seo外链重要性
No one likes to wait for a site to load. I don’t. You don’t. And search engines really don’t.
没有人喜欢等待网站加载。 我不。 你不知道 搜索引擎确实没有。
While UX, keyword density, and site structure (among other things) dominate SEO and ranking-related conversations, site speed should play a more prominent role.
尽管用户体验，关键字密度和网站结构(除其他因素外)主导着SEO和与排名相关的对话，但网站速度应扮演更重要的角色。
I have been working to building WFHAdviser.com and have learned valuable lessons about site speed along the way.
我一直在努力构建WFHAdviser.com，并在此过程中获得了有关网站速度的宝贵经验。
I want to pass these lessons on to you.
我想把这些教训传给你。
Everyone knows that site speed has a place in SEO talk.
每个人都知道网站速度在SEO讨论中占有一席之地。
But, did you know that in 2018 Google published a site speed-specific change to their algorithm? Called “the speed update,” the changes made a mobile site’s speed play a more prominent role in search as well as ads.
但是，您是否知道Google在2018年发布了针对其算法的网站速度特定更改？ 这种变化称为“速度更新”，这些变化使移动网站的速度在搜索和广告中扮演着更加重要的角色。
The update was necessary as well. At the time of its release, Google’s research showed that the chances of bounce increased 32% if site load time went up from one second to three seconds.
更新也是必要的。 在发布时，Google的研究表明，如果网站加载时间从一秒增加到三秒，则跳回的可能性会增加32％。
Bounce rate chances also increased to 90% if it went up to five seconds and 123% at 10 seconds or more.
如果跳动速率提高到5秒，则跳动几率也提高到90％，而在10秒或更长的时间内跳动率提高到123％。
The change certainly had a positive impact on the online user experience. User-centric performance metrics improved by 15% to 20%, and cart abandonment went down by 20% within a few months after the update was released.
这一变化无疑对在线用户体验产生了积极影响。 在发布更新后的几个月内，以用户为中心的性能指标提高了15％至20％，购物车放弃率下降了20％。
So, what does it all mean?
那么，这到底意味着什么呢？
Essentially: those with well-optimized pages will rank higher in search engines for their target keywords.
本质上：页面优化程度高的用户将在搜索引擎中为其目标关键字排名更高。
Conduct a keyword gap analysis, a process defined by Loganix as "identifying valuable keywords that your competitors rank well for, but you do not.”
进行关键字差距分析 ，这是Loganix定义的过程，“确定竞争对手认为您有价值的有价值的关键字，但您却没有。”
When you find valuable keywords your competitors do not rank for, focus heavily on optimizing these pages for speed to increase the gap even further.
当您发现竞争对手无法获得的有价值的关键字时，请集中精力优化这些页面以提高速度，从而进一步扩大差距。
The importance of site speed goes beyond rankings alone. Google conducted a thorough review of mobile site speed’s impact on consumer willingness to spend.
网站速度的重要性已不仅仅是排名。 Google对移动网站速度对消费者消费意愿的影响进行了彻底的审查。
Their report, called Milliseconds Make Millions, showed a massive ripple effect down the buyer journey from even a 0.1 second change in load time.
他们的报告称为“ 毫秒赚百万美元” ，显示了巨大的连锁React，即使加载时间仅变化了0.1秒，也对买家的旅程产生了巨大的影响。
For example, a 0.1% decrease in a retail site’s load time caused a 9.2% increase in online spending.
例如，零售网站的加载时间减少了0.1％，导致在线支出增加了9.2％。
For luxury brands, a similar increase in performance led to a 40% increase in site browsing and items being added to the cart.
对于奢侈品牌来说，类似的性能提升导致网站浏览和购物车中添加的物品数量增加了40％。
Similar studies have found the same relationship between consumer activity and site load times. Google has said that two seconds is the ideal maximum site load time for an e-commerce site.
相似的研究发现，消费者活动与站点加载时间之间存在相同的关系。 Google表示，两秒是电子商务网站的理想最大网站加载时间。
So, we have established that Google loves a fast loading site, as do users. And yet most webmasters aren’t really paying attention.
因此，我们已经确定Google和用户一样都喜欢快速加载的网站。 但是大多数网站管理员并没有真正注意。
You should.
