Working with Olga was a really awesome experience. She has a unique ability to connect with developers and make them understand SEO.

There are 2 people in the industry I have learned the most from the last handful of years. Those two people are Olga Zarr and Nathan Gotch. She didn't charge me $99.99 to learn anything. Olga just posts super insightful YouTube videos and provides a insane amount of knowledge with her newsletter. It's one of the three industry newsletters I subscribe to to stay on top of whats happening because just like you, I rarely have time to stay on top of every announcement because I'm busy putting out fires and working with clients. Olga for President................... of Poland.

Common Technical SEO Issues And How To Fix Them

Below are detailed examples of common technical SEO issues I come across in my technical SEO audits and how to resolve them:

1. Core Web Vitals Passed in Lab but Not in Field

Field data reflects real-world user experiences, while lab data is simulated. If a site passes Core Web Vitals in the lab (e.g., Google Lighthouse) but fails in the field (e.g., Chrome User Experience Report), it may give a false sense of optimization.

Fix: Use Google Search Console Core Web Vitals Report to identify groups of pages with issues. Analyze individual pages in PageSpeed Insights and optimize problem metrics like Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). Focus on field data, as it’s what Google considers for rankings.

Technical SEO Audit Service - Core Web Vitals

2. Blocked Resources in Robots.txt

Disallowing resources like JavaScript, CSS, or images in robots.txt can prevent proper page rendering and indexing by search engines.

Fix: Remove disallowed directives for critical resources in the robots.txt file. Check robots.txt settings in your CMS or update the file via SFTP. Use Google’s URL Inspection Tool to ensure resources are crawlable.

Technical SEO Audit Service - Google Indexing

3. Incorrect XML Sitemap Entries

Sitemaps with invalid entries like noindex pages, non-canonical URLs, or error-prone links waste crawl budget and mislead search engines.

Fix: Ensure the sitemap only includes canonical, indexable URLs. Use tools like Screaming Frog to audit the sitemap. Adjust sitemap generation rules in your CMS or SEO plugins (e.g., Rank Math, Yoast).

4. Malformed or Conflicting Canonical URLs

Incorrect canonical tags can confuse search engines and dilute ranking signals. Common errors include pointing to URLs with errors, noindex tags, or redirects.

Fix: Audit canonical URLs using crawlers like Sitebulb or Screaming Frog. Update canonical tags to point to valid, canonical pages with a 200 status. Avoid conflicts between HTTP header canonicals and HTML tags.

SEO Audit Service Technical SEO - Canonicals

5. Conflicting Noindex and Nofollow Directives

Conflicting meta robots tags and HTTP headers can unintentionally block pages from indexing or passing link equity.

Fix: Ensure there’s only one directive (either in the HTML or HTTP header). Remove redundant noindex/nofollow tags and test changes with a crawler.

6. Disallowed or Nofollowed Internal Links

Internal links that are disallowed in robots.txt or nofollowed prevent search engines from accessing and ranking those pages.

Fix: Remove nofollow attributes from internal links unless absolutely necessary. Allow critical URLs in robots.txt. Use crawlers to identify affected links.

7. Low-Value Internal Links

Anchor texts like “Click here” or “Read more” offer no context to search engines and reduce the value of internal linking.

Fix: Replace generic anchor texts with descriptive, keyword-rich alternatives. For graphic links, ensure the alt text provides context.

8. Orphan Pages (No Internal Links)

Pages without incoming internal links are difficult for search engines to discover and index.

Fix: Add internal links to orphan pages from relevant, high-traffic pages. Use tools like Sitebulb to identify orphan pages and create a linking strategy.

Technical SEO Audit Service - Sitebulb

9. Faulty Redirects and Redirect Chains

Redirect loops or broken redirects confuse crawlers and harm crawl efficiency.

Fix: Replace faulty redirects with direct 301 redirects to the final destination URL. Use tools like Screaming Frog to detect and fix redirect chains and loops.

10. Links Pointing to Redirected URLs

Internal links pointing to redirected URLs create inefficiencies and waste crawl budget.

Fix: Update internal links to point directly to the final URL. Use a crawler to identify redirected links.

11. Invalid Hreflang Tags

Incorrect hreflang implementation can cause search engines to serve the wrong language or region-specific page.

Fix: Ensure hreflang annotations point to canonical URLs that return a 200 status. Include return tags and ensure all language/region codes are valid.

12. Invalid HTML in the Section

Placing invalid elements in the <head> can break metadata and confuse crawlers.

Fix: Audit the <head> section and remove invalid tags (e.g., <img> or <h1>). Ensure essential metadata like canonical tags and meta robots are intact.

Technical SEO Audit Service - Google Search Console

13. Technical Content Duplication

Parameter-based or case-sensitive URLs can create duplicate content issues, diluting rankings.

Fix: Use canonical tags to consolidate duplicates. Configure server rules to redirect case-sensitive or parameterized URLs to a single version.

14. Mixed Content and HTTP Links on HTTPS Sites

Mixed content (HTTP links or resources on HTTPS pages) can lead to browser warnings and undermine trust.

Fix: Replace all internal HTTP links with HTTPS versions. Redirect HTTP resources to HTTPS using 301 redirects.

15. Spammy or Irrelevant Pages in the Index

Hacked sites or incorrect configurations can lead to spammy URLs appearing in search results.

Fix: Use Google Search Console to identify and remove spammy pages. Secure your site against hacking attempts and regularly audit the indexed URLs.
