|Baden – Baden
|The Baden Baden update was focused on making it harder for websites with over-optimized, keyword-stuffed texts to rank for competitive keywords, thus allowing better quality results to shine through.
Korolyov works to improve the foundations of Palekh algorithm update, analysing more potential search results in a much more comprehensive fashion, in real-time, a lot faster.
|Palekh was designed to improve how the core algorithm understood and interpreted long-tail search queries. Using a series of neural networks, it worked to understand semantics and establish dominant and common interpretations of a long tail query to return search results that were relevant, even if the search terms themselves weren’t physically present in the content.
|Vladivostok changed Yandex’s core algorithm and how websites and content cater for the mobile user and mobile experience.
|Minusinsk is a link-based algorithm update that required that Webmasters should stop using link spam and other manipulative methods to influence search results.
|AGC Filter update focused on websites selling and placing links.
|Search Result Manipulation
|Russian link networks performed a “link strengthening” service, which was becoming a real problem.
They would manipulate search results user data by excessively clicking on client results, or websites within their network linking to client websites under the premise it would improve the performance of the client site, directly and indirectly.
|AGS 40 update targeted websites that were built to drive affiliate link clicks or advertising revenues through impressions.
|The algorithm update took into account a user’s search history and behaviors on search results pages.
|Reykjavik update search results are based on a user’s browser language and search language preference, it can be argued that this was Yandex’s first step towards user-level SERP personalisation.
|The update further improved the algorithm’s ability to detect which region a website was based in, even if the webmaster had neglected to indicate a region in Yandex.Webmaster. The Obninsk algorithm also had a negative impact on websites using low-quality link spam.
|2010 saw the introduction of Spectrum in an event known as the Krasnodar update. Spectrum divides queries into 60 different semantic categories and then calculates the weightings and proportions in which the answers should be presented to the user, diversifying the top ten search results.
|April, June & August 2009
|The update enabled users to manually determine if they only saw results from their own region, where Arzamas made this decision automatically based on whether or not the query needed local or national results.
|AGS was a penalty, and if you were hit by it Yandex only showed one to ten pages of your whole website within its search results (this was changed in 2014 so that there were no more page restrictions).
|Version 2.0 of Magadan took into account the uniqueness of content, and the search engine began to understand the difference between commercial/non-commercial and local/national queries.
|Magadan also came with a “test version”, and webmasters could visit the now-defunct buki.yandex.ru, test the search results, and leave feedback for the Yandex search team.
|Nakhodka update targeted promoted websites’ internal pages within search results, rather than just the homepage. Nakhodka also aimed to tackle the issue of cloaking much more aggressively.
|8 SP1 (Yandex algorithm)
|8 SP1 introduced “Trust Rank” to determine to credibility (not age) of the website as a ranking factor. This also took some of the weighting off backlinks as a factor.
|Unnamed 2007 Update
|Yandex began introducing new ranking and factor weighting formulas for single, and multi-word queries. It also marked the start of Yandex search team support.
|Arzamas enabled users to manually determine if they only saw results from their own region, where Arzamas made this decision automatically based on whether or not the query needed local or national results.
|Nepot Filter (unofficial name)
|The update was Yandex’s first venture into controlling link spam. Rather than link quality, this filter imposed a penalty on the links themselves and specifically sought out websites that acquired big volumes of unnatural links in short spaces of time.
