 Introduction To The 6 Best Free WordPress SEO Plugins

A website is one of the most crucial parts of every business. Yet, many businesses don't have one. To them, it is a waste of money spent on running a website. Why? Because you can easily create several social accounts without paying any money, right? You are free to advertise your products or services and expand your business. So, why should we have a website for our business? We are going to answer this question!

OK! Let's say that having a website for your business is vital for the sake of an argument. However, how are we going to create and run it? Businesspeople are swamped with their meetings and workloads. They have to take care of their bank accounts, deals, etc., not their website! Also, they might not be able to afford the cost of hiring web developers to create and manage their websites.

Thanks to the latest technologies, running a website is not as hard as you might think. And, that's the key to website-use popularity among businesses. Today, we are going to talk about the necessities and requirements for a business website.

There are several key elements every website should consider to make an impact. Also, we discuss the best WordPress SEO plugins. Don’t you know about WordPress, SEO, or plugins? Don’t you know what they do for your website? Don't worry! We will cover these questions too. Let's get started.

What Is WordPress, And How Does It Help Us?

To understand what WordPress is, you have to ask another question. Actually, you should ask what it can do for us which wasn’t possible before. Then, you might understand the definition better. Basically, WordPress frees you from all the limitations people used to have. For example, people had to know how to work with HTML, PHP, and CSS.

Working with these coding languages could be very hard and a waste of time. With WordPress, you don’t need to know any of these hard words. It makes it super easy for everyone to create and manage a website. That's why nearly 35% of all websites on the internet are using WordPress.

To make it a bit more specific, WordPress is software for creating websites. Who is behind this software? In fact, nobody and everybody. What do I mean by that? It means that thousands of people in the world started building it up. Now, thousands of people are updating it a day today.

Another important feature of WordPress is that it's free to use for everybody. At first, WordPress was designed only for blogging. However, now, it can be implemented for any kind of website, including commercial, business, social, etc. In addition to websites, WordPress has been recently used for mobile applications.

How Does WordPress Work?

If you want to understand how WordPress works, you should know the basics of your website. Let's begin. Well, first things first. Your website has a domain name and host. Basically, a domain name is your website's address. The host also works as a house for your website where you can put all your information in. Now, WordPress comes into the picture. WordPress as software helps you manage your domain and host.

In fact, WordPress manages all the content on your website, including videos, images, text, etc. That's why we call it a content management system. WordPress is based on PHP code. Also, all your content is stored in your WordPress database. To put it simply, WordPress can support PHP and create a database for storing information.

The Difference Between WordPress.com And WordPress.org

To find out more about how WordPress works, you should know the difference between WordPress.com and WordPress.org. WordPress.com connects WordPress with the domain & host. There are limitations here because they don’t want you to control the host. In WordPress.org, however, you have the option to choose any hosting companies you want. So, you have more control over managing your website. It is easy to install WordPress with all well-known hosting companies.


Elements Of WordPress, Plugins And Themes

WordPress has simple designs and functions. What should you do if you want to add more designs and functions? That's where themes and plugins come into the picture. So, you will install plugins and themes on WordPress to enable you to design a better website and add wanted functions to it. Amazingly, hundreds of plugins and themes are available on the internet, and all of them are compatible with WordPress. Installing these themes and plugins are also very easy. So far, we have talked about the basis of your website.


Content, The More Creative, The More Traffic

I'm sure you have heard of SEO a lot! People say SEO is the most important feature of your website, which leads to more reach and, finally, more sales. WordPress with all those plugins and themes are there to show your content as professionally as possible. Depending on your niche and target audience, you should create your content differently. Understanding SEO principles is fundamental to your website. Your website might have the best charming look. However, with low-quality content, you should not expect to get too much traffics.
