Search Engine Journal reports that the Google broad core algorithm has implemented a major update in the near future. These algorithms are designed to sink sites that do a lot of black hatting. Black hatting refers to security hacks that draw attention to the fact that the site has been hacked. In terms of search engine optimization, black hatting is more related to spurious attempts to increase a site's SERP with spam links and other techniques. Google's plans to update its broad core algorithms mean that sites with a lot of spam links could see a considerable decrease in their SERP. Overall, this means good news for sites that use quality links and do not overload their content with useless content just for the keywords and key phrases. In just a few days since its broad core algorithm update, sites have seen some shifting of their position in the SERPs as well as in their traffic levels. Site owners can track how this broad core algorithm update by Google affects their traffic by using Google Analytics. This tool shows a range of different activity types and levels over various time periods, such as one day, one week, one month or longer. The algorithm change was between July 31 and August 1, 2018, depending on the time zone of the site's server. Site owners can check how much traffic they got before and after the implementation of the algorithm changes. Some sites have seen up to a 20 percent decrease in organic search traffic. This is likely related to a site falling off of the first page of search results. A lower SERP means that the site probably moved from the first page to the second or third, perhaps even lower than that. Such a big drop is likely related to links that the algorithm has determined are spam-related or otherwise not relevant or from sites that also have a low rating. Site owners have also noticed a drop in total impressions. The drop of total impressions has not made much of a difference in the site's position on the SERPs.
