Latent Semantic Indexing – Does It Help SEO?

Latent Semantic Indexing (LSI) and Latent Semantic Analysis (LSA) are techniques in natural language processing to analyze relationships between a set of documents and the terms they contain by producing a set of concepts related to the documents and terms.

Latent Semantic Indexing - Does It Help SEO?

I thought it might be helpful to explore the concept of Latent Semantic Indexing and its impact on Search Engine Optimization(SEO). If you research Search Enginge Optimization Techniques you are likely to come across some articles on Latent Semantic Indexing (LSI) or Latent Semantic Analysis (LSA). There is some debate on the effectiveness of creating content designed to appeal to LSI algorithms to improve organic search results placement. My position is that by understanding LSI / LSA you are able to create better content, regardless of whether it improves organic search results on Google, Bing, etc.

What Is Latent Semantic Indexing?

In simple terms, Latent Semantic Indexing allows a search engine to include pages with the text “Home For Sale” in the search results for the search term “House For Sale.” That is because “Home” and “House” are related terms. LSI is a technique that reveals underlying concepts of content by means of synonyms and related words. It is basically using data correlation to find related terms. (see article: A Primer On Data Correlation For Marketers). Latent Semantic Indexing finds hidden (latent) relationships between words (semantics) in order to improve information understanding (indexing).

Latent Semantic Indexing As SEO Strategy

It has been suggested that using synonyms and related terms in optimized website content could help a search engine better understand the content and rank it higher in search results. The idea is to take your target keywords or search term and indentify a list of “LSI Keywords” to include in the content.

Search engines attempt to understand the context of any piece of content they index. The field of semantics (the study of meaning in language) is a fundamental part of this approach.

While it is believed that search engines relied heavily on LSI in the early stages of their development, there is no evidence that the Google and Bing rely heavily on it now.

Why Condisder LSI As Part Of Your Content Strategy?

My opinion is that you should focus on creating good quality content on website vs. trying to game Google or Bing with optimization techniques. As part of my content strategies, I use a basic understand of Latent Semantic Analysis to create better content. Different people may use different terms to describe the same topic, and by including these related terms it can make the content more relevent to the reader. I also use LSA to make sure I am not overusing the primary keywords or search term. I use LSA to come up with derivative articles that are related to the primary article. An effective SEO strategy should also include relevant backlinks, relevant alt tags, etc.

In summary, I am not convinced that using Latent Semantic Analysis will improve your search rankings, but I feel it can improve your content.


Why Open Source?

Why Open SourceThere are variety of good reasons to use open source technology when creating solutions for your business.

Lower total cost of ownership (TCO): Using open source software yields a lower total cost of ownership when compared to closed source and proprietary alternatives.

Shift developers from low-value work to high-value work: The easy problems have already been solved by open source solutions. Operating systems, web servers, content management systems, and databases are all problems with established market leading open source solutions.

Modularity & Flexibility of key components: Proprietary software solutions tend to be monolithic, and you are not allowed to change how they function, or to add features that you need. Proprietary software locks users to a particular vendor, or “platform”. Open source projects tend to be more modularly architected, improving both the flexibility, and the robustness of the code. Open source solutions are typically leaner and more agile. Since you have access to the source code, you can often apply fixes or add features, both large and small, at your own convenience, not at the convenience of the publishing organization’s release cycle.

Secure & Transparent: Empirically, open source tends to produce better quality software than its proprietary or alternative counterparts. With closed source software, the only developers that can potentially detect, diagnose, triage, and resolve software bugs are those that happen to be employed by the company that publishes the software. Open source provides three advantages: first, you have the opportunity to tap the knowledge of the world’s best developers, not just those on one organization’s payroll. Second, the number of potentially contributing developers and thus the potential knowledge pool is orders of magnitude larger. Finally, open source software gets adapted to a variety of use cases, not just the one the publisher originally intended, surfacing bugs and edge cases much more rapidly than traditional, predictive QA processes.


