Technical For SEO

SEO is not only about content, there is the Technical Knowledge for SEO.

You don’t rank just by a bunch of keywords related to your service.

SEO is a bit (a lot) more complicated than that. However, don’t be scared. It’s not rocket science!

How far should you go with Technical Knowledge for SEO?

Anyone can master the technical knowledge needed for SEO! Learn how by reading this article.

Please note that we are not saying you should learn how to do technical stuff since you can hire a developer.

Also, there are a lot of plugins and extensions that would do all of that for you.

However, having a bit of information about the non-visual side of SEO can make you better at it.

Why? Because you would understand what does what, and you would be able to save a little money if you are just getting started. (By doing the technical work yourself).

We will (try to) explain some definitions of standard SEO terms that are used in the technical side.

Let’s dig into the Aspects of technical SEO, and what knowledge you need for it.

Offsite Technical SEO Knowledge: 

Before optimizing your site, you must create a site!

A website, as easy as it gets, is constructed of an IP address, a host, and a Domain name that points to the IP address.

Why are we bringing this up? Because Domain Names affect SEO! 

At the very least, you should be able to buy a domain name by yourself, and subscribe to a web host, and, obviously, understand the difference between them.

After creating your website, you should secure it! That’s done via something called Secure Socket Layer (SSL), which is a technology that assures a secure connection between the web server (on which your web host is) and the user’s browser. Your network potentially harbors security vulnerabilities which will allow attackers entry into your system. When you hire, one of the first things they’ll do is to audit every nook and cranny of your network for weaknesses.

Finally, You should be able to submit your site into Google Search Console, and Bing Webmaster tools, in order to index your website, and make Google and Bing index it!

Onsite Technical SEO Knowledge:

After You’ve built and indexed your site, you should know how to optimize it for SEO.

1- Understand meta tags correctly:

Meta Tags and Technical SEO

  • Meta tags are snippets of code that serve as a guide for search engines on how to display your content.

  • Google cares a lot about your meta titles and descriptions.

  • If you’ve built your site manually (“From scratch,” as they say), you would have to add them manually between thetags.

2- Images:

  • When uploading images, learn how to use  HTML “ALT” tags correctly, which are also HTML attributes (code) added to images.

  • Know the difference between PNG, JPG, JPEG, WebP, and Other formats: JPEG is suitable for colors and clarity.

PNG is better when you need a transparent background, and WebP is one of the most optimized formats ever, use it when possible.

3- Header Tags:

You might think Headers or “H Tags” are HTML tags that make the text appear bolder. However, they are much more than you might expect.

You should always include keywords in your H tags since they represent the structure of your content. Therefore they make search engines understand what you are writing about.

If implemented correctly, Headers can improve your SEO in a significant way!

Now let’s get into some advanced stuff; hopefully, you still with us until this point!

4- Schema Structured Data:

A collection of tags (HTML) that’s used to give semantic value to Search Engines results, they can be applied in things like events, authors, products, and others.

It’s not clear whether Schema Structured Data improves SEO or not. However, they positively impact click-through-rates!

5- Robots exclusion protocol or standard (robots.txt) file:

In a nutshell: they are files that help search engine crawlers do their jobs.

Such files decide which pages of your website should be crawled by Google, Bing, and others.

Having an optimized robot.txt file could result in a better ranking on SERPs.

You should learn how to find them, edit them, and add them to your HTML!

Fixing Technical SEO Errors:

You should always do a technical checkup on your site to ensure there are no errors in the backend affecting your rankings!
