If you're anything like me, you probably read the title of this post and thought, "Latent semantic indexing ... wait, what is that?"

Latent semantic indexing (LSI, for short) can be an overwhelming and confusing term for anyone hearing it for the first time.

Luckily, although it sounds like something that requires a degree in computer science, it's actually a concept you're already probably familiar with — particularly if you have some basic knowledge of keywords and their close relationship with search engine optimization (SEO).

In this post, we'll define LSI and how the process can potentially benefit your overall SEO strategy, take a closer look at ways to find LSI-driven keywords, and outline how to add these keywords into your content.

让我们进去,对吧?

What is latent semantic indexing?

潜在语义Indexing, also known aslatent semantic analysis, is a mathematical practice that helps classify and retrieve information on particular key terms and concepts using singular value decomposition (SVD).

Through SVD, search engines are able to scan through unstructured data and identify any relationships between these terms and their context to better index these records for users online.

在SVD之前,计算机很难尝试掌握同义词或语义变化之间的差异。

为了帮助绘画图片,请以“愚蠢”和“弦”字样。当分开时,这些词代表了两个非常独立的定义,但是当汇集在一起​​时,它们的编队会创建一个崭新的概念:“愚蠢的字符串”。

If you work for an e-commerce company that sells silly string, you don't want your content arising for the word "silly" alone — in that case, you'd need to use LSI keywords to help let search engines know for which searches it should serve up your content.

随着技术的适应,由于相关性的模式更强,用户搜索的质量得到了高度提高。通过“茎”,计算机开始考虑一个单词可以在页面上代表的各种形式。

根据网站的内容,搜索引擎可以基于相关性(不使用思维阅读,而是使用LSI关键字)为结果提供结果。

搜索引擎使用LSI关键字来帮助将上下文添加到页面上,以提供更好的搜索结果。

As LSI became more sophisticated, the ability to group thematically came into place, which for many rank-driven content writers meant synonyms became your best friend.

So ... the more ranking LSI keywords, the better your overall position, right? Well, it depends.

What are LSI keywords?

LSI关键字基于这样的想法,即在整个内容中使用类似的关键字来增强主题或主题可以帮助提高整体SEO性能。

毕竟,如果您最终将一个关键字排名,那么您对相关关键字进行排名的可能性听起来很合理。

However, that isn't necessarily always the case. There is quite a bit of contradictory analysis challenging how much LSI真的boosts your content.

As Google and other search engines have become more sophisticated and advanced, we have learned there are many outside factors that influence overall ranking.

实际上,有noLSI是Google排名算法的一部分的想法背后的确定性。LSI是一种可以追溯到1980年代的练习,在当今时代,我们知道Google太聪明了,无法依靠同义词来检索和索引信息。

因此,“ LSI关键字”的力量受到质疑。但是,有些人认为,即使Google不使用LSI,只要它们没有被填充和自然使用,就不会添加同义词。

So what are a couple ways to help boost SEO that doesn't rely on LSI?

  1. Use structured data! There is nothing Google likes better and will reward more than data that users can understand. For more information on what structured data is and how to add it to your website check out theBeginner's Guide to Structured Data for Organizing & Optimizing Your Website.
  2. Practice co-occurrence, which relies on concept relativity, frequency in keyword occurrence, and closeness in keywords across different websites. Search engines will tend to use this method to scan and index websites most closely related. Therefore, if you're looking for a place to start, you should:
    • 确定您想排名的长尾关键字或短语
    • 研究顶级流行文章
    • 查找它们共同的概念或关键字
    • Incorporate and optimize on your findings!

Now, this doesn't mean LSI driven keywords are bad for SEO, it just means it shouldn't be your catch-all. In fact, there are a multitude of ways your content can benefit from LSI keywords. So let's dive a little deeper into how you can use LSI content to your advantage.

LSI驱动关键字研究的好处

搜索引擎不断寻找最relevant and thorough content for a given query. The internet is much like the universe, ever-expansive and well, big. That said, it’s not an easy task for even the best of search engines, like Google, to determine what a page’s content is really about.

