Technical
1AMP
Invalid AMP pages won't be served by Google. Fix validation errors or remove AMP.
Technical
9Canonicals
Include a canonical link in your HTML to improve link and ranking signals for content.
Technical
9Content
Add more content to improve SEO relevance and user experience.
Technical
6Performance
Google treats LCP over 4 seconds as poor. The usual causes are an oversized hero image, render-blocking CSS, or a slow server response.
Technical
2External links
Investigate if too many external links might dilute SEO or hamper user focus.
Technical
3Heading length
The recommended H1 length is from 20 to 70 characters
Technical
9Headings
Every page should have one H1 tag for proper SEO structure and user clarity.
Technical
1Hreflang
Hreflang tags must be reciprocal. Each page must link back to all alternates.
Technical
9Images
Optimize image sizes to be under 100KB to improve load times and SEO.
Technical
1Indexability
Confirm if noindex is intentional; remove if you want this page to rank.
Technical
2Page size
Excessively large pages can slow load times and frustrate users. Optimize media & code.
Technical
1Legacy SEO
Meta keywords are obsolete and ignored by search engines. Remove to reduce page size.
Technical
3Internal links
Anchor text tells search engines what the linked page is about. Image-only or empty links pass the link but none of the context.
Technical
5Meta descriptions
The recommended length is from 70 to 320 characters
Technical
1Other crawl findings
Pagination loops can trap crawlers. Fix rel=prev/next implementation.
Technical
5Mobile
Without a viewport meta tag phones render the page at desktop width and scale it down, so text is unreadable without pinching. Google treats this as a mobile usability failure.
Technical
9Pagination
The first page of a paginated series should not have rel="prev" tags.
Technical
1Readability
Simplify language to improve user experience & accessibility.
Technical
1Redirects
Redirect chains slow page loads and dilute link equity. Update to direct redirects.
Technical
3Robots
Create a robots.txt file to guide search engine crawlers and specify sitemap location.
Technical
13Security
Use SSL if you are interacting with sensitive user data.
Technical
3Site structure
Pages buried deep in site structure may be less discoverable; improve internal linking.
Technical
6Sitemaps
XML sitemaps should contain maximum 50,000 URLs. Split into multiple sitemaps.
Technical
14Status codes
Internal pages are not responding. Check server status and page availability.
Technical
1Structured data
Structured data tells search engines what this page is about in a form they can read directly, which is what a rich result is built from. Netrix can write it for a page whose business has a verified Google Business Profile, using the details already published there.
Technical
7Page titles
The recommended length of the header is from 30 to 60 characters
Technical
11URLs
Remove or replace non-ASCII characters for best SEO practices, or ensure they're properly encoded.
Technical
