What are rich snippets?

What are rich snippets?

Ever searched in Google and saw a ginormous ranking just above the search results?… These large search results are called “rich snippets” and can send a mind-blowing amount of traffic.

What are rich snippets?

Before I jump into techniques, still not sure what I’m talking about? Quickly Google a couple of questions and look for the giant search result at the top of the results, you can’t miss it—it’s four times bigger than a regular search result. Here’s example searches that usually deliver a rich snippet in the results, “what are rich snippets”, “how to get started in real estate”, “how to increase your blog traffic”, and so on…

Why you need to focus on rich results.

Considering banging your head against the wall, wondering why you’re reading such a soul-destroying dry topic? Well, don’t throw this book out the window just yet…

These new technologies allow greater control over search listings, making it easier for search engines to crawl your site, potentially featuring your content as a “rich result” appearing at the top of the results, helping you get higher click-through rates and get more eyeballs on content. Think of this technology like meta tags on steroids…

Still not convinced? With voice search predicted to be 50% of searches by the end of 2020 by Comscore, and 40% of voice search results originating from rich results, targeting rich-results is a must—if you want to get amongst the rising voice search trend.

Why use Structured Data and JSON-LD?

To tell Google which parts of your content you want considered for a rich result, you need to use code called “structured data.” With new technologies, as always, there’s a debate about the best to use—JSON-LD, RDFa, microdata, the list goes on…

I won’t waste your time with a technical debate. Google has openly stated JSON-LD is the preferred code—and made it clear not to mix structured data technologies for fear of confusing the search engine spider…

We’re here for high rankings and traffic, not a lengthy diatribe on each individual technology, so let’s go with what Google recommends for the purposes of this book—JSON-LD.

How to get started with JSON-LD.

So, what does all this JSON-LD structured data stuff look like? Let’s look at a business listing to see how it should be coded, according to Google’s recommendations.

<script type=”application/ld+json”>

{

“@context”: “https://schema.org”,

“@type”: “Organization”,

“url”: “http://www.example.com”,

“name”: “Unlimited Ball Bearings Corp.”,

“contactPoint”: {

“@type”: “ContactPoint”,

“telephone”: “+1-401-555-1212”,

“contactType”: “Customer service”

}

}

</script>

The JSON-LD example code from Google gives the search engine a friendly nudge to recognize the information as a business listing, such as the name and the phone number.

While the above example will be just enough if you have a simple business listing, you or your developer will have to use Google’s documentation and tools, listed later in this chapter, to ensure your code is implemented correctly.

How to target featured snippet rankings in Google’s search results.

After you’ve uploaded a bunch of fancy JSON-LD code into your site, you’re probably wondering when you appear at the top of the results… Using JSON-LD is just one step, if you want to achieve the coveted featured snippet ranking, you’ll need to satisfy the following requirements.

1. Rank on the first page, first. Almost all featured snippets are fetched from rankings on the first page. Follow techniques from the On-Page SEO and Link building chapter and work your way up the results first.

2. Create “snippet bait” targeting 40-50 words. SEMrush did a giant study on rich results and featured snippets, finding almost all text-based rich snippets range between 40 to 50 words.

3. Structure your content to target featured snippets. Hint: putting target keywords as H2 or H3 headings, followed with clear and concise paragraphs around 40-50 words, is a solid approach.

5. Use images. Featured snippets often contain images, I like to call them “snimmages”—for some reason, this terminology never really caught on like I hoped… Using images increases chances for both text and images appearing in the featured snippet. According to Google’s official guidelines, images should be at least 1200 pixels wide. And using multiple high-resolution images with aspect ratios 16×9, 4×3, and 1×1 can help with appearing on different devices.

How to target “People also ask” and question-based rich results.

There’s another popular type of rich snippet appearing for almost any question type search—the “People also ask” rich snippet. Fortunately, some clever SEOs have figured out general techniques for targeting these sexy rankings.

1. Your desired ranking must be a question type keyword. Searches not phrased as a question won’t always trigger a “People always ask” snippet, best focus on question type keywords.

2. Your answer should be clear and concise. Well-written and clear answers have a much greater chance of being featured then poorly written answers. Remember the 40-50 words technique from earlier in this chapter.

3. Include a Q&A or how-to section on your site. Increase content in a question and answer format and increase your odds of being featured for question-type searches.

