Now, you’ve probably already reached out to other well-known SEO experts to address all sorts of website optimization issues. And you’d be hard-pressed not to have come across John Mueller’s various quotes along the way. Being one of Google’s top voices, Mueller is extraordinarily talented at cooling people’s doubts while also keeping Google’s secrets safe and sound. John has been a guiding hand for those who may not align with Google’s guidelines and is an advocate for the creation of really useful, unique, non-generic websites and quality content. He supports the concept of “Making the web you want to find”.

All that being said, if you work in the SEO industry, you need to keep John’s statements close to the chest. 

In this article, we will talk about John Mueller and his role at Google. We’ll also go over any of Mueller’s SEO insights that you may have missed.

Who is Google’s John Mueller?

John Mueller is the Senior Webmaster Trends Analyst and Search Relations team lead at Google. You might also know him as the Google Search Advocate. 

Google's John Mueller

Instead of diving head first into John’s SEO insights and recommendations, let’s start by taking a quick look at his background and career history before and during his experience at Google. This will help you understand why it’s important to listen to his advice if you haven’t already.

Before Google

John Mueller was born in Germany, but was raised in both the US and Switzerland. He received his higher education in Mechanical Engineering at ETH Zurich, a Swiss university. Before joining Google in 2007, he owned a software company in Switzerland for more than 12 years.

Career at Google

John Mueller’s start at Google began in September 2007. 

Being a Google Search Advocate, he focuses on helping webmasters and site owners understand how Google search works and how to improve their sites. In fact, he connects the Google-internal world of search engineering, to those who create and optimize public websites.

He’s also known for his regular Google SEO Office Hours, where he holds live Q&As with webmasters and SEOs. He regularly joins webmaster-related forums and speaks at industry conferences. Mueller is also active on Twitter and LinkedIn, and is generally available to answer users’ questions.

SEO insights from John Mueller

Now, let’s move on to the most exciting part: Mueller’s insights. Coming from someone who knows Google’s inner workings and is genuinely eager to help you, expect nothing short of gold. Each of John’s statements is grouped by category to help you find info within your topic of interest.

What SEOs are doing wrong

The primary goal of optimizing a website is to help Google find (and understand) your content. But some people make the mistake of thinking SEO is about manipulating search results to get higher rankings. Manipulating results actually dampens SERP quality. When lower-quality content somehow reaches the top, this makes users’ lives more difficult and motivates Google to work even harder to fix its algorithms.

Mueller has his own opinion on this.

Question at Mastodon to John Mueller
John Mueller's answer on black-hat SEO at Mastodon

SEO tricks like these go against Google’s guidelines. You might get temporary results, sure, but they’ll almost always lead to long-term failure.

That means you want to play fair, which also means you’ll be playing the SEO long game. Remember that SEO involves many processes, has an accumulative effect in some aspects, and requires constant effort. This can take the form of tasks like maintaining your site’s overall relevance, responding to Google’s constantly evolving algorithms, keeping an eye on competitors, and much more.

John Mueller supports genuine SEO. He often stresses how important it is to create search results that users value.

According to Mueller, there’s no magical formula for propelling your website to the top spot in Google. 

“Unfortunately there’s more to online success than just adding more pages. On the one hand, it’s important that things which you add actually bring new & unique value to the web. On the other hand, it’s important that your site overall is unique, compelling, of high quality, and also brings value to the web in ways that users recognize. None of this is trivial, it can take a lot of hard work to figure out what to focus on, where to expand, and where to simplify. And sometimes, it is possible to commit no mistakes and still not win. In short: there is no simple secret to online success.”

There is also no perfect SEO

“The internet, search engines and how user’s search is always changing. So SEO will evolve over time as well. This includes both technical elements, like structure data, as well as considerations around quality.”

Constantly searching for universal SEO tips and applying them to your site is not the way to go. Instead, Mueller advises investing time in creating valuable and unique content that is engaging and brings something new to the table. Be sincere to your audience and honest with Google. 

Keep in mind that having good search results takes a team effort. Google must work on improving search, and website owners must improve the quality of their pages. 

Content

The quotes below following the theme of content optimization, a key area in SEO. John actually talks about this concept a lot.

It’s common for SEOs to worry about having too many repeated keywords on their pages. The general consensus is that Google may interpret this behavior as an attempt to manipulate the website’s ranking. But having a high number of keyword entries is okay as long as the content remains useful to the reader. So whether it’s appropriate to include 10 or 100 keywords depends entirely on the content. This suggests that you should focus on quality over quantity.

  • Short content can still rank high.

