Technical SEO is the part of SEO that helps Google crawl, understand and index your website properly. It also helps customers use your site without running into slow pages, broken links, confusing redirects or forms that do not track correctly.
For Auckland and New Zealand businesses, technical SEO is especially important when you are competing in busy local search results. You might have helpful services, good reviews and a strong team, but if Google cannot access the right pages — or customers leave because the website is slow — your rankings and enquiries can suffer.
The good news is that technical SEO does not need to be mysterious. A lot of it comes down to careful checks, clear page structure and fixing issues before they become bigger problems.
PMGS Digital helps Auckland businesses with SEO services in Auckland that include technical SEO, local SEO, content, tracking and plain-English reporting. This checklist explains the technical SEO areas we recommend reviewing regularly.
Quick technical SEO checklist
If you want the short version, start with these checks:
- Make sure important pages can be crawled and indexed by Google.
- Check Google Search Console for indexing errors, manual actions and sitemap issues.
- Keep your sitemap and robots.txt file clean and accurate.
- Fix broken internal links and unnecessary redirect chains.
- Redirect old high-value URLs to the closest relevant new page.
- Improve page speed and Core Web Vitals where they affect users.
- Make sure the website works well on mobile.
- Use clear titles, headings, canonical tags and meta descriptions.
- Add structured data where it genuinely helps Google understand the page.
- Keep local business details consistent across your website and Google Business Profile.
- Track calls, forms and key conversion actions — not only traffic.
- Recheck everything before and after website rebuilds or migrations.
Technical SEO is not about chasing every tiny score. It is about removing the issues that stop your website from being found, understood and used.
1. Check that Google can crawl your website
Google needs to crawl your pages before it can rank them. If important pages are blocked, hidden or buried too deep, they may not perform as well as they should.
Check:
- your important service pages are linked from the navigation, footer or relevant internal pages
- your robots.txt file is not blocking key sections of the website
- important pages are not marked
noindexby mistake - Google Search Console can inspect and fetch key URLs
- your XML sitemap includes the pages you actually want indexed
- deleted, duplicate or thin pages are not cluttering the sitemap
For a service business, your main commercial pages should be easy to find. For example, pages such as SEO Auckland, Google Ads Auckland, web design Auckland and social media marketing Auckland should not be hidden several clicks away.
2. Review indexing in Google Search Console
Crawling and indexing are related, but they are not the same thing. Google might crawl a page but decide not to index it. Sometimes that is fine. Sometimes it means an important page is missing from search results.
In Google Search Console, review:
- pages indexed by Google
- pages discovered but not currently indexed
- pages crawled but not currently indexed
- duplicate pages without user-selected canonicals
- not found errors
- redirect errors
- sitemap submission status
Do not panic if some URLs are excluded. Many websites have old, duplicate or low-value URLs that should not be indexed. The priority is to make sure your important service, location, blog and contact pages are indexable and useful.
3. Keep your sitemap clean
Your XML sitemap should be a clear list of the pages you want search engines to find. It should not be a dumping ground for every old URL.
A good sitemap should:
- include live canonical URLs
- exclude redirected URLs
- exclude 404 pages
- exclude admin, tag, search and thin utility pages unless there is a clear reason
- update when new content is added
- use the preferred URL format consistently
Keep the sitemap focused on live canonical pages, and review it whenever services, locations or articles are added or removed.
4. Fix broken links and redirect chains
Broken links create a poor experience for visitors and waste crawl signals. Redirect chains can also slow things down and make migrations messier than they need to be.
Check for:
- internal links pointing to 404 pages
- old blog URLs that no longer have a relevant destination
- redirect chains such as URL A → URL B → URL C
- temporary redirects where permanent redirects are more appropriate
- internal links that still point to old URLs instead of the final destination
If a page has been replaced, redirect it to the closest relevant new page. Do not redirect every old URL to the homepage by default. That may be easy, but it is not always helpful for users or search engines.
For example, an old SEO service page should redirect to the current SEO Auckland service page, not to a generic page.
5. Protect important old URLs during website changes
Website rebuilds and migrations are common times for SEO issues to appear. A new website can look better and still lose visibility if old URLs, titles, content, redirects and tracking are not handled carefully.
Before launching a new site, create a simple migration checklist:
- export the current top landing pages from Google Search Console
- export URLs with impressions, clicks, backlinks or conversions
- map old URLs to the closest new URLs
- keep important page topics and headings aligned with search intent
- set up 301 redirects before launch
- test redirects after launch
- submit the updated sitemap
- monitor Search Console daily during the first few weeks
- check forms, phone tracking and analytics events
This is especially important for Auckland businesses with established local rankings. Even pages with low clicks may have useful impressions, internal links or local relevance.
6. Improve page speed where it helps users
Page speed matters because customers do not want to wait. A slow website can reduce enquiries, especially on mobile.
Check:
- large images that can be compressed or converted to modern formats
- unused scripts or heavy third-party tools
- slow hosting or server response times
- render-blocking assets
- layout shifts as the page loads
- forms, maps, chat tools or tracking scripts that slow key pages
Tools such as PageSpeed Insights and Lighthouse can be useful, but do not treat scores as the only goal. A fast, stable service page that helps customers enquire is more valuable than a perfect score on a page nobody uses.
7. Check Core Web Vitals
Core Web Vitals are Google’s user experience metrics for loading speed, interactivity and visual stability.
The main checks are:
- Largest Contentful Paint (LCP): how quickly the main page content loads
- Interaction to Next Paint (INP): how responsive the page feels when someone interacts
- Cumulative Layout Shift (CLS): whether page elements jump around while loading
For most Auckland businesses, focus first on the pages that drive enquiries: service pages, location pages, campaign landing pages, the homepage and contact pages.