4. Provide more valuable information than a simple and direct answer. If your answer has numbered lists, rich media such as images and videos, and is generally more helpful than an obvious answer to the question, then you have a greater chance of being featured.

5. Add Google’s recommended question-type JSON-LD code to relevant pages… While this won’t guarantee results, it’ll encourage Google to look at your pages and consider them for use in the rich results. Recommended JSON-LD code is listed at each of the following pages.

Voice search SEO and Google’s Speakable structured data.

With the rise of miniature circular voice speaking robots invading people’s homes—virtual assistants like Alexa and Google Assistant—it comes with little surprise Google is making moves to capture this market, and you can too!

Before we cover Google’s “Speakable” markup, and how any business can optimize for voice search, you might be wondering why voice search is important—after all, you want customers to read content on your site, not have it spoken aloud, right?

Well, not necessarily… If voice searchers find a solid voice answer, they are likely to visit your site. Voice search is in an upward trend and best viewed as an additional source of traffic, not something that will take away from current traffic. Now we’ve established it’s worthwhile putting voice search optimization on the radar, lets jump into the gritty details.

Implementing Speakable for US based news publishers.

Implementing Speakable is straightforward. Firstly, you need to be a US based news publisher. Secondly, you need to submit your site for consideration in Google’s Publisher Center. Finally, you will need to direct your site developer to review Schema.org’s technical guidelines and implement the code on your site. Review the following resources and get started.

Google – Speakable and Submission for Eligibility

Schema.org – Speakable Developer Documentation

Voice Search Optimization for regular site owners and marketers.

We’re not all US-based news publishers and it’s understandable regular site owners and marketers want to jump on the voice search bandwagon. While voice search optimization is new, a handful of techniques have been established by industry insiders. Implement these and you will increase your chances of having your words of wisdom echoed by a voice speaking robot in a stranger’s home.

– Short answers in substantial content… Pages with over 2000 words appear more frequently in search results than articles with 500 or so words. Within long-form content, include short-form content, in a question and answer format, using short and concise answers, following the 40-50 word rule mentioned earlier.

– 65% of voice search results use HTTPS and have SSL certificates installed… If you’ve read this far and haven’t installed an SSL certificate, I’m starting to get a little concerned.

– Focus on building an authoritative site in your niche—relevant links, high value content, active social profiles, and so on.

– Make sure your website loads fast—4.6 seconds or faster to be precise. A large portion of voice searches are performed on mobile devices with slow Internet connections.

Facebook Open Graph.

While we know schema.org is the best approach for adding meta data to your site, there is one additional meta data technology you should also use.

Facebook’s Open Graph language allows you to determine how your site listing appears when shared on Facebook.

If you do not include Facebook’s Open Graph code on your site, when a user shares your content on Facebook it will show a plain listing on the news feed, with the responsibility on the user to describe the article and make it worth reading. If you include Facebook Open Graph code, it comes up looking sexy, just like your search listings if you have been using your meta title and meta description tags correctly.

By putting your best foot forward, and making your listing show up correctly on Facebook, you will encourage more customers to click to your site and increase the amount of likes and shares for your page. This will increase the overall social signals of the page.

Here’s an example of properly formatted meta code using Facebook Open Graph. As you can see, there are only minor tweaks required to make your page show up nicely on Facebook’s news feed. So go ahead and use it on your site!

<title>Buy Baseball Jackets Online</title>

<meta property=’og:type’ content=’site’>

<meta property-‘og:description’ name=’description’ content=’Wide range of Baseball Jackets online, for all leagues and players. Free delivery and free returns both-ways in USA.’/>

If you’re worried about confusing search engines by using several “structured data” technologies at the same time, such as Open Graph and schema.org, don’t worry, you won’t have any problems.

Facebook Open Graph is mainly used by Facebook’s web crawler, not by search engines, so you can use Open Graph and schema.org in tandem without any problems.

Bonus chapter 1: Google’s algorithm updates.

You need to be informed about Google’s updates to ensure your site doesn’t trigger Google’s spam filters. In some cases, you can take advantage of updates to the algorithm and get higher rankings. In this chapter I will walk you through the biggest updates over the years that you should be aware of. And at the end of this chapter, I will show you resources for catching wind of the newest updates as they are released. Let’s get started.

