- Audit after every redesign or migration.
Why Technical SEO Matters
You can write excellent content and collect great reviews, but if search engines can’t properly crawl and understand your website, rankings will suffer. Technical SEO covers the foundation: how pages are discovered, rendered, indexed and delivered to visitors.
For local businesses, technical problems are common. Websites built years ago may have outdated code. Redesigns may break links. Plugins may slow pages. Duplicate pages may confuse search engines. Many of these issues are invisible to owners until rankings drop.
This checklist covers what we review in technical audits for local business websites.
1. Indexing
Check That Important Pages Are Indexed
Use Google Search Console to see which pages are indexed and which are excluded. Look for important service, location and blog pages that aren’t indexed.
Look for Accidental Noindex Tags
Sometimes developers add “noindex” during development and forget to remove it. Check key pages.
Review Robots.txt
Make sure robots.txt doesn’t block important pages or resources such as CSS and JavaScript.
Submit an XML Sitemap
An XML sitemap lists important pages. Submit it in Search Console and keep it updated.
2. Crawlability
Fix Broken Links
Broken internal links create dead ends. Use crawling tools to find and fix them.
Avoid Redirect Chains
Multiple redirects in sequence slow crawling and users. Redirect directly to the final URL.
Use Internal Links
Link related pages, such as service pages to location pages and blog posts to services. Internal links help search engines discover and understand pages.
3. Site Structure and URLs
Use Clean URLs
URLs like /services/water-heater-repair/ are clearer than /page?id=123.
Organize Logically
Group pages into sections, such as services, locations and blog. Use breadcrumbs.
Avoid Duplicate Content
Duplicate pages, such as the same content at multiple URLs, confuse search engines. Use canonical tags to indicate preferred versions.
4. Mobile Usability
Most local searches happen on phones. Check:
- Text is readable without zooming.
- Buttons and links are easy to tap.
- Content fits the screen without horizontal scrolling.
- Forms are easy to complete.
- Phone numbers are tappable.
5. Speed and Core Web Vitals
Core Web Vitals measure loading performance, responsiveness and visual stability. Slow, unstable pages frustrate users.
Common Fixes
- Compress and resize images; use modern formats like WebP.
- Lazy-load images below the fold.
- Minimize heavy scripts and plugins.
- Use caching and a content delivery network.
- Reduce third-party scripts, such as unnecessary trackers.
Test pages with PageSpeed Insights and Search Console reports.
6. Security
Use HTTPS across the entire site. Make sure there are no mixed content warnings. Keep platforms and plugins updated to reduce security risks.
7. Structured Data
Add schema markup for your business, services, articles, FAQs and breadcrumbs. Validate markup and fix errors.
8. Title Tags and Meta Descriptions
Each page needs a unique title tag describing its content, often including service and location. Meta descriptions should summarize the page and encourage clicks. Avoid duplicates.
9. Headings
Each page should have one clear H1 and logical subheadings. Headings help users and search engines understand page structure.
10. Images
Use descriptive file names and alt text. Alt text helps accessibility and image understanding.
11. Accessibility
Accessibility improves usability for everyone and aligns with many SEO best practices. Check color contrast, keyboard navigation, form labels and alt text.
12. Local Signals
Make sure your name, address and phone number appear consistently on the website, often in the footer and contact page. Embed a map on contact or location pages. Link to your Google Business Profile.
13. JavaScript Rendering
Some websites rely heavily on JavaScript. If important content only appears after scripts run, search engines may have trouble. Test how Google renders pages using Search Console’s URL inspection tool.
14. Migrations and Redesigns
Redesigns and platform migrations are common sources of SEO problems. Before launching:
- Map old URLs to new URLs.
- Set up 301 redirects.
- Preserve important content.
- Test thoroughly.
- Monitor Search Console after launch.
15. Monitoring
Technical SEO isn’t a one-time task. Review Search Console regularly for errors, coverage issues and performance changes. Run periodic crawls.
Prioritizing Fixes
Not every issue is equally important. Prioritize:
- Indexing problems on important pages.
- Broken pages and redirects.
- Mobile usability.
- Speed improvements.
- Structured data and metadata.
Example: A Redesign That Lost Rankings
A dental practice launched a beautiful new website. Within a month, calls from search dropped noticeably. A technical audit found that old service page URLs had not been redirected, so links from directories and search results led to error pages. The new site also used a staging setting that blocked indexing on several pages.
The fix involved mapping every old URL to its new equivalent, adding redirects, removing the blocking setting and resubmitting the sitemap. Rankings recovered over the following weeks. A pre-launch technical checklist would have prevented the drop entirely.
Example: Speed Improvements for a Contractor
A roofing contractor’s website loaded slowly on phones because of large uncompressed photos and a heavy slider on the homepage. Compressing images, converting them to modern formats, removing the slider and limiting third-party scripts made pages noticeably faster. Bounce rates fell and more visitors tapped the call button.
Tools That Help
- Google Search Console for indexing, performance and Core Web Vitals.
- PageSpeed Insights for page speed diagnostics.
- A site crawler to find broken links, redirects and missing tags.
- Rich Results Test for structured data.
- Accessibility checkers for contrast and labeling issues.
Pre-launch Checklist for Any Website Change
Before launching a redesign or major update, confirm that every important old URL redirects to its new equivalent, that no pages are accidentally blocked from indexing, that the sitemap is updated, that title tags and headings are in place, that forms and call buttons work on mobile and that analytics and call tracking are installed. Ten minutes of checking can prevent months of lost visibility.
