SEO stands for Search Engine Optimization. The algorithm that improves the traffic on web servers by increasing the visibility of relatable web pages that are accurate to the search query. Link building is a massive part of SEO. 

So, how why links from your blog to other websites or pages on the internet? How many links should be in the blog post? There are two types of them: external and internal. Both are important. 

Quality external links in your post content are building authority for the content you created and provide additional resources to your readers. 

Internal links play a huge role in a website’s ranking — from its crawlability by search engine bots to the ranking authority distribution between a website’s pages.


How Many Links Should a Blog Post Have?

There is a simple answer to this question: use common sense and this rule of thumb: 

Don’t: Overwhelm Your Reader. Try and stick to three to five (3-5 per 1000 words) inbound and outbound links per 1000 words.

There are few Do’s and Don’ts of Links within your blog posts that are clearly explained in Kapost blog post. One of them to remember:


Blog SEO: link types

External Links (also known as outbound links)

– are when you link to a site outside of your web domain. It is sometimes that you need an assist from other websites and the content they offer. So the links that guide the user to another site for viewing of relatable or extended material are known as external links.

A most basic example of External links is Pinterest. Pinterest offers the thumbnail display of images regarding the searched keyword. Those thumbnails are supported by external links that lead the user to different websites where that picture initially belongs to. May that be a news article, entertainment magazine, or a photoshoot album.

Internal Links (also known as inbound links)

– are the links that direct the user to another page of your own, same website. For example, you may link to another post on your blog, or your “Services,” or “Contact” page. The deeper within your website, the internal link resides, the more valuable it is to add since the reader would be unlikely to find it on their own otherwise. Why would you make the user go through the hectic routine of searching a relating, regarding content and pages on websites through search engine lists, when you can provide the link in your Blog Post Article.

A basic example of Internal links is Facebook. Facebook directing users to different profiles and pages within their website’s domain. 


Benefits of external and internal links

External Links: 

  • Builds trust. Linking to authoritative external sites increases the popularity of a given web page. External links can affect the reputation of your site. Since the search engine sees the relevant content of high authority domains linked from your website, it can better understand your niche and subsequently trust your website. 
  • Builds brand. Linking to other websites sites can build relationships and expand your reach. If you create an external link from a blog post to another business, their SEO manager may notice the new backlink from your site. You are starting to build a relationship with the others, and it can lead to the beginning of a mutually beneficial connection. Other businesses can reach out to you and potentially can backlink to your site too. 
  • Increase loyalty. Your willingness to include external links to provide more valuable information for your customers demonstrates that you care about them. You provide them with the resources they want and need to fully explore the topic, so you include external links to accomplish that. 

Note: Great sites typically link to other great sites. 

Internal Links

Having too many external links can be annoying from the perspective of your readers. Focus more on internal links. 

  • Internal linking makes your site way more user-friendly. Instead of having to search through your lengthy blog archives or heading to the main website menu every single time they want to find the link they need, it’s already there in the content/blog you provided. It is placed in the right spot at the right timing where it’s most relevant and required for the reader. With plenty of keenly planned internal links, your site becomes helpful and easy to navigate through, tempting your web page visitors to come back. They make your site easy to engage with and attractive to readers.
  • Internal links boost your SEO. When outside sites naturally connect to your website, Google sees your site as more valuable, it will increase your site’s chances of appearing more in number and higher in ranking on their search lists.
  • Internal links keep readers engaged. They tend to spend more time on your site rather than diverting to other websites. This decreases the bounce rate of your site’s traffic. Internal Links make your site an all-points-joined map. Separating the contents and making your site look more arranged and organized. This makes your readers spending more time reading old blog posts on your website, learning new information, and becoming more familiar with your site better. 


Impact of External and Internal Linking on SEO

There are a lot of factors that need to be considered when search engines like Google have the power to determine ranking factors and are thus more visible to a viewer. Internal and External links are a critical component of a strong SEO strategy and help boost SEO ranking power. It may take time to master this link building process. It’ll increase traffic to your site and improve your site’s rank on the search engine’s results page. 

Internal Links and SEO:

Internal Links improve your ranks and standards under general SEO parameters by creating a more organized and structured interface for users. Readers come to a Blog Post Article Site, seeking knowledge they desire to gain. Knowledge is directly proportional to curiosity. Curiosity for a specific topic increases when you go through a high-quality article on a site. When a reader demands more, there is nothing better than the sight of a website providing inbound links to other relatable and linked articles, separated by schema, but present on one site’s domain. A website with Internal links is treated as a vast platform, even if it isn’t that broad. No reader can go through every single article on a blog site, but when a site offers links to another article on the right spot and correct timing, the reader will not only rate it high with great feedback but will also revisit for more. This will help you with improving your ranking by the standards of SEO.

External Links and SEO:

External links improve your ranks and standards under general SEO parameters, by creating outbound relationships with other highly ranked, renowned, and trustworthy sites. A site committing a selfless and temperate act of providing paths and bridges to other websites for the convenience of your reader, when you have nothing to benefit off of it, surely impresses a visitor. Not only that, but when other deserving sites notice the traffic deviation towards their servers, coming from your site, they keep you in high regard. Not that it only creates real opportunities for such brands reaching out to you and merging, but it also creates undercover links between you and top-ranked sites that you mention in your externals, in the hierarchy that is only noticed by SEO algorithms. Therefore, that will surely improve your ranks in SEO search lists.
