In the audit, we provide specific causes: unoptimized images, heavy JavaScript, slow server response.
