Check that all meta descriptions are placed correctly within the <head> section of the HTML document.
Move any meta descriptions found outside the <head> tags to the appropriate location.

META KEYWORDS

1. Meta Keywords Missing

Meta keywords are no longer considered relevant for SEO by major search engines like Google. Therefore, the best practice is to remove them altogether from your website's meta tags. Here’s how you can fix the issue of missing meta keywords:

Remove Meta Keywords Tag: Open your website’s HTML code and locate the <meta name="keywords" content="..."> tag in the <head> section of each page. Delete or comment out this tag entirely
.Update CMS or Template: If you're using a content management system (CMS) like WordPress, Joomla, or Drupal, check if there’s an option to disable or remove meta keywords in the SEO settings or through a plugin/module

.

2. Duplicate Meta Keywords

Even though meta keywords are deprecated, if you still have them and they are duplicated across multiple pages, you should:

Review Each Page: Inspect the <meta name="keywords" content="..."> tag on each page to ensure that they are unique. Replace duplicated keywords with relevant content-specific keywords or remove them entirely
.Automate Removal: If your website has hundreds or thousands of pages, consider using find-and-replace tools or scripts to remove duplicate meta keywords across your site

.

3. Multiple Meta Keywords Tags

Having multiple <meta name="keywords" content="..."> tags on a single page is unnecessary and can confuse search engines. To fix this:

Consolidate Tags: Ensure each page has only one <meta name="keywords" content="..."> tag in the <head> section. Remove any additional instances of this tag
.Audit Your Code: Use developer tools or your CMS’s backend to search for instances of multiple meta keywords tags and remove the extras

.

H1

MISSING H1: Ensure each page has exactly one H1 tag. If missing, add a unique H1 tag to the page that accurately summarizes its content.
DUPLICATE H1: Each H1 tag should be unique on its respective page. Review all H1 tags and make sure none are repeated. Modify duplicates to ensure uniqueness.
OVER 70 CHARACTERS: Keep H1 tags concise and informative, ideally under 70 characters to ensure they display properly in search engine results.
MULTIPLE H1s: Each page should contain only one H1 tag for clarity and SEO best practices. If there are multiple H1 tags, consolidate or restructure them into one meaningful heading.
ALT TEXT IN H1: Avoid using ALT text (alternative text for images) within H1 tags. H1 tags should only contain text that directly represents the main heading of the page.
NON-SEQUENTIAL H1: Ensure that H1 tags are used in a logical and sequential manner that reflects the hierarchy of the content on the page. The H1 should typically be the most important heading on the page and should be followed by logically nested headings (H2, H3, etc.).

CONTENT

Exact Duplicates:

Identify duplicates: Use tools like Screaming Frog, Copyscape, or Google Search Console to find exact duplicate content.
Consolidate or delete: Decide whether to merge duplicate pages into one or use canonical tags, or remove low-value duplicates.

Near Duplicates:

Rewrite content: Ensure each page offers unique value.
Add unique elements: Include unique insights, examples, or case studies to differentiate content.

Low Content Pages:

Evaluate content: Assess pages for thin content (less than 300 words or lacking depth).
Expand or consolidate: Combine pages if topics overlap or expand content with more comprehensive information.

Soft 404 Pages:

Check server responses: Verify if pages return correct HTTP status codes.
Improve content: Ensure pages provide relevant content matching user intent to avoid soft 404 errors.

Spelling Errors:

Use spell check tools: Run content through tools like Grammarly or Microsoft Word for spell check.
Manual review: Proofread content for contextual errors that automated tools may miss.

Grammar Errors:

Grammar check: Use tools for grammar like Grammarly or Hemingway Editor.
Manual editing: Review content manually to correct grammatical mistakes for clarity.

Readability Difficult:

Simplify sentences: Break down complex sentences into shorter ones.
Use headings and lists: Structure content with headings, subheadings, and lists for easier reading.

Readability Very Difficult:

Rewrite content: Simplify complex concepts using plain language.
Use readability tools: Check readability scores and aim for lower grade levels (typically 6th to 8th grade readability).

Lorem Ipsum Placeholder:

Replace with real content: Ensure all placeholder text is replaced with meaningful content.
Complete content: Fill in missing sections with relevant information that meets user expectations.

