0 / 18Technical SEO & Performance
Search engine crawlers parse HTML to understand your content. Errors in HTML can confuse them or break rendering.
- Use W3C validation tools to check for unclosed tags or syntax errors.
- Focus on critical structural errors rather than minor warnings.
Loading speed directly impacts technical SEO and user experience. "Green" scores (90+) are ideal.
- Optimize and cache images (use WebP/AVIF).
- Leverage browser caching and compress assets (Gzip/Brotli).
- Minimize blocking JavaScript and CSS.
Standard YouTube `
- Use a Facade pattern: display a thumbnail image with a play button.
- Load the actual iframe only after the user clicks the play button.
Google uses HTTPS as a ranking signal. A secure connection is mandatory.
- Ensure your SSL certificate is valid and not expiring soon.
- Force 301 redirects from `http://` to `https://`.
Avoid redirect chains and ensure legacy URLs map correctly to new ones.
- Configure `www` to `non-www` (or vice versa) uniformly.
- Remove trailing slashes consistently.
- Use HTTP 301 (Permanent) for moved pages.
A well-designed 404 page keeps lost users on your domain instead of bouncing back to search results.
- Include links to popular pages or the homepage.
- Include a search bar if applicable.
This file tells crawlers what they can or cannot visit.
- Ensure important directories are not `Disallow`ed.
- Include the absolute URL to your `sitemap.xml` at the bottom.
On-Page SEO & Content Strategy
URLs should be human-readable, descriptive, and keyword-rich.
- Good: `/seo-checklist` or `/services/web-development`
- Bad: `/page?id=123&sort=desc`
- Use hyphens to separate words. Keep them short.
Your core metadata must be completely unique for every indexable page to avoid keyword cannibalization.
- Title: 50-60 characters, primary keyword included.
- Description: 150-160 characters, compelling CTA.
- H1: Clearly describes the page content.
Headings communicate document structure.
- Only one H1 per page, usually at the top.
- Use H2 for major sections, H3 for sub-sections.
- Never skip levels (e.g., jumping from H1 directly to H3).
Search engines cannot "see" images. `alt` text describes the image function or content.
- Describe exactly what is in the image.
- Include keywords naturally, do not stuff them.
Filter combinations (e.g., "Red Shoes Size 40") can create millions of low-quality pages.
- Dynamically generate unique Title, Description, and H1 for indexable filter combinations.
- Use `rel="canonical"` or `noindex` for non-valuable filter states to preserve crawl budget.
Structure & Microdata
The sitemap provides a roadmap of all your important pages.
- Automate its generation so it STAYS updated.
- Only include status 200 URLs (no 404s or 301s).
Breadcrumbs help users and bots understand the site hierarchy.
- Display breadcrumbs near the top of the page (Home > Category > Product).
- Implement Schema.org BreadcrumbList markup.
Rich snippets increase CTR in search results.
- Implement JSON-LD for Article, Product, or FAQ.
- Add LocalBusiness or Organization schema for the homepage.
Global navigation passes "link juice" throughout your site.
- Link to main categories in the header.
- Place important utility links (Terms, Privacy, Contact) in the footer.
Setup & Analytics
You cannot improve what you cannot measure.
- Install GTM to manage all tracking scripts without code deployments.
- Set up GA4 to track traffic, bounce rates, and conversions.
Submit your site to webmaster tools to monitor indexing and errors.
- Google Search Console
- Bing Webmaster Tools
- Submit your `sitemap.xml` directly in these tools.
