You can write the best content in the world, optimize every title tag, and earn links from every major site in your industry. But if your website does not meet Google’s basic technical requirements, none of it matters. Your pages will not show up in search results, period.
The good news is that Google’s technical requirements are surprisingly simple. There are only three of them. Here is what they are, why they matter, and how to make sure your site passes.
Requirement 1: Googlebot Is Not Blocked
Google uses automated programs called crawlers (or Googlebot) to discover and read your website. If something on your site is telling Googlebot to stay away, your pages will not get indexed. It is that simple.
robots.txt restrictions
This is a file on your server that tells crawlers which pages they can and cannot access. A misconfigured robots.txt can block your entire site from Google without you realizing it. One common mistake is leaving a “Disallow: /” directive in place after launching a site that was in development. Always review your robots.txt file after any site migration or launch.
Server-level blocks
Some hosting providers or security plugins block crawlers they do not recognize. If Googlebot gets a “403 Forbidden” error, it moves on. Firewall rules, DDoS protection services, and aggressive bot-blocking plugins are the most common culprits. If you use Cloudflare or a similar service, make sure its security settings are not interfering with legitimate search engine crawlers.
Meta robots tags
Adding noindex to a page tells Google not to include it in search results. This is useful for private pages, but devastating if accidentally added to your important pages. Some WordPress themes and SEO plugins add noindex tags by default to certain page types, so it is worth checking your archive pages, tag pages, and category pages to make sure they are not accidentally hidden.
You can check if Google can access your site by using the URL Inspection tool in Google Search Console. It will tell you exactly what Googlebot sees when it visits any page on your site.
Requirement 2: The Page Actually Works
When Google requests your page, your server needs to respond with an HTTP 200 (success) status code. If your page returns a 404 (not found), 500 (server error), or keeps redirecting in a loop, Google cannot index it.
This sounds obvious, but broken pages are one of the most common SEO problems on local business websites. They happen when:
- You delete a page but other sites still link to it
- You redesign your site and the URLs change
- Your hosting has intermittent outages that you do not notice
- A plugin breaks and returns errors on certain pages
Using 301 redirects properly
Google’s recommendation is to use 301 redirects when URLs change. A 301 redirect tells Google “this page has permanently moved to this new address,” and it transfers most of the ranking signals to the new URL. Avoid redirect chains (Page A redirects to Page B which redirects to Page C), as each hop dilutes the signal. Keep redirects as direct as possible.
Monitoring server uptime
If Google tries to crawl your site and your server is down, it will come back later. But if this happens repeatedly, Google may reduce how often it crawls your site, which delays indexing of your new content. Affordable hosting is fine, but make sure your host maintains solid uptime. A free or ultra-cheap hosting plan that goes down regularly can silently hurt your SEO.
Requirement 3: The Page Has Indexable Content
Even if Google can access your page and it loads fine, Google still needs to be able to read the actual content. Some formats are harder for Google to process.
Text in images
If your entire page is one big image with text baked into it, Google cannot read that text. It sees an image file and nothing else. Use real HTML text for your headings, paragraphs, and product descriptions. If you must include text in images (like a logo or infographic), add alt text that describes the content.
Flash and other obsolete formats
If your site still uses Flash, it is invisible to Google (and most modern browsers). Replace it with standard HTML. This is rarely an issue on modern sites, but older sites built in the late 2000s or early 2010s may still have Flash elements hiding on certain pages.
JavaScript-only content
Google has gotten much better at rendering JavaScript, but if your page relies entirely on client-side JavaScript to display content, there is a risk Google will not see it. Make sure critical content is in the initial HTML response. If you use a JavaScript framework like React or Angular for your site, look into server-side rendering or static generation to ensure Google can read your pages without executing scripts.
Meeting the Requirements Is Not Enough
Here is the catch that catches a lot of people: meeting these three technical requirements means your pages are eligible to be indexed. It does not mean they will be indexed. Google still has to decide that your page is worth including in search results.
That decision is based on the quality and relevance of your content, the user experience of your site, and hundreds of other factors. But if you fail the technical basics, you never even get to that evaluation. Think of these three requirements as the cover charge to get into the club. Paying it does not guarantee you a seat, but not paying it means you are standing outside.
Tools to Check Your Technical SEO
You do not need expensive software to audit your technical SEO. Here are free tools that cover the essentials:
- Google Search Console: The single most important tool. It shows indexing errors, crawl stats, mobile usability issues, and Core Web Vitals data. Every site owner should have this set up.
- Google PageSpeed Insights: Tests your page load speed on mobile and desktop and gives specific recommendations for improvement. Speed is a ranking factor, especially on mobile.
- Screaming Frog SEO Spider: The free version crawls up to 500 URLs and finds broken links, redirect chains, missing title tags, and noindex tags. Perfect for small business sites.
- URL Inspection Tool: Built into Search Console, this tool shows you exactly how Google sees any individual page. It tells you whether the page is indexed, when it was last crawled, and what (if any) errors were found.
Run your site through these tools once a month, or after any major site change, and you will catch most technical problems before they affect your rankings.
How to Check Your Site Quickly
Here is a quick checklist any business owner can run right now:
- Search
site:yourdomain.comon Google. If your pages show up, Google is finding and indexing them. - Open Google Search Console and check for errors on your property page.
- Click through your own website on your phone. If pages load slowly or throw errors, fix those first.
- Check that your important pages have real text content, not just images.
If all of that checks out, you are meeting Google’s technical requirements and can focus on the content and optimization side of SEO. If you want to learn more about building content that ranks, check out our guide on writing content that ranks on Google.