IMAGES

1. Images over 100KB

Problem: Images are too large in file size, which can slow down page loading times.
Solution: Use image optimization tools to compress images without significantly reducing quality. Aim for a balance between file size and image quality.

2. Missing alt text

Problem: Alt text (alternative text) is not provided for images, which is important for accessibility and SEO.
Solution: Add descriptive alt text to each image that describes its content or function. This helps visually impaired users understand the image and improves SEO.

3. Missing alt attribute

Problem: Some images lack the alt attribute altogether.
Solution: Ensure that every <img> tag has an alt attribute. Even if the image is purely decorative, use an empty alt attribute (alt="").

4. Alt text over 100 characters

Problem: Alt text is excessively long, which can be cumbersome for accessibility tools and may not be necessary.
Solution: Keep alt text concise and descriptive. Ideally, it should convey the essence of the image in a few words.

5. Missing size attributes

Problem: Size attributes (width and height) are not specified for images.
Solution: Specify the width and height attributes in the <img> tag. This helps browsers allocate space for the image before it loads, improving page layout and rendering speed.

6. Background images

Problem: Background images may not have accessibility features like alt text.
Solution: For background images used in CSS, provide alternative content or context directly in the HTML, especially if the background image is informative.

7. Incorrectly sized images

Problem: Images are displayed at sizes larger or smaller than their actual dimensions.
Solution: Ensure images are displayed at their native size or resized appropriately using CSS or HTML attributes (width and height). This prevents distortion and improves performance.

Canonicals

1. Check for Canonical Tag Existence

Firstly, ensure that each page on your website has a canonical tag in the <head> section. This tag helps search engines understand the preferred version of a page if there are duplicates or similar content.

How to Fix:

Review your website's HTML code for each page (<head> section) and confirm the presence of a canonical tag (<link rel="canonical" href="URL">).

2. Self-Referencing Canonical Tags

Self-referencing canonical tags point to the same URL as the page itself. This scenario does not provide any SEO benefit and should be avoided.

How to Fix:

Make sure that the href attribute of the canonical tag points to a different URL (if applicable) that represents the preferred version of the page.

3. Canonicalized Pages

Ensure that canonical tags are correctly implemented on paginated or parameterized pages to consolidate link equity and avoid duplicate content issues.

How to Fix:

Implement canonical tags on paginated pages to point to the main page or a representative page in the series.

4. Missing Canonical Tags

Pages without canonical tags can lead to SEO issues, especially if there are duplicate versions of the same content accessible through different URLs.

How to Fix:

Add canonical tags to all pages, specifying the preferred URL that search engines should index.

5. Multiple Canonical Tags

Having multiple canonical tags on a single page can confuse search engines and potentially harm SEO efforts.

How to Fix:

Ensure each page has exactly one canonical tag pointing to the preferred URL.

6. Conflicting Canonical Tags

Conflicting canonical tags occur when different canonical tags point to different URLs for the same page.

How to Fix:

Review canonical tags across your site and ensure consistency. All versions of the same page should point to the same canonical URL.

7. Non-Indexable Canonical Tags

Canonical tags should only be placed in the <head> section of HTML documents. Placing them elsewhere might render them non-functional.

How to Fix:

Verify that all canonical tags are correctly placed within the <head> section of your HTML.

8. Relative Canonical URLs

Canonical URLs should be absolute URLs (beginning with https:// or https://) rather than relative URLs.

How to Fix:

Modify canonical tags to use absolute URLs (href="https://www.example.com/page " instead of href="/page").

9. Unlinked Canonical Tags

Ensure that canonical tags are not only present but also correctly linked to within the <head> section of each page.

How to Fix:

Check the HTML source code to confirm that canonical tags are properly included and linked.

10. Canonical Tags Outside lt;headgt;

Canonical tags should strictly be placed within the <head> section of HTML documents. Placing them elsewhere can lead to functionality issues.

How to Fix:

Move any canonical tags found outside the <head> section to the correct location within <head>.

Pagination

1. Contains Pagination

Issue: Pages have pagination but there are problems with its implementation.
Fix: Ensure that pagination is correctly implemented following standard practices (e.g., using rel=“next” and rel=“prev” for series of pages, or rel=“canonical” for consolidated pages).

