Technical SEO best practices fall into 3 groups: requirements, recommendations, and folklore. Google’s documented requirements are short: Googlebot is not blocked, the page returns an HTTP 200 status, and the page has indexable content. Everything else is a recommendation that helps, plus a long tail of “must-dos” with no documented effect.

This guide sorts the technical SEO best practices into those 3 groups, gives you a 30 minute audit that uses Google’s own free tools, and ranks fixes by what to do first. The examples come from Connecticut service business sites, but nothing here is location specific.

Key Takeaways

• Technical SEO best practices start with Google’s 3 documented requirements: Googlebot is not blocked, the page returns HTTP 200, and the page has indexable content.
• Core Web Vitals are a recommendation. Google highly recommends good scores and says they align with what its ranking systems reward, but they do not replace relevant content.
• Google says AI Overviews and AI Mode need no special markup or AI text files, so skip “AI technical SEO” add-ons.
• Fix in this order: the 3 requirements, then Core Web Vitals, then internal links and structured data.
• On WordPress, a site left set to discourage search engines can keep a new site out of Google after launch.
• Lorphic’s website SEO audit checks the 3 requirements first, and fixes are billed at $15/hr.

Which Technical SEO Best Practices Does Google Actually Require?

Only 3. Google’s technical requirements page says a page is eligible for indexing when Googlebot is not blocked, the page works and returns HTTP 200, and the page has indexable content. The same page says getting into search results costs nothing, so anyone selling indexing as a paid secret is overselling.

Requirement	What breaks it	How to check
Googlebot is not blocked	robots.txt rules, login walls, CDN or firewall rules, noindex tags	Search Console Page Indexing and Crawl Stats reports, URL Inspection
Page returns HTTP 200	404 pages and server errors	URL Inspection shows the status code
Page has indexable content	Text in unsupported file types, spam policy violations	URL Inspection and the live page text

On WordPress, check 2 launch settings first: the search engine visibility box under Settings, Reading, and any staging copy that stayed public. Both are quick to test and both are easy to miss.

Which Technical SEO Best Practices Are Recommendations, and Which Are Folklore?

Sort every item on a technical checklist into 3 labels before you pay to fix it: Required, Recommended, or No documented effect. The table below does that for items that appear on most technical SEO best practices lists. Evidence means a statement in Google’s own documentation, checked on November 4, 2026.

Practice	Label	Evidence
Googlebot is not blocked	Required	Google’s technical requirements
Page returns HTTP 200	Required	Google’s technical requirements
Indexable content	Required	Google’s technical requirements
Good Core Web Vitals	Recommended	Google highly recommends them in its Core Web Vitals page
Crawlable internal links	Recommended	Listed in Google’s AI features SEO checklist
Important content in text form	Recommended	Same checklist
Structured data matching visible text	Recommended	Same checklist
Business Profile details up to date	Recommended	Same checklist
Special AI schema, AI text files, or markup	No documented requirement	Google says none is needed for AI Overviews or AI Mode
A perfect 100 lab score	No documented target	Google’s targets are good Core Web Vitals, not a lab score
Hiding pages with robots.txt	Wrong tool	Google points to noindex and snippet controls to limit what shows

Notice what is missing from the Required rows: speed scores, schema, and AI files. Those can help, but none of them decides whether a page is eligible to be indexed.

Technical SEO Best Practices 1 to 3: The Requirements

1. Make sure Googlebot can reach the page

Google only indexes pages that are public and do not block Googlebot. Pages blocked by robots.txt are unlikely to appear in results, and a login wall stops crawling entirely. Google’s AI features guide adds that crawling should also be allowed by any CDN or hosting layer.

• Open yourdomain.com/robots.txt and look for Disallow: / under a rule that applies to Googlebot or all bots.
• Run 3 money pages through URL Inspection and read the crawl and index status.
• Compare the Page Indexing report with your list of important pages.

2. Serve a 200 status on every page you want indexed

Google only indexes pages served with an HTTP 200 status, and error pages are not indexed. A service page that returns 404 after a redesign is simply gone from Search. Check the status with URL Inspection, then restore the page or redirect it to its closest match.

3. Put your content in indexable form

Indexable content means text in a file type Google supports that does not violate its spam policies. Google’s AI features guide also lists making important content available in textual form as a best practice. Put your services, service area, and phone number in real text, not only inside images.

