90% of the websites we audit at NEXUS ÉLITE make at least three of these seven mistakes. Every day without fixing them is traffic you are giving to your competition.

Mistake 1: No keyword strategy

Many companies create content without researching what their audience searches for. Without keyword research, you are shooting blind. Tools like Ahrefs or SEMrush show you exactly what your potential clients search for.

Mistake 2: Slow load speed

Google penalises slow websites. If your page takes more than 3 seconds to load, you lose 53% of mobile visitors.

Mistake 3: Duplicate or thin content

Pages with little or copied content are a negative signal. Each page should have at least 300 words of unique content.

Mistake 4: Unoptimised meta descriptions

Your meta description is your free ad on Google. Include your keyword, a benefit and a CTA in under 160 characters.

Mistake 5: Incorrect heading structure

Multiple H1s or missing keywords in headings confuses Google. One H1 per page with the main keyword.

Mistake 6: No internal linking

Internal links distribute authority. Each article should link to at least 3-5 relevant internal pages.

Mistake 7: Ignoring technical SEO

Sitemap not submitted, misconfigured robots.txt, non-canonical URLs. A quarterly technical audit is essential.

How many mistakes does your website have?

At NEXUS ÉLITE we offer a strategic SEO audit under NDA analysing all 7 points with a prioritised correction roadmap.

About this article

This article was written by Gabriel Sandoval, Founder at NEXUS ÉLITE. Published on 12 Mar 2025 and updated to reflect the latest industry practices and data. Reading time: 6 min.

NEXUS ÉLITE is a boutique growth engineering consultancy based in Barcelona, Spain. We specialise in technical SEO, AI agents, custom SaaS development, business process automation, premium web design, influencer marketing and B2B and B2C digital campaigns. We work with companies with a validated product or service and genuine ambition to scale, regardless of current revenue.

All articles published on the Nexus Élite blog are written by our senior team of strategists, SEO specialists, AI engineers and copywriters. The content is based on real projects and verified data. We cite primary sources (McKinsey, Ahrefs, Gartner, HubSpot) where applicable. Our goal is to share the exact methodologies we use with our clients so that any company can apply them independently.

Our editorial process is rigorous: each article is reviewed by at least two senior specialists before publication, fact-checked against primary sources, and updated whenever industry data or best practices change significantly. We do not publish content for the sake of publishing — every article must answer a real question that real companies face when trying to grow their digital presence in Spain and Europe.