2. First Page

Issue: The first page of paginated content might not be properly optimized or indexed.
Fix: Make sure the first page of paginated content is optimized for SEO with unique content, proper meta tags, and relevant keywords.

3. Paginated 2+ Pages

Issue: Content is spread across multiple pages, affecting user experience and SEO.
Fix: Consider implementing a "Load more" button or infinite scroll instead of pagination, or ensure pagination is user-friendly with clear navigation and consolidated content indexing.

4. Pagination URL Not in Anchor Tag

Issue: URLs for pagination are not properly structured within anchor tags.
Fix: Ensure pagination links are correctly formatted within anchor tags (<a> tags) for proper HTML structure and SEO best practices.

5. Non-200 Pagination URLs

Issue: Pagination URLs return HTTP status codes other than 200 (e.g., 404, 301, 302).
Fix: Ensure all pagination URLs return a 200 OK status code to indicate they are accessible and correctly functioning.

6. Unlinked Pagination URLs

Issue: Pagination URLs are not properly linked or accessible from the main content or sitemap.
Fix: Ensure all pagination URLs are linked correctly from the main content and sitemap to ensure search engines can crawl and index them.

7. Non-Indexable

Issue: Pagination pages are set to noindex, preventing search engines from indexing them.
Fix: Check and update meta robots tags to allow indexing of pagination pages if they contain valuable content. Alternatively, ensure rel=“canonical” tags are correctly set to consolidate indexing signals.

8. Multiple Pagination URLs

Issue: Different URLs lead to the same pagination content, causing duplicate content issues.
Fix: Implement rel=“canonical” tags on pagination pages to specify the preferred URL for indexing or use 301 redirects to consolidate URL variations.

9. Pagination Loop

Issue: Users or search engines encounter an endless loop when navigating pagination links.
Fix: Debug and fix the code responsible for pagination to prevent infinite loops. Ensure pagination links are correctly implemented with proper logic to avoid cycling through the same set of pages.

10. Sequence Error

Issue: Pagination pages are not displayed in the correct order.
Fix: Check the pagination logic to ensure pages are displayed in the correct sequential order (e.g., from first to last). Verify that navigation links (next/previous) are correctly structured and functioning.

Directives

Index: Indicates the page should be indexed by search engines.
Noindex: Directs search engines not to index the page.
Follow: Instructs search engines to follow links on the page.
Nofollow: Directs search engines not to follow links on the page.

NoTranslate: Instructs translation services not to translate the page content.
Unavailable_After: Specifies when search engines should stop displaying the page in search results.
Refresh: Automatically refreshes the page after a specified time period.

Placing Meta Tags Outside lt;headgt;

According to HTML specifications, meta tags should be placed within the <head> section of your HTML document. Placing them elsewhere might not be valid HTML and can lead to unpredictable behavior across different browsers and search engines. However, if you need to include meta directives outside the <head> for specific reasons (though not recommended), here are potential approaches:

Using <meta> Tag in <body> Section

:

<body>

????<meta name="robots" content="noindex, nofollow">

????

</body>

Using HTTP Headers:
Example .htaccess configuration: arduino Header set X-Robots-Tag "noindex, nofollow"

Hreflang

1. Contains hreflang

Ensure that each page that targets multiple languages or regions includes correct hreflang attributes in the <head> section of the HTML.

2. Non-200 hreflang URLs

Make sure that all hreflang URLs return a status code of 200 (OK) when accessed. Non-200 status codes indicate issues such as redirects, errors, or inaccessible pages.

3. Unlinked hreflang URLs

Verify that each hreflang URL specified on your pages has a corresponding link back to the current page. Each hreflang link should be reciprocal.

4. Missing Return Links

Check that each page with hreflang attributes links back to itself using the correct hreflang code. This self-referencing ensures consistency and completeness.

5. Inconsistent Language & Region Return Links

Ensure that the hreflang links are consistent across your site, using the correct language and region codes as specified in your hreflang attributes.

6. Non-Canonical Return Links

Confirm that all hreflang URLs point to the canonical version of each page. This helps search engines understand the preferred version of your content.

7. Noindex Return Links

Make sure that pages referenced in hreflang attributes are not set to 'noindex' in your robots meta tags. 'Noindex' pages will not appear in search engine results.

8. Incorrect Language & Region Codes

Double-check that all hreflang attribute values use correct language and region codes according to ISO standards. Incorrect codes can lead to ineffective targeting.