更好的目标分类可以帮助发布者,营销人员和用户。例如,由于LSI驱动的内容是针对特定受众的,因此发布者可以提高参与度。在线用户互惠互利,因为他们正在搜索的查询更快,更准确地提供。

And, at the end of the day, users who find content that answer their questions are happy users, and happy users are more likely to engage or convert.

找到LSI关键字的5种方法

You're one step closer to becoming an LSI expert. Congrats! Now that you've learned a little bit on the importance of LSI keywords, let's walk through the various ways you can identify new keywords for upcoming blog posts and content.

1. A Simple Google Search

One of the easiest ways to find LSI keywords is Google itself. When you enter a term in the search query field, it automatically shows the keywords related to the particular query.

Let's use the earlier example of "silly string" again. An initial search of the word provides these results:

lsi-keyword-google-search

Again, there are a lot of pages this particular keyword could point to which is why we need to use LSI to add more context. If you continue to scroll down to the bottom, you'll find a section titled, "Searches related to" and your given query:

Use the list of keywords as a starting point for potential LSI keywords because it reveals what Google already associates with your primary keywords.

The best part? This method is 100% free!

2. Use the Keyword Planner Tool via Google AdWords

If you have access to Google AdWords, you can also use theirKeyword Planner tool.

Again, we'll use the "silly string" example. Begin by adding the term into the initial query box. Click "Get ideas" and you'll be redirected to a page that offers related keywords and an idea of how competitive search rankings are for said term.

3. Take Advantage of SERP Stat's Keyword Research Database Tool

您使用的另一个免费工具来自SERP统计数据。SERP StatKeyword Research Database Toolis very similar to Google's Keyword Planner. Simply add your query into the search bar and you'll receive results based on volume of searches and CPC.

4. Use the LSI Keyword Generator

TheLSI Graph/LSI Keyword Generator是另一个完美识别LSI关键字的免费工具。类似于提到的先前工具,它遵循相同的冲洗和重复过程。在搜索栏中添加一个术语,单击“生成”,然后从下面的各种相关关键字中进行选择。

lsi-graph-keywords

5. Try Ubersuggest

最后,另一个免费赠品可以发现LSI关键字的ISUbersuggest. I’m sure at this point, you can guess how simple each of these tools are. All you need to do is enter you primary keyword, and Ubersuggest does the rest! From search volume, keyword difficulty, and CPC, you can expect a generated list of related search terms.

How to Select (and Use) the Best LSI Keywords

By this point, it's likely (and normal) to have a long list of potential LSI keywords. The best way to cherry pick the finest keywords is to narrow down your options to those keywords that are most related to your content and have a sufficient search volume. Extra points if you can determine those golden nugget keywords with both high search volume and low keyword difficulty.

了解三种不同类型的意图

It’s vital that your LSI keywords help answer any questions people might have about your primary keyword, so be sure to do some research on your target audience to figure out the types of queries they might put into Google to find your content.

我们将再次参考“愚蠢的字符串”,这次是在该网站上的上下文中,致力于探索“愚蠢的字符串工作方式”。以下是Google上的三种不同类型的意图,在搜索“愚蠢的字符串”时可能会有:

  • 信息意图: This type of query is typically on a much broader scale. An example would be, "How does silly string work?"
  • Navigational intent: This is a more specific type of query. For instance, someone might want to know who invented silly string, or what it's made out of.
  • 交易意图: This type of query relates to purchasing something. In regards to our example, it could be related to purchasing silly string.

选择添加上下文但不要过分夸张的单词

某些人遇到的误解是,您应该使用尽可能多的LSI关键字,以使您的内容有更好的机会超越他人。

This is called overstuffing your content, and it's a practice you'll want to avoid because it could actually deter you from ranking. The best way to make sure your content isn’t overstuffed is to reread your content once all the keywords are added. If a specific word doesn’t sound natural, leave it out.

Remember That LSI Is Only Part of an Effective SEO Strategy

LSI is just potentially one of many factors that determine how well your content ranks in search engines. To achieve the best results and set your content up for success, aneffective SEO strategyshould also consist of proper website architecture, relevant backlinks, ongoing optimizations, etc.

话虽如此,绝对值得花时间在您的内容中发现和添加相关的LSI驱动关键字,尤其是因为它可以帮助您的读者找到最相关,最有用的信息以更快地满足他们的需求。