Technical SEO Best Practices 4 to 9: The Recommendations

These 6 are not gates, but Google names them in its own guidance, so they are the safest places to spend time after the requirements pass.

4. Pass Core Web Vitals on real visits

Google’s Core Web Vitals page highly recommends good scores and says they align with what its core ranking systems seek to reward. The targets are LCP of 2.5 seconds or less, INP of 200 milliseconds or less, and CLS under 0.1, measured on real user visits rather than one lab run. They support good content but do not replace it.

• LCP: resize and compress the hero image, and avoid loading it lazily above the fold.
• INP: remove or delay heavy third-party scripts such as chat widgets.
• CLS: set width and height on images and embeds so the layout does not jump.

The web design best practices guide covers how these targets fit with mobile design decisions.

#	Practice	What good looks like	Check with
5	Crawlable internal links	Every important page is linked from at least 1 other page with a descriptive anchor	A site crawler orphan page report
6	Mobile content parity	The same main content and links appear on mobile and desktop	URL Inspection rendered page
7	Structured data matches visible text	LocalBusiness or Organization data repeats details visible on the page	Google’s Rich Results Test
8	Consistent business details	Name, address, phone, and hours match the site and Google Business Profile	Business Profile and site footer
9	Monthly monitoring	Page Indexing, Crawl Stats, and Core Web Vitals are reviewed monthly	Search Console

How Do You Run a 30 Minute Technical SEO Audit With Free Tools?

You can test every requirement and most recommendations among these technical SEO best practices with free tools. Give yourself 30 minutes and work in this order.

Step 1 (5 minutes): Open the Search Console Page Indexing report. Note which pages are not indexed and the reason listed for each.

Step 2 (5 minutes): Open the Crawl Stats report under Settings. Look for spikes in errors or slow server responses.

Step 3 (5 minutes): Run URL Inspection on your 3 highest value pages. Confirm each is indexed, returns 200, and shows your services in the rendered text.

Step 4 (5 minutes): Open robots.txt, and on WordPress check the search engine visibility setting under Settings, Reading.

Step 5 (5 minutes): Run PageSpeed Insights on the same 3 pages and read the mobile tab. Record LCP, INP, and CLS.

Step 6 (5 minutes): Use a free crawler to confirm each money page has at least 1 internal link pointing to it.

Which Technical SEO Mistakes Waste the Most Time?

These 5 mistakes appear on many technical SEO best practices checklists, and each one sends effort in the wrong direction.

Mistake	Why it fails	Do this instead
Using robots.txt to hide pages	Google points to noindex and snippet controls to limit what shows in Search	Use noindex on pages you want out of results
Adding AI-specific markup or text files	Google says none is needed for AI Overviews or AI Mode	Spend the hours on the 3 requirements
Chasing a perfect lab score	Google’s targets are good Core Web Vitals on real visits	Fix the metric that fails on your slowest template
Tuning speed while pages are not indexed	A fast page Google cannot index earns no search traffic	Pass the 3 requirements first
Auditing once and never again	Plugin, theme, and redirect changes can break a working site	Review Search Console monthly

Decision Framework: Which Technical SEO Best Practices Should You Fix First?

Symptom	Likely cause	First fix	Skip for now
A new page is not in Google	Blocked, noindex, non-200 status, or no internal link	URL Inspection, then fix the reported cause	Speed tuning
A page is indexed but does not rank	Relevance or competition more than technical issues	Improve how well the content matches the query	More technical tweaks
The site is slow on phones	Heavy images or scripts	Fix the Core Web Vital that fails	Rewriting all content
Local service pages are missing from results	Orphan pages or thin duplicates	Add internal links and merge duplicates	Pages for more towns
A vendor sells “AI technical SEO”	A markup or file add-on	Ask which Google documentation requires it	Paying for it

How Does Lorphic Apply Technical SEO Best Practices for Connecticut Businesses?

Lorphic, a digital marketing agency in Guilford, CT, checks the 3 requirements before anything else, because speed and schema work cannot help a page Google cannot index. Its website SEO audit reports which requirements pass, which Core Web Vitals fail, and which fixes come first.

Fixes are scoped on the $15/hr full-service model, so a small business pays for the hours a fix takes. For local visibility on top of the technical base, see the local SEO guide.
