A SEO health check is critical for ensuring your website ranks higher in search engines. Many sites have hidden issues that undermine search performance, even if their copy is high-quality. One common problem is non-functional URLs. These can be internal links that lead to 404 pages or outbound links that have been removed. Broken links negatively impact visitors and confuse search engine crawlers. To fix this, leverage SEO crawlers like DeepCrawl or Ahrefs to detect and resolve these links, or set up 301 redirects to guide users and bots correctly.

Another major concern is repeated content. This occurs when various versions have the nearly identical text, which confuses ranking algorithms over which version to prioritize. Common causes include dynamic filters, www vs non-www versions, and print variants. Best practices include using canonical tags, setting up 301 redirects, or preventing indexing of duplicates.

Poor load performance is another significant bottleneck. Pages that take more than three seconds drive users away and reduce visibility. To improve speed, optimize image files, remove whitespace from code, set long cache headers, 横浜市のSEO対策会社 and distribute assets globally. Also, upgrade your web host if your current one is underperforming.

Mobile-friendliness is non-negotiable since hundreds of millions of queries happen on mobile devices. A site must adjust fluidly to different screen sizes. Use Search Console’s mobile testing feature to analyze responsiveness. If problems are found, fix CSS layouts, ensure text is readable, and optimize interactive elements to click comfortably.

Incorrect robots directives or indexing meta tags can unintentionally prevent search engines from crawling key content. Review these files to ensure they’re not excluding high-value pages. Also, confirm sitemap freshness and submitted to search engines. A accurate sitemap helps crawlers efficiently index content.

Address format matters too. Unclean web addresses with unnecessary parameters are confusing to navigate. Human-readable addresses are recommended. Use 301 redirects to transition to cleaner versions.

Finally, ensure HTTPS compliance. If your site uses non-secure protocol, search engines may warn users. Enable HTTPS by installing an SSL certificate and redirecting all HTTP traffic to HTTPS. This boosts user confidence but is also a ranking factor.

Fixing these technical SEO issues may not seem glamorous, but they form the backbone for improved search performance and user experience. Regular audits help catch problems early and maintain peak performance.