Google’s Interstitial update – A.K.A. “Death to mobile popups.”

Google announced on the Google Search Central Blog on January 2017, sites displaying obtrusive “interstitials” to mobile users wouldn’t rank as high in the search results, and this type of advertising behavior would be banished from the cosmos! If you’re wondering what “interstitial” means, it’s Silicon Valley tech-speak for a popup ad.

Let’s have a quick read over the announcement from the team at Google and then look at what this update means for businesses:

“Here are some examples of techniques that make content less accessible to a user:

Showing a popup that covers the main content, either immediately after the user navigates to a page from the search results, or while they are looking through the page.

Displaying a standalone interstitial that the user has to dismiss before accessing the main content.

Using a layout where the above-the-fold portion of the page appears similar to a standalone interstitial, but the original content has been inlined underneath the fold.”

Helping Users Easily Access Content On Mobile

https://developers.google.com/search/blog/2016/08/helping-users-easily-access-content-on

In other words, with the exception of cookie verifications and legal notices, age verifications, and app install banners, all other popups will lead to poor performance in the mobile search results.

I’m on the fence on this update, I know from experience a lot of site owners and business owners achieve significant sales from subscribers that sign up to their popups. Dictating the marketing of site owners to such a degree could be considered an over-reach from Google. By making it more difficult for site-owners to maximize the sales of their website visitors, is Google encouraging site owners to spend more money on Google Ads and remarketing campaigns to encourage more customers to return to their site?… I’ll let you decide.

On the other hand, a significant number of sites load unnecessarily slow and make mobile web browsing a clunky, slow and unreliable experience. Quite often, the cause of the slow loading is the site owner clogging up their site with complicated scripts and files that power the popup ads—sorry, I mean interstitials. Google has played a significant role in nudging website owners to update their technology and make browsing the web an effortless and usable experience, which is good for the Internet community as a whole.

Whatever your feelings about this update, this is going to be a positive change for users. The way we browse the web on our phones will become faster and more reliable as a result. Just ensure you disable mobile pop-ups or you will likely see some drop-offs in your mobile search visitors. Death to popups, long live browser notifications!

Accelerated Mobile Pages—A.K.A. Mobile web browsing on steroids.

Have you ever asked yourself, “What are Accelerated Mobile Pages all about, exactly?” If you haven’t, then maybe you should, because the behemoth open source project known as Accelerated Mobile Pages can help sites get a major boost in the search results. So much so, the Google team announced on September 12, 2016, on the Google Search Central Blog that sites equipped with the Accelerated Mobile Pages technology are going to be rewarded with “expanded exposure.” The descriptions are noticeably vague, like most statements from Google, but before jumping to conclusions let’s look at what Accelerated Mobile Pages are all about, exactly.

Accelerated Mobile Pages is a collaborative effort between Google, and a gazillion notable publishing companies around the globe, such as Mashable, The Guardian, The New York Times, and many others. The development teams of these organizations have been working together to craft a new technology making mobile web browsing faster, to a significant degree. To their credit, pages enabled with the Accelerated Mobile Pages technology are noticeably fast, snappy and responsive when you view them on your phone.

Specifically, Accelerated Mobile Pages is a framework, or a set of tools and guidelines, enabling web developers to build web pages that load blazingly fast. The core elements of AMP involve a specific approach to coding HTML, a JavaScript library that speeds up the delivery of files, and a caching network provided by Google that ensures speedier delivery of the files.

Some examples of techniques AMP employs to make mobile web browsing super-fast include:

1) Only allowing asynchronous scripts. Quite often websites won’t load the page until particular scripts have been downloading in full, with this new restriction it will only accept scripts that load in the background and don’t block the loading on the page.

2) Only running GPU-accelerated animations. Believe it or not, some webpages use unreasonably complicated scripts causing your mobile’s processor to slow down, with this restriction the AMP creators are forcing simpler calculations on websites that can be processed quickly by the graphics processor on your phone.

3) Pre-rendering, A.K.A. loading pages in advance. Another powerful technique, pre-rending intelligently loads pages you are likely to visit in the background, so that when you get around to visiting them there’s no need to wait for it to download.

The above examples are only a few of the many techniques the authors of AMP use to make websites load significantly faster on mobile phones. If you want to check out which platforms support this technology, the folks over at the AMP project have created a list of websites currently providing AMP capability.
