What is Technical SEO and Why it Matters
Technical SEO refers to the behind-the-scenes optimization of a website to maximize crawlability, indexation and ranking potential in search engines like Google. It focuses on ensuring search engines can easily access, interpret and index your pages correctly.
Strong technical SEO is essential because it creates the foundation upon which your entire SEO strategy is built. If search engines struggle to crawl your site or interpret your content, even the best content and backlink building efforts will be futile.
Some key elements of technical SEO include site architecture, URL structure, use of structured data, Crawl Budget allocation, page speed and more. Many technical factors are direct or indirect ranking signals that impact your search visibility.
In summary, technical SEO helps search engines:
- Easily crawl your site and discover new content
- Interpret and make sense of your pages
- Index your important pages properly
- Rank your pages for relevant search queries
By optimizing these technical aspects, you ensure search engines can interpret your site as intended, leading to higher rankings, more traffic and better conversions over the long run.
Conducting a Technical SEO Audit
The first step towards improving technical SEO is auditing your current website to identify issues and gaps.
Here are some key things to review in a technical SEO audit:
- Indexation: Are all important pages indexed, especially new content? Are any pages blocked via robots.txt or meta noindex?
- Crawl Errors: Does Google Search Console show crawl errors like 404s or 500s preventing pages from being crawled?
- Duplicate Content: Are there any issues with near-duplicate or thin content diluting equity?
- Structured Data: Is structured data being implemented properly and passing testing tools?
- Page Speed: Are page speed metrics like Time to First Byte, Largest Contentful Paint and Cumulative Layout Shift optimized?
- Mobile Friendliness: Is there a mobile-friendly and mobile-first indexed version of the site?
- Security: Is the site served over HTTPS and using the latest web best practices?
- XML Sitemap: Is a comprehensive sitemap in place and submitted to search engines?
- robots.txt: Is the robots.txt file optimized and providing access to important pages?
conduct a full audit using tools like Google Search Console, Moz’s Site Crawl, Screaming Frog SEO Spider, and Google’s PageSpeed Insights. This will help you identify the highest priority issues to address first.
Optimizing URL Structure and Internal Linking
The structure of your URLs and overall site architecture impacts how easily search engines can crawl your site. Here are some best practices:
- Short, descriptive URLs: Use short URLs with relevant keywords, not overly long parameter-heavy URLs.
- Logical hierarchy: Structure your site into logical hierarchies and categories.
- SEO-friendly paths: Paths should be lowercase, hyphen-separated and avoid stop words.
- Individual page URLs: Each page should have its own URL, not dynamically generated parameters.
- Persistent URLs: Avoid frequent URL changes that break existing backlinks or indexes.
- Keyword targeting: Target 1-2 primary keywords per URL segment where it makes sense. Don’t over-optimize.
Internal linking is also important for crawlability and spreading equity across your site. Some tips:
- Link to related content with contextual anchor text, not broad over-optimized phrases.
- Make important pages easy to navigate to from site-wide elements like the menu.
- Implement breath-first crawling by linking pages from general to more specific.
Ensuring Proper Indexation and Crawlability
It’s critical that search engines can easily find, crawl and index your website pages. Here are some tips:
- Submit an XML sitemap listing all pages to be indexed.
- Set proper robots.txt directives to allow/disallow page crawling.
- Implement canonical tags on duplicate or alternate pages to signal the preferred URL.
- Use the “noindex” meta tag sparingly and only on pages not intended for search.
- Check for crawl errors in Search Console and address any blocking pages from being indexed.
- Optimize page speed and response times so pages load quickly. Slow sites lead to limited crawl budgets.
- Implement structured data where applicable to help search engines understand page content.
Eliminating Duplicate Content Issues
Duplicate content on a site can confuse search engines and dilute the effectiveness of your content. Here’s how to address it:
- Use canonical tags to indicate the preferred or master page that other versions should consolidate signals/equity to.
- Create distinct content for each page, don’t copy-paste content across multiple URLs.
- For common templates like “About Us”, add unique text/images for each location’s version.
- Implement redirects for old pages or URL variations to direct SEO value to the canonical version.
- Disable or noindex archive or paginated pages where duplicate content naturally occurs.
Leveraging Structured Data and Schema Markup
Structured data and schema markup provide additional context and understanding of your content in search engines’ eyes.
Key technical implementation tips:
- Use schema types that make sense for your content (Product, Recipe, Article, Local Business etc).
- Fully complete required properties, don’t leave fields blank.
- Ensure structured data is valid via Google’s Structured Data Testing Tool.
- Focus on FAQ schema, breadcrumb schema and aggregate ratings where applicable.
- Avoid structured data just for the sake of it. Consider your high-value pages.
Optimizing Images and Media
Images and video are an important part of many websites. Ensuring they are optimized gives search bots better signals.
- Use relevant file names with target keywords for image files and alt text.
- Add schema metadata to images like captions and copyright information.
- Compress oversized images to improve page load speeds.
- Insert captions and transcriptions to videos to aid understanding.
- Optimize videos for voice search with proper title, description and captions.
Using XML Sitemaps and robots.txt Properly
Providing XML sitemaps and a well-structured robots.txt file helps search engines efficiently crawl your site.
For sitemaps:
- Create and submit an XML sitemap of all important pages on your site.
- List pages from most to least important to focus crawl budget.
- Only include pages you want indexed, not everything.
- Split into multiple sitemap files if exceeding maximum URL limits.
- Update sitemap frequently as new content is added to the site.
For robots.txt:
- Allow crawling of all pages you want indexed with
Allowdirectives. - Selectively disallow unimportant pages like archives, logs etc.
- Don’t block site crawl tools which ignore robots.txt by default.
- Test robots.txt using validation tools before deploying live.
Improving Site Speed and Core Web Vitals
Site speed impacts crawl efficiency, user experience, and search ranking factors.
- Optimize images, scripts, files for faster load times.
- Minify CSS, JS and HTML files. Eliminate render blocking resources.
- Enable caching and compression to reduce file sizes.
- Defer non-critical JS/CSS so above the fold content loads first.
- Optimize server response times and Time to First Byte speeds.
- Fix Core Vitals issues around LCP, CLS, FID to improve user experience.
- Test page speed using Lighthouse, PageSpeed Insights and WebPageTest.
By optimizing these technical SEO elements, you ensure search engines can efficiently crawl, index, understand and rank your important website pages. While technical SEO alone won’t grow your traffic, it establishes a scalable foundation to build upon with great content, user experience and marketing.
