What Google's Past Algorithm Updates Can Teach You About SEO

What Google's Past Algorithm Updates Can Teach You About SEO

Google algorithm updates are considered something that marketers are always wary of. So, every time Google rolls out an algorithm update, they become nervous and have no option but to roll with the punches. However, Google releases hundreds of minor adjustments and a few significant tweaks to its algorithm every year.

In this article, we will discuss your ideal strategy in the wake of such updates so that it does not affect your traffic and rankings. We will also explain how you can use past algorithm updates to understand the current trends and deal with them.

In the past decade, the core objective of Google algorithm updates was to prevent manipulation of search engine algorithms by unscrupulous companies, so only the relevant sites may appear on the top SERPs resulting in a better search experience for the users.

What Are Google Algorithm Updates?

Now that Google has taken search experience to the next level, the search engine not only wants its users to get relevant results for their search queries, but it also wants them to be happy with the websites appearing on top of SERPs.

The focus of the previous updates used to be:

  1. Up-to-date, unique, and relevant content
  2. Trustworthiness of the website
  3. Link quality
  4. User experience (download speed, ease of navigation, and glitch-free checkouts, etc.)

It usually affects how a web page ranks on Google.

Google also wants to make sure its users love the content and their overall experience on the website.

So, all the authoritativeness and the backlinks are useless if the website doesn't offer a good user experience. So, for better or worse, The focus is now shifting towards user experience.

It's crucial to know since we want our readers not just to be ready for a particular update to be rolled out in the future but any algorithm update that Google may announce in the forthcoming years.

Apart from the regular algorithm updates, Google announces some sweeping updates every year to prepare proactively and update their websites accordingly.

A Brief Overview of Previous Google Algorithm Updates

Let's discuss some significant algorithm updates that changed many practices and changed the landscape of SEO across the web world.

1. Google Panda Update

The first serious update that shook the web world was the Panda, which Google announced in 2011. It was aimed at penalizing poor-quality content that offered very little value and was overstuffed with keywords.

Now, let's discuss the context of this update. Google announced this update at a time when most companies engaged in content farming. It was all about poor-quality content created for search engines. It mainly was irrelevant, least helpful for the users, and keyword stuffed. The aim of writing such articles was to game the search engine algorithms to win top rankings. As soon as Google decided to deal with this sneaky practice, Panda was rolled out to penalize those sites.

The timeline for the Panda algorithm update indicates that Google targeted thin content, high ad to content ratio, and various other quality issues. Google rolled it out in a phased manner in different countries, and finally, in September 2012, Panda #20 was announced, which was a significant update, affecting 2.4% of the queries.

Again in May 2014, Google announced a major Panda update that affected 7.5% of English language queries, and with these updates, Google almost tackled duplicate and poor quality content. Digital marketing teams across the globe started creating high-quality content that offers real value to the users. With this, the nefarious practice of keyword stuffing took a back seat and was replaced with the natural inclusion of relevant keywords.

2. Penguin Update

Google announced the Penguin update just a year after Panda was first rolled out in 2011, but its aim was entirely different. It was launched to deal with another significant menace in the web world— artificial link building used as a “hack” to win top ranks.

You must be familiar with the fact that Google has been taking backlinks as a sign of authority, popularity, and trustworthiness of a site since its inception. It openly uses it as a ranking signal.

Some unscrupulous webmasters decided to take advantage and started using it as a hack to rank on top manipulating Google's love for backlinks. Low quality and spammy backlinks led to reduced search results on Google as low-quality websites started ranking high. Google took it head-on with the Penguin update and started penalizing the sites involved in this practice. Soon a significant shift happened, and business owners and webmasters started tracking their links and removing low-quality, irrelevant and spammy links.

