- 3. What is Google Algorithm? ■ Google Algorithm is a set of code or system which is particularly used to retrieve data form its search index & provides best possible results for queries. ■ In other words, it is a series of algorithm that analyzes what you have searched or looking for and what information to return you.
- 4. ■ Google Algo searches web pages that contain the keywords you used to search, then assigning a rank to each page based several factors, including how many times the keywords appear on the page. ■ The best links relating to your search query are theoretically the first ones Google lists.
- 5. Google Search Algorithm can be broken into 5 major parts: ■ Word Analyzing : Google strives to understand what you are searching for to provide you better results. For example, our synonym system helps Search know what you mean, even if a word has multiple definitions. ■ Search Match : Google looks for webpages that match your query. It does this by looking up your terms in the index & searching for websites that most closely match the information you require. This is done by analyzing details such as whether the keyword appears in titles or headings and how often it appears on a page. ■ Ranking Pages : When searching for a typical query, there to be tens of millions of websites with relevant information. So, to ensure that Google provides the best results, its algorithms get to work. ■ Context Matters : Not everyone is served with the same search results, even if they search for the same keywords. A variety of factors –past search history, search settings, & location – all come into play when generating results. ■ Returns to Best Result : Before you are served any results (which is done almost instantaneously), Google evaluates the search terms as to provide the most helpful information.
- 7. Major Google Algorithms Panda : Duplicate, plagiarized or thin content; user-generated spam; keyword stuffing Penguin : Spammy or irrelevant links; links with over-optimized anchor text, to down-rank sites whose links it deems manipulative. Hummingbird : Keyword stuffing; low-quality content. Helps Google better interpret search queries and provide results that match searcher intent. Pigeon : Poor on- and off-page SEO. Affects those searches in which the user’s location plays an important part. Mobile : Lack of a mobile version of the page; poor mobile usability. Ensures that mobile-friendly pages rank at the top of mobile search. RankBrain : Lack of query-specific relevance features; shallow content; poor UX Fred : Thin, affiliate-heavy or ad-centered content. Fred targets websites that violate Google’s webmaster guidelines.
- 8. 2015 Updates ■ RankBrain* — October 26, 2015 Google made a major announcement, revealing that machine learning had been a part of algorithm for months, query specific relevant features. Machine-learning artificial intelligence system helps Google process some of its search results, in particular rare or one-of-a-kind queries. ■ Panda 4.2 (#28) — July 17, 2015 Focused on spammy links & low quality content to provide relevant & high quality content. ■ The Quality Update — May 3, 2015 Google acknowledged a core algorithm change impacting "quality signals" in terms of how it processes quality signals.
- 9. Mobile Update AKA "Mobilegeddon" — April 22, 2015 Google pre-announced an algorithm update, telling us that mobile rankings would differ for mobile-friendly sites starting on April 21st. The impact of this update was, in the short-term, much smaller than expected, and our data showed that algorithm flux peaked on April 22nd.
- 10. 2016 Updates ■ Penguin 4.0, Phase 1 — September 27, 2016 Penguin algorithm, penalizing bad links instead of penalizing sites for high quality backlinks. ■ Penguin 4.0 Announcement — September 23, 2016 After almost 2 years of waiting, Google finally announced a major Penguin update. They suggested the new Penguin is now real-time and baked into the "core" algorithm. Initial impact assessments were small, but it was later revealed that the Penguin 4.0 rollout was unusually long and multi-phase. ■ Mobile-friendly 2 — May 12, 2016 Just more than a year after the original "mobile friendly" update, Google rolled out another ranking signal boost to benefit mobile-friendly sites on mobile search. Since the majority of sites we track are already mobile-friendly, it's likely the impact of the latest update was small.
- 11. 2017 Updates ■ Intrusive Interstitial Penalty — January 10, 2017 Penalty to punish pop-ups that might damage the mobile user experience. ■ Fred Update — March 9, 2017 Thin, affiliate-heavy or ad-centered content. Fred targeted content sites having large amount of Ads, which were created to generate revenue only instead of resolving user problems. ■ Google Jobs — June 20, 2017 Google officially launched their jobs portal, including a stand-alone 3- pack of job listings in search results. These results drew data from almost all of the major providers, including LinkedIn, Monster, Glassdoor, and CareerBuilder.
- 12. ■ Chrome Security Warnings (Forms) — October 17, 2017 Not an algorithm update, this was an important step in Google's push toward HTTPS and may have a material impact on site traffic. ■ Snippet Length Increase — November 30, 2017 Google increased them across a large no. of results. This led us to adopt a new Meta Description limit -- up to 300 characters from the previous 155 (almost doubling).
- 13. 2018 Updates ■ "Brackets" Core Update — March 8, 2018 Focused heavily on content quality, which we know is an important factor for Google. Main impact of this update is how it impacts which sites are appearing in the rich snippets. Rich snippets are known for having a higher click-through with more quality information. ■ Zero-result SERP Test — March 14, 2018 Including some time/date queries and unit conversion calculators, Google started displaying zero organic results and a "Show all results" button. ■ Mobile-First Index Roll-out — March 26, 2018 The mobile version of your website becomes the starting point for what Google includes in their index. It’s not a mobile-only index: for instance, if a site doesn’t have a mobile-friendly version, the desktop site can still be included in the index.
- 14. ■ Snippet Length Drop — May 13, 2018 After testing longer display snippets of up to 300+ characters for a few months, Google rolled back most snippets to the former limit (about 150-160 characters). ■ Video Carousels — June 14, 2018 Google moved videos from organic-like results with thumbnails into a dedicated video carousel, causing a shake-up in results that were previously tracked as organic. ■ Mobile Speed Update — July 9, 2018 Mobile page speed update, making page speed a ranking factor for mobile results. Google claimed that this only affected the slowest mobile sites, and there was no evidence of major mobile rankings shifts. ■ "Medic" Core Update — August 1, 2018 Google confirmed a "broad core algorithm update," with wide reports of massive impact. It rolled out over the period of about a week, but peaked on August 1-2. This update seemed to disproportionately affect sites in the health and wellness vertical, although large-scale impact was seen in all verticals.
- 15. 2019 Updates ■ March 2019 Core Update — March 12, 2019 Google confirmed a "core" update, stating it was the third major core update since they began using that label. MozCast hit a peak of 101.2°F, a bit below March 1st temperatures. No specific details were given about the nature of the update. ■ Deindexing Bug — April 5, 2019 Google confirmed a bug that dropped pages from the search index around the weekend of April 5th. Moz data suggested drops on April 5th and 7th, with about 4% of stable URLs falling off of page one. Most sites recovered soon after. ■ Indexing Bugs — May 23, 2019 The first bug reportedly was preventing new content from being properly indexed. MozCast confirmed unusually high SERP flux from May 23-25.
- 16. ■ June 2019 Core Update — June 3, 2019 Google pre-announced a "core" update, but with limited details. Sites impacted in previous core updates seem to have been affected, in some cases, and some major UK publishers reported heavy losses. On average, the impact was smaller than the August "Medic" update, as measured by MozCast. ■ Site Diversity Update — June 6, 2019 Google pre-announced a "site diversity" update, claiming it would improve situations where sites had more than two organic listings. Moz data showed that, while the update did marginally improve SERPs with 3-5 duplicate sites on page one, the impact was relatively small.
