      Web Development Review from Pete Herbst

      We worked with Cidersoft to port our main website from Drupal 7 over to Next.js and a custom CMS backend. This was a heavy lift and they were instrumental in helping us accomplish the website launch on the new tech stack in the timeline we were looking for. They are responsive to changes in requirements and goals while also providing good feedback if they know of a better, more appropriate way of doing things. Pleasant to work with, good people. Overall, big thumbs up, would recommend.

Frequently Asked Questions

What is responsive web design?

Responsive web design is a web design method that allows a website to dynamically adapt how it’s displayed on different devices, considering the user’s platform and screen size. This way, web developers and designers can build a single responsive version of a website instead of multiple ones for different devices.  

When done right, responsive web design provides a seamless user experience (UX), improved load times, and, in turn, higher click-through rates (CTR) and better search engine optimization (SEO).  

If you need responsive web design services, you can: 

  • Hire a professional responsive web design agency and outsource your project 
  • Develop your own project using responsive website builder software like:  
    • Wix,  
    • Weebly,  
    • Squarespace,  
    • Webflow, etc. 
  • Hire freelance web designers 
  • Hire in-house responsive web designers 

What companies provide responsive web design services?

Typically, most web design companies also provide responsive web design services to ensure seamless user experiences across different devices.  

Web design companies that specialize in responsive design help create responsive websites, web applications, games, and other types of web content. These companies also offer mobile SEO and UX services including on-page and off-page SEO, tag optimization, URL optimization, technical SEO, content optimization, sitemaps, wireframing, user personas, user journeys, UX design, etc. 

How much does responsive web design cost?

The price of responsive web design agency services can go anywhere from $2,000 to $50,000 per website. The costs depend on various factors like: 

  • Size: number of website pages, page templates, pieces of content, media, etc. 
  • Complexity: the complexity of navigation, types of visual features, third-party program integration 
  • Functionality: whether there will be booking and scheduling services, customer portals, etc. 

Here are some examples of typical price ranges for responsive web design and maintenance projects: 

Website type Total design cost  Annual maintenance cost 
Small business website $2,000 - $10,000 $400 - $1,200 
Corporate website $10,000 - $30,000 $2,000 - $15,000 
eCommerce website $5,000 - $50,000 $15,000 - $30,000 
Database-driven website $6,000 - $75,000 $30,000 - $60,000 

The top 50 responsive web design companies on DesignRush charge an average of $83.5/hour. Roughly 25.20% of the responsive website design companies on DesignRush accept projects with a minimum budget of less than $1,000, while 3.70% have a $50,000+ minimum budget. 

Why should you hire a company that specializes in responsive web design?

You should hire a responsive web design agency because of the following benefits: 

1. Better user experience 

According to Google research, 53% of mobile users leave a page that takes longer than three seconds to load. A responsive web design company will optimize your website for fast loading speed, among other things, improving the user experience by ensuring that the content remains accessible and readable across all devices. 

2. Improved search engine rankings  

Websites that are mobile-friendly, which is the main draw of responsive web design, get higher search engine rankings. This way, you increase the visibility of your website and attract more traffic. 

3. Sales optimization 

79% of consumers disappointed with the website’s performance are less likely to make a purchase from the same site again. By improving your website design, you are increasing the chances of getting recurring customers. 

4. Responsive website design expertise 

Experienced developers with a lot of responsive projects under their belt typically deliver higher quality work. 

5. Faster results 

When hiring a responsive web design agency, you don't need to spend time and resources to recruit and train internal web developers. 

Here is an example of a successful project by a responsive web design company called Big Drop: a client needed to modernize its visual identity with a refreshed website. Big Drop provided intuitive user journeys, clean UI, and an information architecture strategy to enhance the client's digital presence.  

After implementing website changes, the clients saw a 15% increase in conversion, 9% increase in page load speed, and 17% increase in on-site engagement. 

How to choose the best companies that provide responsive web design?

You can choose the best responsive web design companies by following these steps: 

  1. Define project scope: Decide on website structure, number of pages, features, and functionality. 
  2. Set project requirements: Make a checklist of goals and the means to achieve them (e.g., deliverables list, timeline, communication guidelines, preferred technologies, etc.). 
  3. Set a budget: Look for the best talent in a range you can afford. If you have a small budget, try expanding your search to countries with more affordable prices. 
  4. Inquire about experience: Ask the responsive website design company for a portfolio and similar project examples from your industry.  
  5. Check credentials: Ask for certifications in common web development technologies like HTML and CSS. 
  6. Choose the development approach: Depending on the project, the company should offer an Agile, Waterfall, or hybrid development methodology and tell you about the benefits of each. 
  7. Send a request for proposal (RFP): An RFP contains the project introduction and scope, technical requirements, evaluation criteria, budget, and submission guidelines. Select up to five responsive web design companies and send them an RFP. 
  8. Review RFPs: Go through each proposal, compare results, and interview your shortlisted companies. 
  9. Make a decision: Pick a responsive website agency based on your top criteria and examine the contract before signing.