3. The Hummingbird Update

Google announced the Hummingbird update to provide a better experience to the searcher by showing the related results. For example, if someone searched for “small business,” Google will use different search intents to show the results. So, the results may include websites offering small business loans, business consultancy and networking services, small business ideas, small business trends, and government websites that connect entrepreneurs with lenders. For example, if you run a cake shop, you can optimize your website for the following keywords:

  • Cakeshop
  • Bakery
  • Cupcakes
  • Cheesecake
  • Birthday cake
  • Vegan bakery
  • Italian bakery
  • Sweetshop
  • Pastry shop

Even though the results don’t look like an exact match to your queries, they are relevant and valuable for the searcher. So, this up-date expected marketers to focus on related keywords as well apart from the main keywords.

How to Proactively Prepare Yourself Against Future Algorithm Updates?

If you want to keep your website “update proof” and don’t want to lose out on traffic because of every damn update, the best strategy is to learn from the past updates.

Here are a few tips you can proactively use to protect your website against any future algorithm updates:

1. Understand the Basics of Google Algorithm Updates

You can understand the central objective of Google update, and to a great extent, it was explained by Ben Gomes, Google’s Vice-President of Engineering, “our goal is to get you the exact answer you’re searching for faster.”

So, relevancy, accuracy, and rapidity are what Google wants to achieve with these updates. It makes understanding the search intent of the user essential. Marketers should focus on relevance and user experience, and it will cover almost everything Google expects from your website.

So, let’s begin with user experience. First, check how long it takes for your website to load. Have a look at the navigation. Is it user-friendly? Can you get to the sections you need to go in a maximum of three clicks? Are too many ads bothering you or preventing you from seeing the content on your web pages?

The recent changes made to Google’s algorithm point that sites with poor user experience will also get penalized regardless of other factors that might have propelled them to the top ranks.

2. Optimize UX

As per a shocking study by Google, as page load time increases from one to 10 seconds, the bounce rate of a mobile site visitor may go up by 123%. So, if you are serious about retaining visitors to your site, you should minimize the page load time.

Reducing the number of ads, especially near the critical navigation buttons, is also a good way of optimizing the UX. It would help if you kept in mind that users won't close the three random ads and would instead close the website and move to another site.

How to Identify That a Google Algorithm Update Has Affected Your Site?

Here's a checklist you can follow to determine whether your website has been affected by a recent Google algorithm update:

1. Track Google Updates

Keep on tracking Google updates and find out if there have been any recently. Most Google algorithm updates that occur almost daily are industry-specific and their effect only in specific industry verticals. Their objective is to improve the search results. Specific algorithm updates are also referred to as core updates on the flip side, and these updates happen several times a year.

If you want to know about the latest algorithm updates and how they can affect your website, check out Moz’s list of Google algorithm updates. The following screenshot explains the updates that happened in 2021 and how they impacted search results. For example, the latest update was detected by many SEO tools in February 2021, and it was named “Featured Snippets Drop.” Its likely impact was that Google Search started showing featured snippets less often (SEL).

2. Wait For the Dust to Settle

Don't panic as soon as you sense an update taking place. Let the dust settle down, which takes around a week. It would help if you didn't react to things in the meantime. Once the data stops fluctuating, you can initiate the repair. You can refer to Google Analytics and Google Search Console after that and take cues from these channels.

3. Check Google Analytics

Now it's time to get back to Google Analytics and Google Search Console and choose different date ranges to see any traffic fluctuations. To access Search Console via GA, go to Acquisition > Search Console

Sometimes, this fluctuation can be due to an external factor such as running an email or any other promotion campaign, or a big event or holiday, so you should choose a broader date range.

If you see an overall decline in your traffic or a sharp drop in your organic sessions or leads, it can be due to a Google algorithm update.

4. Check It Across Different Landing Pages

Log in to Your Site's Google Analytics Account > Go to Acquisition > Search Console > Landing Pages

If traffic drop is sitewide, it could be due to an algorithm update.

Website Traffic Drop

Similarly, you can also check it across different devices.

