The 4 Types of SEO?

Types of SEO

There are several types of search engine optimization.

It is important to know what they are when attempting to choose an SEO service for your site.

You can make a lot of mistakes if you do not know what each type of SEO entails.

You should also know how they all work together to build a successful campaign.

Search engine optimization (SEO) has evolved over the years.

Gone are the days of stuffing your keywords in the title tag. It is also extinct or thinking you’ll rank if you have 300 links pointing to your site.

Google is a lot smarter today than it was yesterday. That means optimizing your site is more complicated than it was 10 years ago.

Nothing can be more beneficial for your site’s rankings in search engines than an SEO strategy.

Nonetheless, it is challenging to choose the right one which works for your niche. The thing is that there are many types of SEO.

Before you start working on your website SEO campaign, select the type of optimization you will require. Some of the types of SEO are;

1. On-page Search Engine Optimization

On-page SEO is one of the most important aspects of your site’s visibility to search engines.

It’s all about improving your content so search engines can more easily crawl your site and see your content.

When executed correctly, a website’s on-page SEO can make an enormous difference. This is visible in the amount of traffic, it receives from search engines.

The success of your user’s experience on your site will depend on how easy and less cluttered the page is.

Also, if it provides meaningful information to their query. Search Engines optimize their algorithms and methods to serve the best results to their users.

Hence, our main focus should always be the searcher. If they don’t see anything valuable or interesting then they will find another site.

On-page factors such as a title and Meta description can sometimes seem like trivial elements when designing a website. 

Yet if configured correctly, they can play a pivotal role in how your content is found on the SERPs.

On-page SEO refers to the various SEO aspects related to your website’s content (including Meta tags). 

This includes the title, keywords, Meta description, header tags, alt tags, etc. 

On-page search engine optimization tips include several items that can help to boost your rank in the search engines and get you more traffic.

2. Off-page Search Engine Optimization

Many important factors help determine the search rankings of a particular webpage in the search engine results page (SERP). 

One of the most important of these factors is Off-page Search Engine Optimization.

Off-page search engine optimization refers to the activities that influence how your website is perceived by both search engines and users. 

These activities include building quality links and participating in online social media communities.

Off-page optimization is very important for your website. It paves the way to search engines. It is termed off-page because it’s done away from the core website.

Note that redirect links are amongst the best off-page SEO strategies you can implement in your website.

3. Technical Search Engine Optimization

If you want to rank on the first page of Google, you will need to work on technical SEO. 

Some people have created all kinds of strategies that involve link building and outsourcing content creation. 

If you are serious about getting traffic, and as a byproduct, create profit, you need to work on technical SEO.

Technical SEO is the cornerstone of a successful SEO campaign, but it is usually given the shortest shift. 

Hence, it is important to watch out for some pitfalls while carrying out technical SEO correctly.

4. Local Search Engine Optimization

Local search engine optimization is an emerging form of SEO that many don’t know exists. What happens when you type your query in the search engine?

You get SERPs, which are listings of all the websites that have ranked based on what the algorithm has picked. 

However, these listings, are based on distance from your location (see Google My Business).

Most websites today rank well in search engines for the keywords that they target. 

Nevertheless, most don’t even comprehend that there may be other opportunities for them to get local traffic. 

Businesses that take the time to learn and understand local search will be rewarded with more leads, more customers, and more business.

What are Keywords?

Keywords are words or phrases which a user types into Google search engines to retrieve relevant information on the Internet.

Keywords are used very often during Search Engine Optimization (SEO) as a crucial tool for the optimization of websites.

A keyword is a word or phrase which contains your targeted search that people look for. 

The purpose of adding a keyword is to find people who are searching for something. As a result, you can match them with something they might be looking for.

There can be too many searches for you to dominate in the SERPs. In such a situation, it is necessary to narrow down the search using keywords.

Your customers use keywords to look for solutions to their problems. Keywords are the language people use to find what they need on the web. 

If you want your website to be discovered by search engines, you need to adopt keywords.  

You should write content that appeals to those keywords and phrases relevant to your products or services.

Keywords are one of the main concepts for search engine optimization (SEO). 

