Search Engine Optimization or in a shorter term, SEO, is a method to increase the quality and quantity of your website traffic through organic search results in search engines. Along with that, this will also increase the audience engagement on your web-page.

Search engines are web-based tools that allow users to discover information on the World Wide Web. Popular search engine platforms are like Google, Yahoo, Bing, etc.

You may probably have heard or glanced through this term before, but not many marketers could grasp the ideas of SEO due to its complexities and broad functionalities that it holds.

Let’s take a look at the basic knowledge of SEO deeper.

Basic Knowledge of SEO

To fully understand what goes into SEO, we have broken down the basic definition of it into parts:

Quality of traffic: The term ‘quality‘ here means you’re not only trying to attract the audience to your website, but you’re also trying to get them genuinely interested in the products and services that you offer.

Quantity of traffic: ‘Quantity here refers to the amount of engagement your web page is receiving when you have the right target audience clicking through the search engine results pages (SERPs).

Organic results: When you search for something in Google, it gives you two types of search results – paid and organic.

In this case, organic results refer to Web page search results that nearly match your search query based on relevance. Also known as “natural” search results, getting high ranking in organic results is what SEO all about. Take a look at the figure below for your guidance.

Meanwhile, paid results mean that you, as website owners, have your web pages paid to display for certain keywords on the search engine results pages. So, the search listings will show up when your target audience runs a search query containing those keywords.

You can easily differentiate between paid and organic results based on their positionings in the search engine page results. Take a look at the figure below for your clarification on the differentiating paid results and organic results.

Using this approach, it will reduce the likeliness to get your website negatively affected by search engine algorithm updates that are consistently done 500-600 times yearly.

3. Grey Hat SEO

While there is White Hat SEO and Black Hat SEO, there is another approach that lies in between these 2 approaches called Grey Hat SEO.

The practices in Grey Hat SEO are riskier than White Hat SEO, but it may or may not result in getting your site banned from search engines.

However, it is important to have a clear understanding of this approach. This is because they are slightly unethical and the tactics are not normally outlined in the webmaster guidelines. Also, its terms of service are a bit vague.

Techniques of Grey Hat SEO:

Some of the Grey Hat techniques that you should know are:

  • Cloaking
  • Purchasing old domains
  • Duplicating content
  • Fake reviews
  • Social media automation

Let’s take a look at each of these techniques carefully.

1. Cloaking

Cloaking is a technique of showing users a different result than it does the search engine. In simpler words, it is a form of 2 different pages of the same URL. It is considered to be a risky method for Google as it violates its rules.

Try to watch the video below by Matt Cutt for a clearer understanding of cloaking in practicing SEO.

It is mentioned in the video that cloaking is not a method that is approved by Google. This is because cloaking can be done through changing meta information so that it doesn’t plagiarise the original content and alter the IP address of the site.

2. Purchasing Old Domains

This method describes the purchasing of an old website that has been abandoned or the owner itself is inactive for a long time.

You can purchase the old domains as a method to create backlinks in order to increase your search rankings by using the domains with high authority, domain age, etc.

However, this method may be a bit risky as Google may detect this action and decide it doesn’t count.

Either way, it is not costly to achieve the SEO advantage. The figure below shows the screenshot from a video about buying expired domains that Brian Dean from Backlinko did for Quicksprout.

3. Duplicating Content

Content duplication will not increase your rank on search engine results pages (SERP). This is because Google or any other search engines can easily detect the copied or dummy content on your website.

If you want to keep the duplicated content on your webpage, you can go for a canonical attribute on URLs. This attribute will notify Google that the content on your site has been duplicated. Hence, your website ranking will be the same.

You can also use plagiarism tools to produce high-quality content. Besides, content with zero plagiarism will lead to a high ranking in SERPs.

4. Fake Reviews

It is recommended by Google to not use this technique. The reason is that using reviews from fake accounts are easily detected by Google by using an IP address or cookies.

5. Social Media Profile Automation and Buying Followers

In social media profile automation, it allows you to create auto social media posts by using specific tools that will help you save time when managing multiple accounts.

Buying followers may seem like a quick idea to increase your page ranking.

However, little did you know that this method means there is no social engagement and possible risks to get your true followers affected by dangerous viruses and malware.

This is closely considered as Black Hat social media techniques because you’re basically using ‘shortcuts’ to make your social accounts look amazing than it actually is. You can check out the article here on the Black Hat Social Media Techniques that Your Brand Shouldn’t Use for more information.
