Web Design FAQs

What are the steps to designing a website?

At Spark, our website design and development services involve a process that has been tried and tested over time to deliver the most effective outcome for our clients. The starting point is always a meeting, either face to face or remotely via teleconference or phone call. Here we aim to get a good understanding of our client’s business, goals, and objectives. We then go to work and create a sitemap and wireframes to show our client’s proposed structure of the site. Next, we design visuals to show our client the design direction we will take.

Creating a website is a collaborative process, and we encourage our clients to give their feedback at each step before we begin the programming stage. Proof checking, testing, and more testing is the final stage in our web design service to ensure we deliver our clients a complete and professional website.

What type of web development services are there?

Our web design services in Sydney cover all aspects of what is required to get a website not only live, but also found through the search engines. This covers User Interface design (UI design), User Experience considerations (UX), the visual impact of the site as well as the way the message is delivered from a marketing perspective. We also provide hosting services and ongoing support and maintenance of websites after they are launched.

Should I hire a Sydney based web designer or do it myself?
Websites are a critical component of any business, so it is essential you develop a website of high calibre. We suggest hiring a professional web designer as this means all essential aspects will be included. This may not be achievable when taking on website design yourself as each aspect requires a high level of understanding and specialisation. These include: Unique design, Seamless user experience, Mobile responsiveness, Room for limitless growth , Comprehensive SEO.
How do I redesign my existing website?
Redesigning your website is an essential part of business growth. Ensuring your content is up to date and caters to your website visitors is important. The process begins with an analysis of current performance and identifying what works and what doesn’t. This may include enhancements of visuals, adding new functionalities, SEO strategies, design elements and user experience.
How much does it cost to design a website?

A Spark-built website is a complete product that leaves no loose ends. All pages are built, content added and styled so that the site is a cohesive and professional finished product. Our Sydney web design services range in price from $3500 – $5500 as an average indication. Of course, more complex sites that have special custom features will be more expensive.

What is the best platform for designing a website?

At Spark Interact, we use WordPress for our web design and development projects. WordPress enables us to develop websites to suit varying budgets, it has a large variety of plugins that allow for site growth, it has high security features, allows for successful SEO optimisation and offers excellent support. The online platform is flexible and powerful and has been made to accommodate any requirements. These are some of the many features that set WordPress apart from its competitors.

Can you help me with images and/or copy for my website?

Yes! Here at Spark we strive to help you with every aspect of your project. We have copywriting specialists that will turn simple words into compelling, industry-specific content. Our team can also provide relevant images from extensive stock resources or can organise photography services to update your current stock. Whatever your needs are, we have the knowledge and solutions to meet them.

How long does it take to develop a website?

A single page scrolling website is the fastest website build. Although it is a single page site, it has the appearance of different pages controlled by the scrolling function. This site can be built in a matter of 3 to 5 days. A multi page 5 to 7 page site takes an average of 4 weeks. And a more complex site of 15 plus pages can take up to 10 weeks.

How often should my website be updated?

Websites should be updated in conjunction with the growth of your business. As the business evolves, so does your website. This includes updating photos, services, design elements, functionalities and user experience. It is important to analyse your website in relation to your competitors to ensure it is compatible and up-to-date with industry standards. Another good indication of when to update is when digital trends evolve. Sometimes not being at the forefront of those trends can mean your website is overlooked.

What are the benefits of using WordPress as opposed to the
do-it-yourself online builders?

WordPress provides more functionality and flexibility. It is an advanced platform that allows for more unique tailoring and expression of creativity.

Do-it-yourself builders don’t let you go beyond their provided templates and can be limited when it comes to functionality. WordPress, however, combined with a solid knowledge of coding will allow you to run for free and create a website that is customised to fit your specific needs.
