为什么要做谷歌推广赚钱？谷歌如何收录出海独立站
随着经济环境变化，企业出海变成了不可逃避的话题，随之而来的独立站运营也就显得尤为重要。下面我们来分析全球最大搜索引擎谷歌如何收录你的独立站，并且呈现给全球客户。知其所以然，你才能更好地进行搜索引擎优化，打造"赚钱的核动力机器"。
With the changing economic environment, going global has become an unavoidable topic for enterprises, making independent website operation particularly important. Below we'll analyze how Google, the world's largest search engine, indexes your independent website and presents it to global customers. Only by understanding the principles can you better optimize for search engines and create a "money-making nuclear engine".
抓取 Crawling
其实谷歌理解你的网页没有多神秘，就和你自己看网页是一样的。他通过一个叫做爬虫的脚本，使用get方法获取到你的网页。对比理解就是你打开了网页，然后切记，他会通过代码获取你的html源代码。
There's nothing mysterious about how Google understands your webpage - it's similar to how you view webpages. Google uses a script called a crawler to fetch your webpage using the GET method. To understand by analogy: it's like you opening a webpage, but remember, it gets your HTML source code.
大坑 Warning: 如果你是前端渲染（比如vue、react），因为它们是通过js渲染出页面内容，简单说html代码是空的，所以搜索引擎什么内容都抓不到，也就谈不上收录和排名了。
Warning: If you use front-end rendering (like Vue or React), since they render page content through JavaScript, meaning the HTML code is essentially empty, search engines can't capture any content, let alone indexing and ranking.
解析 Parsing
获取到html代码后，谷歌内部进行数据解析，提取到正文、页头、页尾、Meta等数据。切记，页面上所有链接都会被提取出来。
After obtaining the HTML code, Google internally parses the data, extracting content, headers, footers, meta data, etc. Remember, all links on the page will be extracted.
索引 Indexing
将解析出来的数据进行分词、抽取主题、建立正反索引。这一步就是通过页面信息理解你的网页是做什么的，并且根据解析出的内容进行打分。
The parsed data undergoes word segmentation, topic extraction, and forward/reverse indexing. This step helps Google understand what your webpage is about through page information and scores it based on the parsed content.
链接处理 Link Processing
遍历抓取链接，判断是否为爬取过链接。如果没有爬取过的放入待爬列表，进入待爬列表中链接，重复上面操作。通过这种方式，爬虫就建立了关于你的网站所有涉及的链接的关系网。
It traverses captured links to determine if they've been crawled before. Uncrawled links are added to a to-crawl list, and the process repeats. This way, the crawler builds a relational network of all links related to your website.
小技巧 Tip: 想让谷歌快速收录你，去谷歌爬虫频繁爬取的地方发送你的外链，是常用手段。
Tip: To get Google to index you quickly, a common method is to place your external links where Google crawlers frequently visit.
内链与外链 Internal & External Links
内链是站内链接的简称，是指向当前网站其它页面的链接。外链是站外链接的简称，又名出站链接，是指向别的网站的链接。
Internal links refer to links pointing to other pages within the same website. External links, also called outbound links, point to other websites.
Sitemap
简单来说，为了表示你对爬虫的欢迎，和方便爬虫快速收录你，就不麻烦他老人家自己一个个去爬了，你写好了一个你自己网站的所有链接的列表，让他只关注这一个文件就快速爬取完。
Simply put, to show welcome to crawlers and facilitate quick indexing, instead of making them crawl each page individually, you provide a sitemap - a list of all your website's links - allowing them to focus on this single file for quick crawling.
注意 Note: 当然，这个是你的好意，谷歌不一定这么做，或者全这么做，他可能只是自己去爬取所有链接。
Note: Of course, this is your goodwill - Google may not necessarily do this completely, and might still crawl all links independently.
页面深度 Page Depth
页面深度的意思就是从首页开始点击，要点击多少次才能看到最终的页面。市面上给的官方建议是不超过5层，但我们建议不超过3层，也就是你保证你的所有页面一定不要超过3次点击就一定能让人看到。
Page depth refers to how many clicks from the homepage are needed to reach the final page. The official recommendation is no more than 5 layers, but we suggest no more than 3 - ensuring all pages are reachable within 3 clicks.
权重传递 Weight Transfer
权重其实就是谷歌对你这个页面，这个网站的重视程度，程度越高，收录越好。这种重视，会在站内传递，也在网站间传递。
Weight essentially represents how much importance Google assigns to your page or website - higher importance leads to better indexing. This importance transfers both within the site and between websites.
一般站内链接都是 do follow 的，也就是会完全传递权重，而外链则为了不传递太多权重出去，我们会设置为 no follow。谷歌有自己的一套复杂的算法，会综合各种情况去计算每一个链接能够传递的权重到底是多少。
Typically, internal links are "dofollow", meaning they fully transfer weight, while external links are often set as "nofollow" to avoid transferring too much weight. Google has its own complex algorithm that considers various factors to calculate exactly how much weight each link can transfer.
