Google claims that thousands of adjustments are made to its search algorithm each year. Usually, Google algorithm updates are too minor to be seen. However, occasionally Google may make a change that is so big that it will forever transform how we conduct SEO.
The mystery behind Google’s search algorithm may be both irritating and fascinating for a digital marketer, content marketer, or SEO. There are innumerable publications out there that try to shed some light on this subject, but they frequently tend to be more speculative and subjective than anything substantive.
Every time someone searches on Google, algorithms are utilized to provide the best outcome or result. This task is carried out by more than one algorithm, and as it is supplied after the task, it also checks the rank of the websites. Google frequently changes its algorithm in significant ways.
In this piece, we’ll outline the ten most significant changes to the search algorithm. We’ll look at the reasoning behind these updates, how they work, and the adjustments to our SEO strategies that were subsequently required.
1. Panda
How it works: The Panda algorithm upgrade awards websites a “quality score” for their content. Despite Panda’s initial minor effects, it was eventually permanently incorporated into the core algorithm of Google in January 2016. Panda penalties and recoveries now occur more swiftly due to the increasing frequency of update rollouts since then.
How to adjust: Run routine site audits to check for keyword stuffing, weak content, and content duplication. You’ll need a site crawler, such as a Website Auditor from SEO PowerSuite or any other, to accomplish that.
You may also prevent a possible penalty and eliminate the chance of unintentional keyword stuffing when creating pages with the new Content Editor module of WebSite Auditor. The sites of your top competitors are examined by Content Editor, which offers SEO advice based on content that has already achieved success in Google searches.
2. Penguin
The purpose of Google Penguin is to reduce the ranking of websites that have dubious backlinks. This update did away with low-effort link-building strategies including obtaining links from link farms and PBNs.
How to adapt: To guard against the effects of the Google Penguin update, keep a watch on the evolution of your link profile and perform frequent audits using a backlink checker like SEO SpyGlass. The Summary dashboard of the program contains a growth progress graph for your link profile. A competitor’s poor SEO campaign may be the cause of any strange increases, so keep an eye out for them.
The Penalty Risk calculation in SEO SpyGlass incorporates the statistics that we are aware of being used by Penguin. Go to the Penalty Danger tab and rank the backlinks in your list from highest risk to lowest. Links with a risk of at least 50% ought to be looked at. Including them in the disavow file, downloading it, and submitting it to Google’s Disavow Links Tool is advised if they turn out to be dangerous.
3. Hummingbird
How it works: The Hummingbird algorithm is used by Google to more thoroughly examine searches and provide outcomes that are consistent with searcher intent. The Hummingbird algorithm permits pages to rank for a query even if they don’t exactly match the searcher’s exact terms, however, keywords are still very important. This is accomplished through the use of latent semantic indexing, co-occurring phrases, synonyms, and natural language processing.
How to adapt: Expand the scope of your keyword research and concentrate on the essential themes. Analyze synonyms, similar queries, and co-occurring phrases with care. Google Related Searches, Google Autocomplete suggestions, and Google Related Questions are all excellent places to find such ideas.
Utilize these insights to broaden your content selection and comprehend the language of your audience. Both engagement and SEO will benefit from producing thorough content that meets searcher intent.
4. Mobile
The emphasis is now on your website’s mobile version rather than its desktop equivalent as a result of this and planned mobile search updates (in 2018, 2020). Now, Google assigns a ranking to every page based on how quickly and effortlessly their mobile versions load.
How to adapt: By focusing on their speed and usefulness, make your pages mobile search-friendly. Use Google’s mobile-friendly and page speed tests to determine which parts of your page need to be improved. You can assess the tests’ integration with SEO Adelaide as part of your overall website audit to check how effectively your pages are optimized for mobile.
5. RankBrain
How it works: A component of Google’s Hummingbird algorithm is RankBrain. Google uses a machine learning system to help it interpret user intent and offer the most pertinent search results. Google ranks RankBrain as the third most important ranking factor.
It is widely acknowledged that RankBrain is in charge of tailoring a user’s Google search results, even though the precise mechanism driving this huge increase is undisclosed. In essence, Google takes into account factors other than the search query entered by the user, such as synonyms, implied terms, and previous search history.
How to adapt: Utilize competitive analysis to improve the comprehensiveness and relevance of your pages. Find a way to include all the terms in your content, and you will see a significant rise in search relevancy.
6. Medic
How it works: Websites that deal with potentially life-altering issues, such as those that are medical-related, appeared to be disproportionately impacted by the Google Medic upgrade (finance, law, education). The upgrade may have included some of the E-A-T signals from the Quality Rater Guidelines document, though this has not been expressly stated by Google employees.
How to adapt: Presently, there is no productive method for recovering from this update. Creating entities for your brand is the answer, according to some SEOs, while others advise hiring expert writers of SEO Adelaide to give your website credibility. But if we were to be truthful, building your backlink profile is the only proven approach to raising the authority of your website. Utilizing a backlink analysis tool and taking inspiration from your rivals’ backlink strategies might be an effective strategy.
Your best bets for customers are the high-authority websites that connect to two or more of your rivals. This demonstrates that while the websites are not solely connected to any one company, they are nevertheless interested in your market.
7. Bert
How it functions: Natural language processing is used by the new Google algorithm to better understand search requests, interpret the text, and identify entities and relationships among them. The BERT update is the culmination of this effort to move away from keywords, which was started with the Panda, Hummingbird, and RankBrain improvements. It allows Google to understand significantly more nuance in both queries and search results.
How to adjust: Finally, the time has come when Google will genuinely reward quality writing. Now more than ever, it’s critical to aim for a relevant copy. It implies that you should avoid using unnecessary words and write with an explanatory approach. When writing copy, it’s also a good idea to conduct entity research because integrating pertinent entities gives your content context.
8. Core Updates
How it works: As early as 2017, Google started referring to major updates as Google core updates. Since then, there has been even less openness about the specifics of those enhancements and the search categories they are intended to improve. Although SEOs routinely track post-update ranking adjustments and try to pinpoint what specifically has changed, a conclusive conclusion is rarely reached. Google core updates are likely merely minor adjustments to earlier Google updates or maybe a grouping of separate upgrades.
How to adapt: Since the effects of Google core changes are usually unclear, one thing you can do is keep an eye on the SERP history for the terms you’re targeting. Once the rankings have been updated, you can see which of your rivals have risen or fallen in the rankings and make an informed estimate as to what circumstances may have contributed.
9. Page Layout Algorithm
Google released this update on January 19, 2012. This algorithm was changed after the release on October 9, 2012, and the most recent update as of November 1, 2016, was made. The user experience is connected to this algorithm. This algorithm has an impact on websites with a lot of extra advertisements. Therefore, under this approach, those websites whose advertising forces users to view content were affected, and about 1% of websites.
10. Exact Match Domain
In 2012, this algorithm was released. As the name implies, it targets exactly what the name implies and operates on that name. Despite the site’s quality and the update’s lack of substance, the precise domain match was the major priority. The biggest flaw of EDM was that website SEOs would purchase domains with exact match keyword phrases, and set up a site, but have very little to no useful content on it. And performing it was quite simple. As a result of this modification, non-.com names were subjected to a harsher penalty than their.com counterparts.
