How to fix SEO errors
Step-by-step fixes for every SEO rule Indxel checks. Critical errors first, then warnings. Code examples for Next.js.
Critical errors
— block CI buildsFix Missing Title Tag
Pages without a title tag are essentially invisible to search engines. Google may auto-generate one from your content, but it rarely matches your intent.
Fix Missing Meta Description
A missing meta description lets Google choose your search snippet. The auto-generated snippet rarely communicates your value proposition, reducing click-through rates.
Fix Missing OG Image
Links shared without an OG image get dramatically fewer clicks. A visual preview is the difference between a scroll-past and a click. Blank previews look broken.
Fix Missing Canonical URL
Duplicate content splits your ranking signals across multiple URLs. A canonical URL consolidates link equity to one definitive version. This is the highest-weight rule in Indxel for a reason.
Fix Missing H1 Heading
The H1 is the strongest on-page signal for your page's topic. Missing it forces search engines to guess your main topic from surrounding content.
Fix Broken Open Graph Tags
Social sharing is a major traffic source. Broken OG tags mean your shared links look unprofessional or broken, dramatically reducing clicks.
Improve SEO Score from F to A
A low SEO score means multiple issues across your site. Fixing them in priority order — critical rules first — gives you the fastest improvement.
Warnings
— reduce your scoreFix Title Tag Too Long
Truncated titles reduce click-through rates. A title of 70+ characters loses its ending in search results, often cutting off your brand name or key differentiator.
Fix Meta Description Too Long
Truncated descriptions lose their call-to-action or key benefit. A 200-character description that gets cut at 160 characters might end mid-sentence.
Fix Missing og:title
Social platforms display your HTML title including template suffixes like '| Brand'. A dedicated og:title lets you craft a title optimized for social context.
Fix Missing og:description
Social preview text is your pitch. When og:description is missing, platforms guess — and they guess wrong. Craft a social-specific description that drives clicks.
Fix Missing Structured Data
Pages without structured data miss out on rich results that dramatically increase visibility in SERPs. FAQ snippets can double your SERP real estate.
Fix Invalid Structured Data
Invalid JSON-LD is worse than no JSON-LD — you think you have structured data, but search engines ignore it. Silent failure.
Fix Duplicate Structured Data
Duplicate unique schema types create ambiguity. Google may ignore both blocks instead of picking one.
Fix Multiple H1 Headings
Multiple H1 tags confuse search engines about your page's primary topic. This is especially common in component-based frameworks where each component might render its own H1.
Fix Thin Content Warning
Thin content pages are less likely to rank and may drag down your site's overall quality signal. Google's Helpful Content update specifically targets sites with lots of thin pages.
Fix Accidental Noindex
A noindex tag completely removes your page from search results. This is the most dangerous accidental SEO error because it's invisible — the page loads fine, but Google ignores it.
Fix Missing Twitter Card
Links without Twitter card metadata show as plain URLs. Rich previews with images get significantly more engagement and clicks.
Fix Missing Viewport Meta
Google uses mobile-first indexing. Pages without a viewport meta tag are not mobile-friendly, which directly hurts rankings.
Fix Missing Favicon
No favicon = no visual identity in browser tabs, bookmarks, and search results. It signals a low-quality or unfinished site.
Fix Missing Image Alt Text
Images without alt text are inaccessible to visually impaired users and invisible to Google Image Search. This affects both accessibility compliance and SEO.