8. Make the mobile experience simple
Many local searches happen on mobile. Someone might search during a lunch break, while travelling, or while comparing providers quickly.
Check that mobile visitors can:
- read the page without zooming
- tap phone numbers easily
- find the contact form
- use the navigation
- understand the service quickly
- see trust signals and reviews
- load pages on mobile data
Technical SEO and conversion rate optimisation overlap here. If users cannot comfortably enquire, rankings alone will not solve the problem.
9. Use clear page titles, headings and canonicals
Technical SEO also includes basic page-level signals. Each important page should have a clear topic and a clear job.
Check:
- one clear H1 per page
- title tags that match the page intent
- meta descriptions that explain the page and next step
- canonical tags pointing to the preferred version of the page
- no accidental duplicate pages targeting the same keyword
- headings that help users scan the page
For example, a page targeting SEO services should not also try to be the main page for web design, Google Ads and social media. It can link to those services, but the page itself needs a focused purpose.
10. Add structured data where it is useful
Structured data helps search engines understand information on your website. It does not guarantee rich results, but it can support clarity.
Useful schema types for many NZ business websites include:
- LocalBusiness or Organisation schema
- WebSite schema
- WebPage schema
- BreadcrumbList schema
- FAQ schema where FAQs are visible on the page
- Article schema for blog content
- Service schema where appropriate
Only mark up information that is actually visible and accurate. Avoid spammy schema or fake reviews. Structured data should support the truth of the page, not exaggerate it.
11. Check local SEO technical signals
Technical SEO and local SEO work together. If your business serves Auckland or specific suburbs, your website should make that easy to understand.
Check:
- your name, address and phone details are consistent where shown
- your contact page is easy to find
- service areas are explained clearly
- location pages are useful, not copied templates with suburb names swapped in
- your Google Business Profile links to the most relevant page
- internal links connect local pages to main service pages
For example, a local content article can link naturally to SEO services in Auckland and to related service pages such as web design Auckland where the topic supports it.
12. Track real enquiries, not only traffic
Good technical SEO should support better measurement. If tracking is missing, it is hard to know whether your SEO work is creating business value.
Check that you can measure:
- contact form submissions
- phone clicks
- email clicks
- booking or audit requests
- key landing-page conversions
- Google Business Profile actions where available
- paid and organic traffic separately
For PMGS, the preferred message is simple: SEO should be measured against real enquiries, not vanity metrics alone.
13. Review security and trust basics
Trust is part of the user experience. It also affects whether customers feel safe making contact.
Check:
- HTTPS is active across the full website
- mixed-content warnings are fixed
- forms work correctly and securely
- spam protection does not block real enquiries
- privacy and contact information are easy to find
- outdated plugins, themes or dependencies are not creating risk
This is especially important for businesses that collect customer details, booking requests or quote information.
14. Avoid duplicate and thin pages
Many local SEO problems come from trying to create too many similar pages. A page for every service, suburb and keyword variation can quickly become thin or repetitive.
Before creating a page, ask:
- Does this page help a real customer?
- Is the search intent different from an existing page?
- Can we add useful local detail?
- Is there a clear next step?
- Will this page be maintained over time?
If the answer is no, it may be better to improve an existing page instead.
15. How often should Auckland businesses run a technical SEO check?
A sensible schedule is:
- Monthly: Search Console coverage, broken links, sitemap, key conversion tracking
- Quarterly: crawl audit, page speed review, internal linking, schema checks
- Before any launch: full redirect map, metadata review, analytics checks, form testing
- After any launch: indexation monitoring, redirect testing, traffic and conversion review
You do not need to rebuild your website every time an issue appears. Often, steady fixes are enough.
Common technical SEO mistakes to avoid
Here are the mistakes we see most often:
- launching a new website without a redirect plan
- blocking important pages in robots.txt
- accidentally adding
noindexto live pages - deleting old content without checking Search Console data
- redirecting too many old pages to the homepage
- using large images that slow down service pages
- tracking traffic but not enquiries
- creating thin suburb pages with copied content
- ignoring mobile forms and click-to-call actions
- treating SEO as a one-off setup instead of an ongoing process
Most of these are fixable. The key is to catch them early.

FAQs
What is technical SEO?
Technical SEO is the work that helps search engines crawl, index and understand your website. It includes checks for site structure, speed, mobile usability, redirects, canonicals, sitemaps, schema and tracking.
Is technical SEO different from local SEO?
Yes, but they support each other. Local SEO focuses on location-based visibility, Google Business Profile, reviews and service areas. Technical SEO makes sure the website behind that local presence is crawlable, fast, structured and measurable.
Do Auckland businesses need technical SEO?
Most do, especially if the website has been redesigned, migrated, expanded, or has lost traffic. Technical SEO is also useful when service pages are not being indexed or when tracking is not showing where enquiries come from.
How long does technical SEO take?
It depends on the size and condition of the website. Some fixes are quick, such as broken links or sitemap cleanup. Larger issues, such as migration recovery, speed improvements or site structure changes, can take longer.
Will technical SEO guarantee higher rankings?
No honest SEO provider should guarantee rankings. Technical SEO removes barriers and improves the foundations of the website, but rankings also depend on content, competition, authority, search intent and ongoing work.
What should I check before launching a new website?
Before launch, check redirects, metadata, page content, internal links, sitemap, robots.txt, analytics, form tracking, mobile usability and page speed. After launch, monitor Google Search Console closely for indexing and redirect issues.
Can PMGS help with a technical SEO audit?
Yes. PMGS provides SEO services in Auckland that include technical SEO reviews, local SEO, content recommendations and reporting focused on real enquiries.