LAMP Stack

LAMP StackLAMP is an acronym for “Linux, Apache, MySQL, Perl/PHP/Python”.

PHP (or Perl, Python)

MySQL DataBase

APACHE Web Server

LINUX Operating System

The reason they call it a stack is because each level derives off it’s base layer. Your Operating system, Linux, is the base layer. Then Apache, your web daemon sits on top of your OS. Then your database stores all the information served by your web daemon, and PHP (or any P* scripting language) is used to drive and display all the data, and allow for user interaction.


Linux

LinuxLinux is a family of free and open-source software operating systems built around the Linux kernel. The development of Linux is one of the most prominent examples of free and open-source software collaboration. The underlying source code may be used, modified and distributed—commercially or non-commercially—by anyone under the terms of its respective licenses, such as the GNU General Public License.

Typically, Linux is packaged in a form known as a Linux distribution (or distro for short) for both desktop and server use. The defining component of a Linux distribution is the Linux kernel. Distributions include the Linux kernel, supporting utilities and libraries, many of which are provided by the GNU Project, and usually a large amount of application software to fulfil the distribution’s intended use.

Linux is the most widely used operating system due to its marketing leading position on servers, mobile devices, and ebmeded systems. It has over 60% market share of web servers. The Android operating system (which runs on the Linux kernel) is the most used operating system worldwide, with its market share reaching 81.7 percent in the last quarter of 2016.

Apache HTTP Server

Apache HTTP ServerThe Apache HTTP Server, typically called simply “Apache”, is a free and open-source cross-platform web server. Apache is the most widely used web server. As of March 2018, the Apache web server was estimated to serve 43% of all active websites and 37% of the top million websites.

The Apache web server supports virtual hosting. This allows one Apache installation to serve many different Web sites.

Apache uses compiled modules to extend the core functionality. These can range from authentication schemes, popular compression methods, to supporting server-side programming languages such as Perl, Python, Tcl and PHP.

Instead of implementing a single architecture, Apache provides a variety of MultiProcessing Modules (MPMs), which allow it to run in either a process-based mode, a hybrid (process and thread) mode, or an event-hybrid mode, in order to better match the demands of each particular infrastructure.

MySQL

MySQLMySQL is an open-source relational database management system (RDBMS). MySQL is a central component of the LAMP open-source web application software stack (and other “AMP” stacks). LAMP is an acronym for “Linux, Apache, MySQL, Perl/PHP/Python”.

MySQL performs extremely well for most uses. It has been tested to be a fast, stable and true multi-user, multi-threaded sql database server. There are numerous developer interfaces, and the documentation is very good. It has been tested to be a fast, stable and true multi-user, multi-threaded sql database server.

PHP

PHPPHP: Hypertext Preprocessor (or simply PHP) is a server-side scripting language designed for Web development, but also used as a general-purpose programming language.

PHP code may be embedded into HTML code, or it can be used in combination with various web template systems, web content management systems(like WordPress), and web frameworks. PHP code is usually processed by a PHP interpreter implemented as a module in the web server or as a Common Gateway Interface (CGI) executable. The web server combines the results of the interpreted and executed PHP code, which may be any type of data, including images, with the generated web page. PHP code may also be executed with a command-line interface (CLI) and can be used to implement standalone graphical applications.

WordPress

WordPress

WordPress powers 31% of the Internet.

WordPress is a free and open-source content management system (CMS) based on PHP and MySQL. WordPress is the most popular website management system. It is used by more than 60 million websites, including 30.6% of the top 10 million websites.

Features include a plugin architecture and a template system. It is most associated with blogging, but supports other types of web content including more traditional mailing lists and forums, media galleries, and online stores.

WordPress has to be installed on a web server, either part of an Internet hosting service like WordPress.com or a computer running the software package WordPress.org in order to serve as a network host in its own right. A local computer may be used for single-user testing and learning purposes.
