Common SEO Mistakes to Avoid
Writing meta descriptions over 160 characters
Search engines truncate meta descriptions longer than 155–160 characters. Keep descriptions concise and include the primary keyword naturally within the first 120 characters.
Keyword stuffing in meta tags
Repeating keywords excessively in title or description tags looks unnatural and can trigger spam filters. Write for humans first — Google's algorithms are sophisticated enough to understand context.
Missing Open Graph tags
Without OG tags, social platforms pull random images and text when your page is shared. This results in poor previews that reduce click-through rates. Always set og:title, og:description, and og:image.
Blocking important pages in robots.txt
Accidentally blocking CSS, JavaScript, or key pages in robots.txt prevents search engines from rendering your site correctly. Always test your robots.txt before deploying.
Tips for Better SEO
Write unique titles for every page: Each page should have a distinct title tag under 60 characters that accurately reflects the page content and includes the primary keyword.
Target 1–2% keyword density: Use your primary keyword naturally throughout the content. Below 0.5% may be under-optimized; above 3% may look spammy to search engines.
Use OG images at 1200x630px: The recommended Open Graph image size displays correctly across Facebook, Twitter/X, LinkedIn, and most other platforms.
Submit sitemap after robots.txt: After setting up robots.txt, submit a sitemap.xml to Google Search Console and Bing Webmaster Tools to accelerate indexing.
