That is why whenever you come to Google Search to find relevant and useful\ninformation, it is our ongoing commitment to make sure users receive the highest quality results\npossible.\n\n\nUnfortunately, on the web there are some disruptive behaviors and content that we call \"webspam\"\nthat can degrade the experience for people coming to find helpful information. We have a number\nof teams who work to prevent webspam from appearing in your search results, and it's a constant\nchallenge to stay ahead of the spammers. At the same time, we continue to engage with webmasters\nto ensure they're following best practices and can find success on Search, making great content\navailable on the open web.\n\n\nLooking back at last year, here's a snapshot of how we fought spam on Search in 2019, and how we\nsupported the webmaster community.\n\nFighting Spam at Scale\n----------------------\n\n\nWith hundreds of billions of webpages in our index serving billions of queries every day,\nperhaps it's not too surprising that there continue to be bad actors who try to manipulate\nsearch ranking. In fact, we observed that **more than 25 Billion pages we discover each\nday are spammy**. That's a lot of spam and it goes to show the scale, persistence, and\nthe lengths that spammers are willing to go. We're very serious about making sure that your\nchance of encountering spammy pages in Search is as small as possible. Our efforts have helped\nensure that more than 99% of visits from our results lead to experiences without spam.\n\nUpdates from last year\n----------------------\n\n\nIn 2018, we reported that we had reduced\n[user-generated spam](/search/docs/advanced/guidelines/user-gen-spam) by 80%,\nand we're happy to confirm that this type of abuse did not grow in 2019. Link spam continued to\nbe a popular form of spam, but our team was successful in containing its impact in 2019. More\nthan 90% of link spam was caught by our systems, and techniques such as paid links or link\nexchange have been made less effective.\n\n\nHacked spam, while still a commonly observed challenge, has been more stable compared to\nprevious years. We continued to work on solutions to better detect and notify affected\nwebmasters and platforms and\n[help them recover from hacked websites](/web/fundamentals/security/hacked).\n\nSpam Trends\n-----------\n\n\nOne of our top priorities in 2019 was improving our spam fighting capabilities through machine\nlearning systems. Our machine learning solutions, combined with our proven and time-tested\nmanual enforcement capability, have been instrumental in identifying and preventing spammy\nresults from being served to users.\n\n\nIn the last few years, we've observed an increase in spammy sites with\n[auto-generated](/search/docs/advanced/guidelines/auto-gen-content) and\n[scraped content](/search/docs/advanced/guidelines/scraped-content)\nwith behaviors that annoy or harm searchers, such as fake buttons, overwhelming ads, suspicious\nredirects and malware. These websites are often deceptive and offer no real value to people. In\n2019, we were able to reduce the impact on Search users from this type of spam by more than 60%\ncompared to 2018.\n\n\nAs we improve our capability and efficiency in catching spam, we're continuously investing in\nreducing broader types of harm, like scams and fraud. These sites trick people into thinking\nthey're visiting an official or authoritative site and in many cases, people can end up\ndisclosing sensitive personal information, losing money, or infecting their devices with\nmalware. We have been paying close attention to queries that are prone to scam and fraud and\nwe've worked to stay ahead of spam tactics in those spaces to protect users.\n\nWorking with webmasters and developers for a better web\n-------------------------------------------------------\n\n\nMuch of the work we do to fight against spam is using automated systems to detect spammy\nbehavior, but those systems aren't perfect and can't catch everything. As someone who uses\nSearch, you can also help us fight spam and other issues by\n[reporting spam on search](/search/docs/advanced/guidelines/report-spam),\n[phishing](https://safebrowsing.google.com/safebrowsing/report_phish/) or\n[malware](https://www.google.com/safebrowsing/report_badware/). We received nearly\n230,000 reports of search spam in 2019, and we were able to take action on 82% of those reports\nwe processed. We appreciate all the reports you sent to us and your help in keeping search\nresults clean!\n\n\nSo what do we do when we get those reports or identify that something isn't quite right? An\nimportant part of what we do is notifying webmasters when we detect something wrong with their\nwebsite. In 2019, we generated more than 90 million messages to website owners to let them know\nabout issues, problems that may affect their site's appearance on Search results and potential\nimprovements that can be implemented. Of all messages, about 4.3 million were related to\n[manual actions](https://support.google.com/webmasters/answer/9044175), resulting\nfrom violations of our Webmaster Guidelines.\n\n\nAnd we're always looking for ways to better help site owners. There were many initiatives in\n2019 aimed at improving communications, such as\n[the new Search Console messages](/search/blog/2019/12/search-console-messages),\n[Site Kit for WordPress sites](/search/blog/2019/10/site-kit-is-now-available-for-all)\nor\n[the Auto-DNS verification in the new Search Console](/search/blog/2019/09/auto-dns-verification).\nWe hope that these initiatives have equipped webmasters with more convenient ways to get their\nsites verified and will continue to be helpful. We also hope this provides quicker access to\nnews and that webmasters will be able to fix webspam issues or hack issues more effectively and\nefficiently.\n\n\nWhile we deeply focused on cleaning up spam, we also didn't forget to keep up with the evolution\nof the web and\n[rethought how we wanted to\ntreat `\"nofollow\"` links](/search/blog/2019/09/evolving-nofollow-new-ways-to-identify). Originally introduced as a means to\nhelp fight comment spam and annotate sponsored links, the `\"nofollow\"`\nattribute has come a long way. But we're not stopping there. We believe it's time for it to\nevolve even more, just as how our spam fighting capability has evolved. We introduced two new\nlink attributes, `rel=\"sponsored\"` and `rel=\"ugc\"`,\nthat provide webmasters with additional ways to identify to Google Search the nature of\nparticular links. Along with `rel=\"nofollow\"`, we began treating these\nas hints for us to incorporate for ranking purposes. We are very excited to see that these new\nrel attributes were well received and adopted by webmasters around the world!\n\nEngaging with the community\n---------------------------\n\n\nAs always, we're grateful for all the opportunities we had last year to connect with webmasters\naround the world, helping them improve their presence in Search and hearing feedback. We\ndelivered more than 150 online office hours, online events and offline events in many cities\nacross the globe to a wide range of audience including SEOs, developers, online marketers and\nbusiness owners. Among those events, we have been delighted by\n[the momentum behind our Webmaster Conferences](/search/blog/2019/09/join-us-at-webmaster-conference-in)\nin 35 locations across 15 countries and 12 languages around the world, including the first\nProduct Summit version in Mountain View. While we're not currently able to host in-person\nevents, we look forward to more of these\n[events](/search/events) and virtual\ntouchpoints in the future.\n\n\nWebmasters continued to find solutions and tips on our\n[Webmasters Help Community](https://support.google.com/webmasters/community)\nwith more than 30,000 threads in 2019 in more than a dozen languages. On YouTube, we\n[launched #AskGoogleWebmasters](/search/blog/2019/08/you-askgooglewebmasters-we-answer)\nas well as series such as\n[SEO mythbusting](/search/blog/2019/06/a-new-series-on-seo-for-web-developers) to\nensure that your questions get answered and your uncertainties get clarified.\n\n\nWe know that our journey to better web with you is ongoing and we would love to continue this\nwith you in the year to come!
