A question is asked, what is the right expression for a company that concerns itself with website construction. Is it just the mentioned or with the true mission it must have?
Businesses many times search for companies based on the construction cost, meaning they look for a presence in the web and they ignore the result of that presence.

The purpose of constructing a website for the majority of businesses is the increase of sales excluding conventional ways they already use, like their shops. Only a few businesses create a website just to be in the internet. So the first concern of every company that invests money, less or much, for creating a website, must be the sales it will achieve through that website and not if the website that will be pretty and well design is cheap as well.

a) The first concern in constructing your website is the friendliness of your website towards search engines, which will bring results, visits
b) The second concern is that the website must be easy to use, in order to increase sales, to make the visitors not wanting to leave tired from it by searching their needed information or  product in a complex environment.
c) The third concern is that the website must be designed to be simple and pleasant for the user, with not many intense colors, in a minimal environment, were the client's attention goes to the information or product and not to the graphics. Nobody enters your website to see how pretty it is, but because he needs a certain service or product.
d) The fourth concern is not to have music. Music is forbidden in your website, unless you are a singer or a record company. Music is repulsive for the user and creates a larger bounce rate. It also violates the user privacy, as he might be in a working environment and by visiting the certain website, he wouldn't want to be heard by the rest of the workplace. Music is not a necessary part of your website, nor an attractive one.
e) The fifth concern you must have when having your website created is to have advertising banners in your website, moving images and products, but not in an excessive matter, since it can become tiring and disturbing for the user.

Based on the information above for your website, you must choose your website manufacturer with the right criteria.
For the right choice you must, first of all, set the criteria yourself:

a) I want a website constructor to make me a profitable website.
b) I want a website constructor who has many years of experience in this field.
c) I want a website constructor that persuades me by giving result and not cheap price.
d) I want a website constructor that gives me many and different solutions.
e) I want a website constructor that is an organized company and can support me after the creation of the website.
f) I want a website constructor that can solve all my questions and explains the difference between a cheap service and an expensive one.
g) I want to avoid a website constructor who, as his first argument uses his low price. Because he who offers a low price has not in mind that he actually provides the most expensive service to the business.

The goal of every company is to invest and gain more than that investment. If they suggest you invest 1000 euro to gain 5000 euro and someone else 100 euro to no certainty in success, the most effective choice is the first offer.
Because businesses are made to invest and gain money. In every investment there is a logical judgment. By investing 100 euro nobody can target profits of 10.000 euro and above, because by doing that it is not an investment it is gambling or luck!
The target of an investment is to multiply your profit, so the investment must be important in order for it to offer you the needed services and results.

The website constructor is your internet salesman, if you want someone to create a website for you for 100 euro, it is like hiring a salesman for a 100 euro wage. It is almost certain you will not find that salesman and , if you do, he will be totally irrelevant with the business of sales.
So, in order to achieve the creation of an effective website, you must deal with the constructing party as you would with your salesperson, you must motivate.

Nobody is willing to work for free, a website that can bring result needs investment in time and if the manufacturer is not motivated for a certain gain from this project, he will not be serious in this cooperation.
Nevertheless, motivating someone is not costly at ell, you just give him a promise for gains from future profits.

Make the website constructor your partner, and give him a position between you and your important partners. In this manner, he will give all the needed attention to your website as well.

Good luck!