你应该。
A survey of 5.2 million mobile and desktop website pages found that most site load times were woefully inadequate.
一项针对520万个移动和桌面网站页面的调查发现，大多数网站加载时间严重不足。
For example, the average load time for a desktop page in this study was 10.3 seconds, while that of a mobile webpage was 27.3 seconds.
例如，在此研究中，桌面页面的平均加载时间为10.3秒，而移动网页的平均加载时间为27.3秒。
The average web page also takes 87.4% longer to load on mobile than desktop.
移动设备上的平均网页加载时间也比台式机长87.4％。
This is a huge opportunity for anyone who’s reading this. You can easily out-flank your competition simply by improving your site speed.
对于任何正在阅读本文的人来说，这都是一个巨大的机会。 您只需提高网站速度，即可轻松超越竞争对手。
Not only will doing so increase your SERP presence, but it can bring down your bounce rate while increasing traffic too.
这样做不仅会增加您的SERP占有率，而且会降低跳出率，同时也会增加流量。
Reducing your site load time isn’t really all that difficult either. Here are three ways to do just that.
减少站点加载时间也不是那么困难。 做到这一点的三种方法。
A website consists of various HTML, JavaScript, and CSS files which dictate how it will appear and function. These files also take up a lot of space, especially if they are coded inefficiently.
网站由各种HTML，JavaScript和CSS文件组成，这些文件决定了网站的外观和功能。 这些文件也占用大量空间，尤其是在编码效率低下的情况下。
The first step here will be to reduce the number of requests your website files are causing.
第一步是减少您的网站文件引起的请求数量。
An HTTP request is generated by each on-page element. The more elements your site has, the more requests it generates. Alas, this leads to slower site loads.
每个页面元素都会生成一个HTTP请求。 您的网站包含的元素越多，它生成的请求就越多。 las，这导致站点负载变慢。
You can use Google Chrome’s Network Panel to find the number of HTTP requests a page is generating. Make a note of unnecessary requests and take them out.
您可以使用Google Chrome浏览器的“ 网络面板”来查找页面正在生成的HTTP请求数。 记录不必要的请求并将其取出。
An easier way here will be to simply combine similar HTML, JavaScript, and CSS files. So, instead of having multiple HTML files, copy all the code into one file.
这里更简单的方法是简单地组合类似HTML，JavaScript和CSS文件。 因此，不要有多个HTML文件，而是将所有代码复制到一个文件中。
Repeat for JavaScript and CSS. Fewer files will generate fewer HTTP requests, thereby decreasing your site load time.
对JavaScript和CSS重复上述步骤。 更少的文件将生成更少的HTTP请求，从而减少您的网站加载时间。
Minifying your site code will also greatly help. Look for removable pieces of code, line breaks, and whitespace in your website’s files. While minification can be done manually, there are tools available as well:
最小化您的站点代码也将大有帮助。 在网站文件中查找可移动的代码段，换行符和空格。 虽然可以手动进行缩小，但也提供了一些工具：
If you have interactive elements of your website, these can often slow things down.
如果您的网站具有交互式元素，则这些元素通常会使速度变慢。
What is defined as interactive? Well, here is a great example from Preply:
什么是交互式？ 好吧，这是Preply的一个很好的例子：
Each time you click on the world map, it pulls more information.
每次您单击世界地图时，它都会提取更多信息。
If not correctly optimized and cached, this can slow load times dramatically.
如果未正确优化和缓存，则会大大降低加载时间。
Work with a developer to ensure your code is minimal and efficient.
与开发人员合作，以确保您的代码最少且高效。
While images are essential to a good online experience, they can quickly eat into your site load time. This is especially true for e-commerce sites that use a lot of images, like Sleep Junkie, pictured here.
图片对于获得良好的在线体验至关重要，但它们会很快占用您的网站加载时间。 对于使用大量图像的电子商务站点尤其如此，如上图所示的Sleep Junkie 。
Even though most web pages weigh in at a hefty 2 MB these days, Google recommends keeping them under 500 KB. Of course this presents a challenge since images are usually the heaviest on-page component.