Acquisition > Search Console > Devices > Click on Mobile

Usually, a sitewide traffic drop is a strong indication that your website has been affected by an algorithm update.

5. Perform the Preliminary Assessment: Check Google

There is another method that you can try with ease. If you feel that your website has been affected by an update, check the search landscape on Google. Also, check the current position of your website as compared to your competition:

a. Is there a significant change in the positions?
b. Which site is ranking at the position your site used to rank before?
c. Are you still ranking but in no-click search results, snippets, or paid ads?
d. Compare the rankings of your web pages to those that are now ranking well. Compare the keywords you are targeting versus them? Find out if they are using any keyword variations or content strategies?
e. Have they implemented any specific landing page strategies you haven’t tried so far which may help you boost your rankings?

6. Check Your Backlinks Profile

Sometimes you may notice a drop in traffic due to the presence of spammy links. As Google may penalize your site anytime if they detect spammy links, it's essential to check your backlink profile regularly. You can use Google Search Console for auditing your backlinks. You can also manage your backlink profile and improve the overall health of your backlinks through GSC.

Here is the step-by-step process of checking your backlink profile using SEO SpyGlass and Google Search Control:

A. Get the comprehensive list of your backlinks

Open SEO SpyGlass and enter your domain name. SEO SpyGlass provides a comprehensive list of backlinks as it uses its own index to find backlinks.

New Backlink Research Project

For better results, you can sync your Google Analytics and Google Search Console account with SEO SpyGlass. To do this, put a tick in front of the Enable Expert Options line, and click Next.

New Backlink Research SpyGlass

You can also turn it on using the “Preferences drop-down” menu of the tool.

Connect GSC in SEO SpyGlass

Once Google Analytics and GSC are connected to the tool, it will start retrieving the backlink data. However, the process may take some time.

B. Identify potentially harmful backlinks

Google ignores occasional bad backlinks, but an overwhelming number of suspicious backlinks may attract a manual penalty. Here is how to identify toxic backlinks.

In the tool, Go to Backlink Profile and then click the Penalty Risk section from the drop-down menu. On this screen, the tool will provide you with the estimated penalty risk for the backlink domains.

A backlink with a penalty risk of over 70% is considered a harmful and high-risk backlink. These are marked red, and you should remove those backlinks.

C. Remove toxic backlinks

The best option to remove toxic backlinks to your website is to disavow them. You can do it with the help of the Google Disavow tool. Google wants you to use this tool to inform them that these backlinks should be ignored when assessing your site for ranking purposes.

To do it, create a “disavow” file where you can collect all the toxic links and submit this file to the Google Disavow tool.

If you are using SEO SpyGlass, select the backlinks you want to remove and choose the Disavow backlinks option by right-clicking on it.

Disavow Backlinks in SpyGlass

Export the file from the tool and submit it to the Google Disavow tool as we did it previously.

You may not notice any immediate impact of this activity on your backlink profile, but Google will soon start ignoring these backlinks.

You should frequently do a backlink health check for your website and remove toxic and harmful links this way.

7. Keep Google’s Resolution and Mission Statement in Mind

As emphasized above, Google wants to offer the best user experience and exact search results faster. So, if you notice a drop in rankings or traffic, check whether your website provides:

a. Excellent user experience
b. Great and compelling content
c. Excellent usability

8. Use External Google Algorithm Update Trackers

To keep yourself abreast with the latest Google algorithm updates, you may refer to the following trackers.

A. Moz Update History: This list is maintained by none other than SEO guru Rand Fishkin’s Moz. It’s a comprehensive and up-to-date list of algorithm updates so that you can identify the trend.

a. Danny Sullivan: @dannysullivan and @searchliaison

What are Bulimia, Anorexia, & Eating Disorders? The article is written by Emily Mendez, M.S., Ed.S., a certified psychotherapist and an expert in mental health and substance abuse cases. It increases the trustworthiness of the website for the website visitors.
