Google では全力を尽くして、競合相手が他のサイトの掲載順位に悪影響を与えることを阻止しています。ご自身のサイトにリンクしている別のサイトに疑念を持たれた場合は、ウェブサイトの所有者に問い合わせることをおすすめします。Google はウェブ上に公開されている情報を収集し整理していますが、収集するページのコンテンツを管理しているわけではありません。
どのような手口で検索結果を操作しようとすると、手動によるスパム対策がサイトに適用されますか?
Google の目標は、ユーザーのクエリに対して、関連性の高い最適な結果を提供することです。
サイト所有者は、偶然または故意に、検索結果を操作しようとする手口を使用する場合があります。たとえば、サイトに隠しテキストや隠しリンクを追加したり、クローキングや不正なリダイレクトを使用したりする場合があります。手動による対策の適用を招く可能性がある不正行為については、スパムに関するポリシーで説明されています。
サイトが Google のスパムに関するポリシーに違反していた点を修正しました。現在はサイトがガイドラインを遵守していることを Google に知らせるにはどうすればよいですか?

Google is very good at detecting unnatural\nlinks that violate our [spam policies](/search/docs/essentials/spam-policies)\n(for example, those that come from link-exchange schemes, paid links\nschemes, or are auto-generated), so participating in such schemes could end up doing\nmore harm than good.\n\nWatch this video for some ideas about getting people to link to your site: \n\nMy site used to rank really well, but now it doesn't. What happened?\n--------------------------------------------------------------------\n\nThe web is an organic, constantly shifting ecosystem, and your site's performance in\nGoogle Search can change for many reasons. To start troubleshooting, check out\n[Why\nis my page missing from Google Search](https://support.google.com/webmasters/answer/7474347).\n\nDoes my top-level domain (TLD; for example, .com, .org, .gov, .ponies) impact my site's\nperformance in Google Search?\n---------------------------------------------------------------------------------------------------------------------\n\nNo. Google's goal is to return the best and most relevant results to people,\nregardless of the top-level domain. If our system determines that the best result is\na page on a new Generic Top Level Domain (gTLD), we'll return that page in search\nresults.\n\nCan a competitor do anything to damage my site's performance in search results?\n-------------------------------------------------------------------------------\n\nWe work really hard to make sure that competitors can't negatively affect other\nsites' rankings. If you're concerned about another site linking to yours, we suggest\n[contacting the owner of the website](https://support.google.com/websearch/troubleshooter/3111061). Google aggregates and organizes information published\non the web; we don't control the content of these pages.\n\nWhat techniques might cause Google to place a manual spam action on my site in search results?\n----------------------------------------------------------------------------------------------\n\nOur goal is to provide users with the best and most relevant results for their query.\nSometimes site owners---accidentally or on purpose---use techniques that attempt to game\nthe system. For example, a site might include hidden text or links, or use cloaking\nor sneaky redirects. Our [spam policies](/search/docs/essentials/spam-policies)\noutline the illicit practices which can lead to a manual action.\n\nI made some changes so that my site is no longer in violation of Google's\nspam policies. How can I make sure Google knows that my site is clean?\n------------------------------------------------------------------------------------------------------------------------------------------------\n\nSubmit a [reconsideration request](https://support.google.com/webmasters/answer/35843)\nand allow several weeks for the reconsideration process.\n\nWhy don't my images appear in Google Images?\n--------------------------------------------\n\nYou can improve how your images perform on Google Images by following the\n[Google Images best practices](/search/docs/appearance/google-images).\n\nWhy don't my videos appear in Google Search?\n--------------------------------------------\n\nYou can help us find and index your video content by following the\n[Video best practices](/search/docs/appearance/video).\n\nDoes buying ads improve my search ranking?\n------------------------------------------\n\nNo. Google's advertising programs are independent of our search results. Search\nresults display on the left side of our results page; ads appear on the right and in\nthe colored box at the top.\n\nParticipation in an advertising program doesn't positively or negatively affect\ninclusion or ranking in the Google search results. Inclusion and ranking in Google Search\nresults don't cost money; we don't accept payment to expedite inclusion or improve a site's ranking\nfor particular keywords.\n[Learn more about how Google ranks pages.](https://www.google.com/search/howsearchworks/mission/web-users/)"]]