Sometimes lengthy content is actually less valuable. For example, let’s say that a user is looking for a quick and precise answer to their question. A short post would have much better performance in this case than a long one. Some experts still believe that content must have a specific word count (let’s say, minimum 500 or 1000 words) to rank better, but even if this was partially true in the past, it’s not true at all now. As of today, word count has no direct impact on your ranking whatsoever.

  • Your website will not be penalized if it’s missing an H1 tag or has multiple on your page.

The H1 heading is an important element for structuring your content, but the absence of an H1 tag doesn’t necessarily have to spell disaster. Google’s algorithms are designed to understand webpage content, regardless if it includes an H1 tag or not. In fact, there are many websites that have high rankings but don’t use H1 tags.

John Mueller has also confirmed that Google doesn’t have any issues with pages that have multiple H1 tags. 

“Our systems don’t have a problem when it comes to multiple h1 headings on a page. That’s a fairly common pattern on the web. We use headings to better understand the context of different parts of a page. Our systems aren’t too picky and we’ll try to work with the HTML as we find it, be it one H1 heading, multiple H1 headings or just styled pieces of text without semantic HTML at all.”

Using multiple H1 tags is common practice among single-page websites.

  • Word location in URLs does not matter for SEO.

Many believe that word location within the URL impacts rankings, especially if it refers to e-commerce websites. The reasoning here is that they think it’s crucial to place /services/ before /location/ in the URL. But this really is not the case. All this does is influence the user experience and won’t provide any substantial benefits to search engines.

Backlinks

Next up on Mueller’s list of insights is off-page SEO. This is one of the main components of a successful website promotion strategy.

  • Domain authority is not a ranking factor.

Many SEO beginners think domain authority directly impacts Google rankings. But John Mueller reminds us that that’s not the case at all.

  • You can ignore spammy backlinks.

You can’t track all toxic backlinks. There is not much you can do about it anyway and spammers are going to be spammers. This is why John advises not to be overly concerned about links like these.

  • If you weren’t buying links, don’t disavow.

Google historically has not been a fan of folks using the disavow file. They even doubled down on it recently, so avoid doing it because it tends to do more harm than good anyway.

  • The donor website’s type doesn’t directly impact off-page SEO.

Some SEOs used to think that sites like news sources had more ranking power because they were considered “authority sites.” But that theory fell flat a long time ago. John Mueller recently clarified that all sites are treated the same, and what matters for PageRank is the site’s structure and how often it publishes content.

Technical SEO

Unlike on-page and off-page SEO (which focus on content and external factors), technical SEO often deals with the backend aspect of a site. It sets the foundation for the website’s overall SEO strategy. That being said, let’s find out John’s take on technical SEO.

  • Technical SEO still matters.

Mueller recently confirmed that technical SEO is still important. He has rejected claims that its significance is decreasing and believes that technical SEO is essential to ranking well in search engines. It also plays a key role in providing a good user experience, which is the most important factor.

  • Google Quality Updates may affect crawling and indexing.

Any changes made after updates affect more than just search positions. They also impact crawling and indexing. John Mueller reminded us of this on Mastodon:

John Mueller: Google Quality Updates may affect crawling and indexing

While CWVs will be used for ranking, they won’t instantly propel your website from page 10 to the number one position. Recently, John emphasized this point in the context of launching a new Interaction to Next Paint (INP) metric, which will replace First Input Delay, in March 2024.

“While improving INP can definitely help user experience, I wouldn’t expect it to visibly change search ranking.”

He also stated recently that Cumulative Layout Shift can’t be the reason for sudden ranking drops.

That’s it, Core Web Vitals is an important thing for users, but it’s not going to change everything completely.

  • HTML sitemaps should never be needed.

If you already have a clear navigational structure, why would you need an HTML sitemap that duplicates the same structure of your site? Now, it probably won’t cause problems, but, according to John Mueller, there’s no incentive to do it. Your best is to focus instead on improving the site structure.

  • Google may choose a syndication partner as the canonical source to rank.

If your website syndicates its content to partners, be prepared for the chance that Google will decide, for whatever reason, that the partner’s site is the canonical source and award that position to them. Recently, John Mueller confirmed this on X:

To prevent this issue, you can ask partner websites to use the noindex tag.

  • Update the URL address in Google Search Console when performing a website migration.

It’s recommended to update the URL address in Google Search Console during (not before) the migration. Google lacks data for the analysis of empty space, so it doesn’t make sense to change the URL address before the migration starts. It’s better to do it during migration because there will already be content on the new site for the search engine to process.

  • Having the wrong last modification date in your HTTP header won’t impact SEO.

It’s good to use last-modification date headers appropriately. This helps Google estimate how often pages are updated and to adjust its crawling more efficiently, but John Mueller says that neglecting this or doing it wrong won’t hurt your SEO.