即使这些天大多数网页的重量都很大，只有2 MB，但Google建议您将其保持在500 KB以下。 当然，这提出了挑战，因为图像通常是页面上最重的成分。
Compressing images is also a fine balancing act, since it reduces image quality. The best place to start will be selecting an appropriate image format.
压缩图像也是一种很好的平衡方法，因为它会降低图像质量。 最好的起点是选择适当的图像格式。
There are several ways you can use high quality images without adding to your site’s load time. A Content Delivery Network like AWS Cloudfront can be used to offload your images which can be served on demand.
您可以通过多种方式使用高质量的图像，而不会增加网站的加载时间。 诸如AWS Cloudfront之类的内容交付网络可用于卸载可按需提供的图像。
Secondly, you can also set up your CMS to scale images site-wide. This way you can create a template for thumbnail images and how their full versions are displayed.
其次，您还可以设置CMS以在整个站点范围内缩放图像。 这样，您可以为缩略图图像及其完整版本的显示方式创建模板。
If you use WordPress, consider using the Imsanity plugin to setup image compression.
如果您使用WordPress，请考虑使用Imsanity插件来设置图像压缩。
Alternatively, you can also use free web-based image compressors like Jpeg-Optimizer, Optimizilla, and Kraken to manually compress your site images.
另外，您还可以使用免费的基于Web的图像压缩器(例如Jpeg-Optimizer，Optimizeilla和Kraken)来手动压缩站点图像。
Videos are usually the single biggest files your website can have. I have a few on WFHAdviser.com/videos that are hosted on YouTube.
视频通常是您的网站可以拥有的最大文件。 我在WFHAdviser.com/videos上有一些YouTube托管的视频。
So, even if you do keep the number of videos down, even a single file can slow down load time considerably. Like images, however, you have several options to compress video files to manageable limits.
因此，即使您确实减少了视频的数量，即使是单个文件也会大大降低加载时间。 但是，像图像一样，您有多种选择可将视频文件压缩到可管理的限制。
Video size optimization begins right at production. Here’s an awesome example of video publishing done right. Even though the page has a video embedded, it loads fairly quickly.
视频尺寸优化从生产开始。 这是一个很好的视频发布示例。 即使页面上嵌入了视频，它的加载速度也相当快。
It’s also best to move to an HTML5 video format like MP4 or WebM. Both are supported by most browsers and allow for acceptable compression-quality ratios.
最好也转换为HTML5视频格式，例如MP4或WebM。 大多数浏览器都支持这两种格式，并允许可接受的压缩质量比。
You can use a video compression tool like Handbrake to reduce your video file sizes without sacrificing (much) quality too. Also, consider removing audio from videos that are muted.
您可以使用“手刹”之类的视频压缩工具来减少视频文件的大小，而不会牺牲(很多)质量。 另外，请考虑从静音的视频中删除音频。
A CDN can again be used to serve videos on demand here. While auto playing videos are best avoided, they should be set to play once the webpage has loaded completely.
这里可以再次使用CDN来按需提供视频。 虽然最好避免自动播放视频，但应将其设置为在网页完全加载后开始播放。
Alternatively, you can simply embed your videos using a video streaming service like YouTube or Wistia, as in this example on the Manly Wellness site:
另外，您可以使用YouTube或Wistia之类的视频流服务简单地嵌入视频，如在Manly Wellness网站上的以下示例所示：
This allows your site to send small chunks of content to the user, speeding up load times.
这使您的站点可以向用户发送少量内容，从而加快加载时间。
Site load times are only going to become more important moving forward.
站点加载时间只会变得越来越重要。
Embed that learning into your technical learnings today. Change how you design and build.
将这些知识融入您今天的技术学习中。 改变您的设计和建造方式。
It’s best to make these learnings an integral part of your digital strategy.
最好将这些学习内容纳入您的数字策略中。
Alternatively, you can have a SEO agency take care of it for you. Since image optimization is part of SEO, a targeted campaign can help you create a properly formatted site right from the get go.
另外，您可以让SEO代理机构为您处理。 由于图像优化是SEO的一部分，因此有针对性的广告系列可以帮助您从一开始就创建格式正确的网站。
The choice is yours and your users – like Search Engines – will reward this attention to detail.
选择权由您决定，您的用户(如搜索引擎)将获得对细节的关注。
