Common SEO Mistakes on Small Websites (and How to Fix Them)

Many developer portfolios, SaaS landing pages, and small business websites struggle to gain organic search traffic not because their product is bad, but because of foundational technical SEO oversights.

Fixing these basic issues early ensures that search engines can crawl, index, and rank your content reliably.

Here are six of the most common SEO mistakes on smaller websites and the practical fixes for each.

1. Missing or Broken Canonical URLs #

When a website is accessible via multiple URL variations (e.g., https://burnjet.com/tools and https://burnjet.com/tools/ or http://...), search engines may treat them as duplicate content.

The Fix: Add an explicit self-referencing canonical tag in your HTML head:

<link rel="canonical" href="https://burnjet.com/tools" />

2. Ineffective robots.txt or Accidental noindex Directives #

It is surprisingly common for developers to leave active after migrating from a staging environment to production.

The Fix:

• Verify your production /robots.txt file permits search bots:

User-agent: *
Allow: /
Sitemap: https://burnjet.com/sitemap.xml

• Generate valid robot directives using the Burnjet Robots.txt Generator.

3. Disorganized Heading Hierarchy #

Having multiple

tags per page or skipping levels (jumping from

directly to

) confuses search engine crawlers about the main topic structure of your document.

The Fix:

• Keep one single

  per page containing the core topic.

• Use

  for primary subheadings and

  for nested details.

4. Missing XML Sitemaps #

Search engine bots rely on sitemaps to discover newly published pages, update frequencies, and canonical URLs.

The Fix:

• Maintain an up-to-date sitemap.xml referencing all indexable routes.
• You can generate and validate sitemaps using the Burnjet XML Sitemap Generator.

5. Slow Page Speed & Unoptimized Media #

Heavy uncompressed PNGs and blocking third-party scripts degrade Core Web Vitals (LCP, CLS, INP), resulting in lower mobile search rankings.

The Fix:

• Convert images to modern WebP format.
• Use modern responsive image elements with explicit width and height attributes to eliminate layout shifts.
