Top 4 SEO tools to boost your site in 2021

Every website or blog owner out there is concerned with online visibility and ranking high on search engine searches, especially on Google search. In this article, we have curated the best SEO tools to boost your site’s chances of ranking high on search engine result pages (SERP) when people search for keywords related to your website. This is known as search engine optimisation (SEO)

One may keep a diary to hide their thoughts secret but that is not the same with a website. For anyone who creates a website for whatever reason, online visibility is a big deal. There are several means to achieve this, one of the most effective is SEO.

What is SEO?

If you stay around blog/website owners or administrators, SEO is a term that you would hear – a lot. Nothing gets that much mention and popularity without good reason, right? Before we dive deeper, let’s find out what all the fuss is about then.

SEO simply stands for Search Engine Optimization. Defined simply, it is the art of ranking high in the Organic Listings of search results. The Organic Listings are simply the unpaid sections of results search engines bring back. 90% of the time this search engine is Google.

The only time anyone ever goes to “page 2” and beyond of a Google search is if they’re doing that horrible class project, which even the library is short of resources on (you would be surprised that there are people who are oblivious to the fact a Google search result produces more than a single page). In fact, people hardly look beyond the first 5 results, and Google wants it so! This is because they want more people to trust their search engine as their guide on the internet. So far, they are achieving that aim because according to Internet Live Stats, there are 40,000 search queries every second on average.

When you remember that you are surely not the only one delivering that content you share on the internet, the last thing you want is to get lost in the pile among those over 3.5 billion searches run daily by internet users worldwide.

SEO is therefore how you make your content likely to be at the top of the pile when someone searches a keyword related to your article. In other words, SEO is how you make your website Search Engine-friendly.

Some statistics to make you think

So, you’ve read all the things about SEO and have a very basic understanding of what it’s about. Your next question could be how important SEO is. Well, here are some statistics to highlight the importance of SEO in generating traffic.

According to research by Conductor on 30 websites in 6 different industries, 64% of visits came from users being redirected by links in organic searches. In fact, by far more people click on the top organic result than the paid Google Ads. The reasoning for many is that anyone can pay for an ad but you have to be top of your niche to have your site sitting pretty at the top of search results.

This is why in any given Google search, the top organic result has a 32% click rate. Results 2 to 5 get a combined 36% click rate. This means everything else – results 6 to the last page and paid ads share a combined 32%. That’s a measly Click Through Rate (CTR) for that many search results to share.

Putting all these in context means having great SEO is more valuable than paid ads.

A crash course on search engines

Search engines are websites used to look up information on the internet. They do this by looking through many webpages and looking for results that are most relevant to the user’s query. This query, which is usually inputted in the search bar, is known as the keywords.

Google is unsurprisingly the most popular search engine in the world. That fact is the reason they are the guys whose “good side” you really want to be on. A basic understanding of the criteria with which they rank their sites is important. Google has over 200 ranking factors, most of which are kept secret.

However, knowing the basic ranking will put you in a better position to judge why some tools will help your website’s SEO. Before we go into some of the popular SEO tools, here is a list of Google’s top 10 ranking factors

Google’s top 10 ranking factors in 2020

  1. A Secure and Accessible Website
  2. Page Speed (Including Mobile Page Speed)
  3. Mobile Friendliness
  4. Domain Age, URL, and Authority
  5. Optimised Content
  6. Technical SEO
  7. User Experience (RankBrain)
  8. Links
  9. Social Signals
  10. Real Business Information

Ranking the right way

There are several means of meeting Google’s criteria for ranking high. However, search engines have guidelines for ranking correctly. Find below a summary of Google’s guidelines.

Basic principles

  • Make pages primarily for users, not search engines
  • Don’t deceive your users
  • Avoid tricks intended to improve search engine rankings. A good rule of thumb is whether you would feel comfortable explaining what you’ve done to a website to a Google employee. Another useful test is to ask, “Does this help my users? Would I do this if search engines didn’t exist?”
  • Think about what makes your website unique, valuable, or engaging

Things to avoid

  • Automatically generated content
  • Participating in link schemes
  • Creating pages with little or no original content (i.e. copied from somewhere else)
  • Cloaking — the practice of showing search engine crawlers different content than visitors.
  • Hidden text and links
  • Doorway pages — pages created to rank well for specific searches to funnel traffic to your website

Anyone interested in the long-term success of their organic online visibility would not take shortcuts. These short means are known as Black Hat SEO. The long-term result of using these strategies ranges from creating awkward, spammy websites to being blacklisted by Google.

Also, being blacklisted in visitors’ minds is not a good thing. Users are not likely to revisit a site built on clickbait without substance. Our concern then should be on White Hat SEO strategies and the best tools to achieve these.
