Therefore, you require technical SEO services to improve the user experience of your website to help you attract more traffic and clicks.

This article will explain the components of technical SEO and also share a list of the top technical SEO services you can partner with for your next marketing campaign.

Let’s begin!

What is SEO?

SEO stands for search engine optimization. It enhances your website UX and increases the domain authority score to help it rank higher on search engines like Google, Yahoo, Bing, and others.

When you perform SEO on your site, your business website becomes easily visible to relevant prospects when they search for products and services related to your business.

A good SEO strategy helps improve the quality and quantity of your website traffic. It helps in creating organic leads and conversion to your site.

SEO is considered an investment rather than a cost, as the potential return rate is massive. It is one of those marketing channels that offer free access to a large audience searching for the product that your business is selling.

What does an SEO Agency Do?

An SEO agency is a marketing firm that offers search engine optimization services to help your business improve and enhance its online visibility.

Here are the services that an SEO agency provides:

Goals and KPI setting
Competitor analysis
Technical SEO audit
On-page optimization
Link building
PR management
Social media optimization
Core web vitals optimization
Analytics set up
Goal and conversion tracking
Reports and weekly updates

Technical SEO Checklist

Here is the technical SEO checklist that an SEO agency should offer:

Website Audit

Website audit identifies web page performance issues to improve the user experience. Examining your website helps you decide the strategies you need to implement to improve your rank positioning.

The top elements included in the website audit are:

The current search engine positioning
Site accessibility check
Keyword Analysis
Content quality evaluation
Website architecture and design analysis
External and internal link analysis
Core web vitals test
Broken links and indexing issues check
Structured data optimization

Site Structure Analysis and Development

Site structure analysis, also known as website optimization, is the first step in improving your website. This analysis boosts your ranking on search engines like Google and Bing.

Having a correct site structure is crucial for optimization, as a clear website structure directly impacts users’ behavior and the bounce rate.

Under site structure analysis and development, a technical SEO company plans the best content structure for your company. It includes creating a hierarchical content structure with easy navigation and ensuring no link on your page is more than three clicks away.

Implementing Sitemap and Robots Files

A sitemap is a file where you provide all the details of the pages and content on your site and links between them. Search engines use this file to crawl through your website more effectively, and robot files help these search engines to crawl over essential URLs.

Implementing sitemap and robot files on your website helps you decide your site goals before creating content. This clarity ensures that all the content on your website is valuable and every part reinforces your goals.

Compiling and Placing Relevant Meta Tags

Meta tags are the pieces of text that best describe your web page’s content. They are not visible on the main website content but only in the source code.

Meta tags include all the essential information of a web page; the developer combines all the necessary tags and places them on the head part of the website’s source.

Fixing Pages with 404 Server Responses and Unnecessary Redirects

Error 404 occurs when the crawler tries to visit a web page that fails to exist on a domain. Fixing the 404 server response means trying to resolve the issues that led to the web page’s denied access.

Unnecessary redirects mean moving your site visitors to a new location which can be frustrating for the users leading to reduced conversions. This problem can be fixed by various methods, such as clearing cookies and browser cache on the redirecting site, evaluating your third-party plugins and services, etc.

Canonicals setting up

Canonicals are the tags that tell Google that a specific URL represents the master copy of a page. Setting up canonicals helps you identify and rectify the problem of duplicate content appearing on multiple URLs.

Image Optimization and Alt Attributes Fill In

Image optimization helps in improving the webpage’s speed, boosts your site ranking, and provides an improved user experience.

Alt attributes are the HTML tags that are put in with image tags to provide textual alternatives for search engines. Filling in alt tags is essential to describe the image’s meaning to the search engines.

Pages speed optimization

Page speed means a page’s performance and load time on multiple devices. Optimizing your page speed means adopting measures to reduce the loading time of your web page by different methods.

Here are the ways by which you can increase your page speed:

Enabling file compressions
Reducing redirects
Clearing browser caches
Improving server response time
Optimizing content images
Fixing 404 errors

Implementation of structured data

Structured data is a set of well-organized data that helps search engines better identify and understand your website. This data helps search engines to create informative and rich results for the end users.

Here are various tools to implement structured data on your site to make it more accessible to search engines:

Google’s Structured Data Testing
Google Codelab
Schema.org
Snippertron
Knowledge Navigator
JSON-LD Schema Generator

Content optimization and link building

Content optimization is creating and amending your content in a way that is easily visible to a larger audience on the web. The process includes creating high-quality content based on relevant keywords and adding relevant meta tags. Highly lucrative content ranks higher on search engines when people search for the specified keywords.

Link building is an optimization technique where other relevant domains on the web link back to your site. This helps boost the page authority by showing your website as more relevant and valuable in the eyes of search engines to increase traffic and ranking.