They allow people to find your content through search engines. 

If you’re looking to optimize your website for search engines, then you should already have a keyword strategy in place. If you don’t, it’s time to get started.

Types of Keywords

There are a few different types of keywords that you should be focusing on. 

They help to make sure that your site gets higher rankings from the search engines.

Keywords, as most SEO’s know, are words or phrases people use to search for products and services. 

The more keywords you target with your website the better.

Keywords form the foundation for improving your search engine rankings. 

Knowing what types of keywords to focus on will help you improve your site’s visibility online in a short period.

There are many types of keywords that we can target as SEOs. 

However, it is a long walk to list off every single keyword category that is out there. 

Instead, you should understand why they are important and when you would use them.

Understanding the different types of keywords will help you narrow down your focus and find the best ones to use for your project. 

Hence, we would examine some major types of keywords.

Types of Keywords according to their uses

1. Informational Keywords

Informational keywords are searches that people use to find information.

They are used when a person doesn’t know the specifics about what they want. However, the searcher has some familiarity with that area.

Informational keywords are all about educating users and not directly selling. They are usually “how-to” questions. 

They are about enriching the user’s experience in what they are searching for. 

They evolve around curiosity, understanding, and general information.

These keywords have to do with defining questions that people have about things or events or places.

For example: “what continent is Canada located in?”; “Who is the president of America?” “How to fly a plane”

2. Navigational Keywords

Navigational keywords are also known as ‘long-tailed keywords’. They can be very useful in helping a site rank higher for less competitive search terms. 

Navigational keywords are related to the main keyword phrase. It is usually with one or two words before the main keyword.

Navigational keywords are the most important to use while you are creating Content Plans for your website. 

These are the words that people type in the search bar of a Google search that direct them to your website. A good example is your domain name.

They help visitors to find information on your site and are also known as “search terms.”. 

Navigational keywords are not used in the content of your articles or pages. Instead, they appear in the software code of your website.

3. Commercial Keywords

Commercial keywords are terms used by a person looking to buy a product or service. 

Online sellers need to define their target customers to create highly relevant content. 

Finding the commercial keywords allows online sellers to define their target customer base during this process.

There is a reason these keywords are known as “commercial”. 

This is because these terms have the highest potential to draw numerous visitors to your site. 

These terms generally consist of multiple words used together with some great benefits attached to them. 

It also comes with some great traffic. This is made available for the people who put it up on their sites and use these terms as the pages.

Types of Keywords According to their Structure (SEO Keywords)

1. Short tail Keywords

Short tail keywords are small, specific keywords that have low competition, but a relatively high search volume. 

Short tail keywords are a type of keyword that contains 3 or fewer words.

2. Medium tail Keywords

Medium tail keywords are referring to keywords with 2-5 words. 

Unlike long-tail keywords which have low competition, in medium-tail keywords, the competition is still very high. 

Nevertheless, it is not as high as short-tail keywords.

By understanding what Medium Tails keywords are, you’ll have a good handle on the complexities of long-tail keywords. 

You would also be able to identify opportunities to increase your rankings.

3. Long-Tail Keywords

Long-tail keyword phrases consist of a few too many related words. They are longer and less intuitive than keywords. 

The longer the phrase, the more unique it is to the searcher’s query.

Long-tail keywords are phrases with more than three words. 

They include a term or phrase that is modified by several descriptors and modifiers.

In simple terms, the longer your keyword is, the less competition there is for it. 

Put plainly: Long-tail keywords have less competition than short head phrases. 

This does not mean that long-tail keywords have no competition at all. 

It means that they simply have less competition; making them easier to rank for.


What is Keyword Research?

Keyword Research is the process of finding what people search for in the search engines to find solutions or products.

The keyword research should be done depending upon a particular industry, niche, and user behaviours.

Keyword research is just as important as content creation in regards to creating a successful website and blog. 

You can’t even create great content without knowing what words you should use in the first place. 

If you don’t know what keywords to target and optimize for, it all becomes a moot point. This is why keyword research is so vital.

Keywords are what you type into a search engine to find information. 

A keyword can be a word or phrase that describes what you are looking for on the internet.