9. Multiple Entries

Avoid duplicate or conflicting hreflang entries for the same page. Each combination of language and region should be unique and accurate.

10. Missing Self Reference

Ensure that each page includes a self-referencing hreflang tag. This tag indicates the language and region of the current page itself.

11. Not Using Canonical

Always use the canonical tag to specify the preferred version of each page. This helps search engines consolidate indexing signals for duplicate or similar content.

12. Missing X-Default

Include an 'x-default' hreflang attribute for pages that serve as default or unspecified language/region versions of your content.

13. Missing Outside lt;headgt;

Place all hreflang attributes within the <head> section of your HTML pages. Placing them elsewhere may lead to incorrect or ineffective indexing by search engines.

JavaScript

Pages with Blocked Resources

Issue: Some resources (like JavaScript files, CSS, images) might be blocked from being crawled by search engines or users.
Fix: Ensure that all necessary resources are accessible by checking and updating your robots.txt file and server configurations. Unblock any essential resources.

Issue: Links that are crucial for SEO are generated or updated via JavaScript, making them inaccessible to search engines that do not execute JavaScript.
Fix: Implement server-side rendering or use progressive enhancement techniques to ensure critical links are present in the HTML when first loaded.

Contains JavaScript Content

Issue: Important content is rendered or updated using JavaScript, which might not be indexed by search engines.
Fix: Use server-side rendering or pre-rendering techniques to ensure that all content, especially important for SEO, is present in the initial HTML.

Noindex Only in Original HTML

Issue: The noindex directive might only be applied after JavaScript execution, potentially leading to search engines indexing pages you intend to exclude.
Fix: Ensure that noindex directives are applied in the initial HTML response, regardless of JavaScript execution status.

Nofollow Only in Original HTML

Issue: Similar to noindex, nofollow directives should be present in the original HTML to prevent search engines from following specific links.
Fix: Implement nofollow attributes directly in the HTML or through server-side rendering to ensure they are applied correctly.

Canonical Only in Rendered HTML

Issue: Canonical URLs should be present in the initial HTML to guide search engines properly, even if JavaScript modifies them.
Fix: Ensure that canonical URLs are set in the HTML served by your server and not just after JavaScript execution.

Canonical Mismatch

Issue: There might be discrepancies between canonical URLs set in different versions of the page.
Fix: Standardize the canonical URL across all versions of the page to avoid confusion and consolidate SEO signals.

Page Title Only in Rendered HTML

Issue: Page titles should be present in the initial HTML for SEO purposes, regardless of JavaScript usage.
Fix: Include page titles directly in the HTML served by your server to ensure they are immediately available to search engines.

Page Title Updated by JavaScript

Issue: Page titles updated dynamically by JavaScript may not be indexed correctly by search engines.
Fix: Ensure that the initial HTML response includes the correct page title. Dynamically update titles using JavaScript after ensuring they are correctly indexed.

Fix: Serve initial meta descriptions in HTML and update them using JavaScript afterward, ensuring they are correctly indexed.

H1 Only in Rendered HTML

Issue: H1 headings should be in the initial HTML for SEO, regardless of JavaScript.
Fix: Ensure H1 tags are present in the HTML served by your server. Update dynamically using JavaScript as needed after ensuring indexing.

H1 Updated by JavaScript

Issue: Dynamically updated H1 tags may not be indexed correctly by search engines.
Fix: Serve initial H1 headings in HTML and update using JavaScript afterward, ensuring they are indexed properly.

Uses Old AJAX Crawling Scheme URLs

Issue: URLs use deprecated AJAX crawling schemes that are not optimal for SEO.
Fix: Update your site to use modern JavaScript frameworks that support history API and clean URLs. Implement server-side rendering or dynamic rendering for SEO-critical content.

Uses Old AJAX Crawling Scheme Meta Fragment Tag

Issue: Meta fragment tags for AJAX URLs are outdated and not recognized well by search engines.
Fix: Remove meta fragment tags and implement clean URLs with proper history API usage in modern JavaScript frameworks.

Pages with JavaScript Errors

Issue: JavaScript errors can prevent proper rendering and indexing of your pages.
Fix: Debug JavaScript errors using browser developer tools and fix them to ensure all content renders correctly.
