In this day and age it can seem almost impossible to get a website set up yourself but thanks to free hosts like webstarts.com and other sites like Blogger and Wordpress you can easily get started for free and then upgrade your account when your ready.
An internet business may seem like a great idea to most but the chances of you becoming the next Mark Zuckerberg are very slim unless you understand how to get a business up and running and for that you need something very simple and easy.......its called ADVERTISING.
Advertising is the most important part of any business, it drives all sales and marketing and is likely one of the areas you'll spend the most amount of your business capital on, in short you never want to underestimate the power of advertising, this includes doing things like Facebook ads, Google ads and even setting up special deals with website to buy advertising direct - whatever you need to do in order to get your products, brand and business noticed infront of your core audience that buy your products.
Advertising is an artform in my opinion but thankfully there are many companies who will do the hard work for you and all you have to do is get a good brief and have a meeting with them to discuss budgets and other requirements, most firms are very flexible when it comes to making sure the work stays within set limits for time and money reasons, they understand that not all clients are multi millionaires with a national reach, however it's important to realize you will need to have some budget for ads if you want to see a decent ROI.
Investing in online advertising has been one of the corner stones for success for many new firms, everyone goes online to buy things these days and you can see business like Amazon are making a small fortune from being the dominant retailer in the UK - you can even use your budget to advertise your products on the official Amazon site who now let retailers do so and are rapidly becoming one of the largest advertising platforms in the UK with reports suggesting a 60% growth this quarter (link).
Of course if you simply don't have the time to undertake this huge task then it's time to focus on working ON your business instead of IN your business - in short......leave it up to the professionals, firms like OTB (found at https://www.outsidethebox.co.uk/) have worked with big brands before and understand the importance of core concepts like ROI, working within the clients budget and of course have knowledge of creative advertising.
You can also turn to other firms and maybe try a local search so that you can sit down with a firm face to face, these meetings are often key to getting on the same page with the advertising company and getting a better grip of what they need from you and what you expect from them, it's best to meet with a few firms if you can because they all vary in price range and time scale.
