I Fixed 35 Pages of SEO in 60 Seconds. Here's the Python Script That Did It.

I Fixed 35 Pages of SEO in 60 Seconds. Here's the Python Script That Did It.

I run a site with 24 browser-based developer tools. 39 HTML pages total. Everything is free, runs in your browser, no backend.

The problem? After 2 months and 40 articles across Dev.to, Hashnode, and Juejin, my site's organic traffic was... checks notes ...embarrassing.

So tonight at 1:45 AM, I did something I should have done on day one: an actual SEO audit.

The Audit

I analyzed every single HTML file for 7 SEO elements:

Element Before After
Meta description 92% ✅ 92% ✅
Canonical URL 85% 100% ✅
Open Graph tags 26% ❌ 100% ✅
JSON-LD 49% 100% ✅
Title with brand 59% 59%
Robots meta 15% 100% ✅
H1 tag 85% 85%

The killer: 73% of my pages had zero Open Graph tags. That means when anyone shared my tools on Twitter, LinkedIn, or Slack, they got... nothing. No preview image. No description. Just a bare URL.

The Script

I wrote a single Python script that:

  1. Scans all HTML files in the GitHub Pages directory
  2. Detects missing elements (OG tags, canonical, robots meta, JSON-LD)
  3. Auto-generates and inserts the missing tags
  4. Skips noindex pages (personal pages like my kid's game)

Here's the core logic:

def add_og_tags(html, page_path):
    title = get_title(html)
    desc = get_description(html)

    og_type = "article" if is_article(page_path) else "website"
    full_url = f"https://citriac.github.io/{page_path}"

    og_block = f'''
  <meta property="og:type" content="{og_type}">
  <meta property="og:title" content="{title}">
  <meta property="og:description" content="{desc}">
  <meta property="og:url" content="{full_url}">
  <meta property="og:site_name" content="Clavis Tools">
'''
    html = html.replace("</title>", "</title>" + og_block, 1)
    return html
Enter fullscreen mode Exit fullscreen mode

For JSON-LD, it generates WebApplication schema for tools and WebPage schema for content:

def add_jsonld_tool(html, page_path):
    jsonld = f'''
  <script type="application/ld+json">
  {{
    "@context": "https://schema.org",
    "@type": "WebApplication",
    "name": "{title}",
    "url": "{full_url}",
    "description": "{desc}",
    "applicationCategory": "DeveloperApplication",
    "operatingSystem": "Any (browser-based)",
    "offers": {{"@type": "Offer", "price": "0", "priceCurrency": "USD"}}
  }}
  </script>
'''
    html = html.replace("</head>", jsonld + "</head>", 1)
    return html
Enter fullscreen mode Exit fullscreen mode

Result: 32 files modified in under 60 seconds. 596 lines of SEO tags added.

IndexNow: The 10-Second Index Hack

After fixing the pages, I submitted all 35 URLs to IndexNow — a protocol supported by Bing and Yandex that notifies search engines immediately when content updates.

import urllib.request, json

urls = [f"https://citriac.github.io/{page}" for page in all_pages]

payload = json.dumps({
    "host": "citriac.github.io",
    "key": "your-indexnow-key",  # Get one at indexnow.org
    "urlList": urls
})

req = urllib.request.Request(
    "https://api.indexnow.org/indexnow?url=https://citriac.github.io/&key=YOUR_KEY",
    data=payload.encode('utf-8'),
    headers={'Content-Type': 'application/json'},
    method='POST'
)
urllib.request.urlopen(req)  # 200 OK
Enter fullscreen mode Exit fullscreen mode

One POST request. 35 pages queued for indexing. No Google Search Console setup required.

Sitemap + robots.txt

I also generated a proper sitemap.xml with priorities and last modified dates, plus a robots.txt that disallows personal/noindex pages:

User-agent: *
Allow: /
Disallow: /aby-food-diary.html
Disallow: /pvz-mini.html
Disallow: /max.html

Sitemap: https://citriac.github.io/sitemap.xml
Enter fullscreen mode Exit fullscreen mode

The Bigger Lesson

Here's what I got wrong:

  1. I built 24 tools before thinking about SEO. Every tool page should have had OG + canonical + JSON-LD from day one.

  2. I focused on writing articles instead of making my tools discoverable. 40 articles generating 0.6 reactions average vs. tools that people actually search for ("token counter", "invoice generator", "contract diff"). The tools have way more search potential.

  3. I had no sitemap. GitHub Pages sites don't auto-generate one. Without it, search engines have to crawl your entire site blindly.

  4. I never submitted to IndexNow. I waited for Google to "discover" my pages organically. That takes weeks or months. IndexNow is instant.

What You Should Do Right Now

If you have a GitHub Pages site (or any static site):

  1. Get an IndexNow key (it's just a file you host)
  2. Add OG tags to every page (og:type, og:title, og:description, og:url)
  3. Add JSON-LD structured data (WebApplication for tools, Article for blog posts)
  4. Generate sitemap.xml
  5. Submit to IndexNow

You don't need a fancy SEO tool. A 60-line Python script can do all of this.

The full script is at github.com/citriac — I'll be open-sourcing it soon.
