SEO Blog User Experience (UX)

Quality assurance is necessary to control the efficiency and productivity of the developed sites. In addition, quality assurance allows you to manage website data. From the test results, you will find out how the site meets the quality parameters the needs of consumers and customers. Finally, and most importantly, quality assurance will help you identify flaws.

What is Quality Assurance?

Quality Assurance is a system for determining whether a site meets the stated requirements of a specification or documentation. A quality check identifies errors, improves the workflow and the website itself, and increases the competitiveness and credibility of the company. In addition, quality control assures that requirements will be met. Quality assurance is based on two principles: “fit for purpose” and “right the first time.”

Options for usability analysis and site testing:

  • UX Check. How the user goes along the conversion path, what can interfere with him and what can cause the user to leave the site. Use our tips to improve the situation: https://www.plerdy.com/use-cases/
  • SEO Check. Checking for the presence of tags necessary for SEO, namely title, description, no-index, no-follow, canonical, h1, h2, h3, and others.
  • Functionality Check. For example, this will be the work of searching, filters, ordering goods, etc.

It is worth noting that quality assurance and quality control are not the same things. We’ll talk more about this later. In the meantime, let’s look at why quality assurance is so important when developing and bringing a site to market.

Importance of Quality Assurance

Neither the design of the site nor the concept can smooth out errors in the work or shortcomings in the site’s quality. But these are not all the reasons you need to provide quality assurance. We present seven more:

  • Saving time. Determining requirements checking for QA errors at the start takes much less time than finding and fixing defects after the site is launched on the market or even at the finish line of development. They use recordings of video sessions and Plerdy click maps to do this.
  • Saving money. Quality assurance is costly initially, but it pays off in the long run. This way, you will avoid losses due to low sales, reputation loss, demand, and bug fixes.
  • Clients’ trust. Getting quality results is a priority for clients. It is in your interest to satisfy their requests – this will bring profit and raise the company’s status. And caring about achieving the goals of customers is precisely what they need. So no one will mind if you say that you organize quality assurance.
  • Improvement of user experience. The slow work of the site page the issuance of erroneous results – in any case, this will lead to user dissatisfaction and refusal to use your site. With quality assurance, you can avoid this.

Quality assurance is the basis of business culture. This is the rule that sets the tone for the business.

Software Quality Assurance

SQA or software quality assurance is a parallel process to development. It is carried out throughout the entire life cycle of the product. SQA ensures software quality following ISO 25010, SPICE, or CMMI standards. To do this, use the tools prescribed in the SRS – software requirements specifications.
