A Leading Digital Marketing Agency in India Studied Thousands of Sites and Found the Simple Errors That Quietly Hurt Search Rankings

MOHALI, India – July 16, 2026 – SEO Discovery, a digital marketing agency in India with over 22 years of experience, has released a new study after checking more than 50,000 websites across 20+ countries and 30+ industries. The goal was simple: find out what mistakes are stopping websites from ranking well in 2026, when people search not just on Google but through AI tools like ChatGPT and Gemini too.

The study found that most struggling websites made the same few mistakes, no matter their size or industry. These small errors led to slower search results, poor mobile performance, and almost no presence in generative search results, even when the website’s content was actually good.

The 5 Most Common Mistakes

This is what SEO Discovery found across the 50,000 websites:

  • No Schema Markup: About 40-50% of sites did not know that structured data was needed on web pages or, if it was implemented, did not implement it correctly. That was a barrier for search engines and also AI tools to understand the real idea of the page being delivered in full.
  • Slow Websites: A number of websites didn’t even clear the basic test for speed and performance, which led to lower search ranks, slow loading times, and shorter visit lengths that altogether had a negative effect on user engagement.
  • Copy-Paste Content: Repeated titles, descriptions, and near-duplicate pages were prevalent, particularly on online stores and websites with multiple locations, which further reduced the site’s topical authority.
  • Zero AI Visibility: Many websites were excluded from the results of the AI systems like Gemini, Perplexity, and even ChatGPT because they didn’t use AEO or LLM optimization, making it harder for AI systems to understand and cite their content.
  • Inaccurate Local Business Information: Wrong or old contact details and Google Business Profiles of the local businesses made them invisible/unreliable on online search platforms, resulting in less conversion.

Why the Findings Matter

The research was led by SEO Discovery’s in-house team of 400+ digital marketing professionals who track search changes every day. As the best digital marketing agency in India, the company built this study on real client data collected over 22+ years, not guesswork.

“Websites don’t lose rankings overnight. The decline happens gradually, as small issues go unaddressed,” said Mr. Mandeep Singh Chahal, CEO of SEO Discovery.

This study simply confirms what we already see in client audits every day. Fixing the fundamentals matters more than chasing new tactics. As a marketing agency in India working with clients around the world, the team compared results across healthcare, e-commerce, real estate, and tech businesses and found the same five mistakes almost everywhere.

Free Audits for Businesses

Based on this study, SEO Discovery is now offering a free website audit that checks for the same five issues: structured data, site speed, duplicate content, AI visibility, and local listing accuracy. Businesses that want ongoing help can start with SEO packages from $250 per month.

“We wanted to give business owners something simple and useful,” Mr. Chahal added. Even if you never work with us, knowing where your website stands is a good first step.

Interested businesses can request their free audit through the SEO Discovery website.
