Extremely thin content. Google considers pages under 200 words as low quality. Add meaningful, valuable content.
Content should be broken into paragraphs using <p> tags. Wall-of-text content has high bounce rates.
Add internal links to your other pages. Internal linking is one of the most underused SEO techniques. It helps search engines crawl your site and distributes authority.
Linking to authoritative external sources can boost your credibility with search engines.
Very low text-to-HTML ratio. Your page has too much code relative to visible content. This can signal low quality to search engines.

Add an og:title meta tag. Without it, Facebook, WhatsApp, and LinkedIn will guess your title from the page content, often getting it wrong.
Add an og:description for better social previews. This controls the snippet text when your page is shared.
Add an og:image (1200x630px recommended). Shared links without an image get dramatically less engagement on every social platform.
Add an og:url to specify the canonical social URL. This prevents share counts from splitting across URL variations.
Add og:type (e.g. "website" or "article"). It helps social platforms categorise your content.
Add og:site_name to show your brand name alongside shared links.
Add <meta name="twitter:card" content="summary_large_image"> for rich previews on X/Twitter.
Add a twitter:title. Without it X/Twitter falls back to og:title, which may not be optimised for the platform.
Add a twitter:image. X/Twitter may not always use your og:image as fallback.
