Just stumbled across this thread. I actually am part of a digital agency so I can give you my perspective from a conversion standpoint.

What @Debiandog said makes sense - as to what is the purpose of the website. Currently it looks like just a landing page or a small microsite - but what real action do you want someone to take once they get there. Do you want them to pick up the phone and call you? Fill our the order form? These are called "goals" in Internet Marketing lingo.

So the first thing I would do is install Google Analytics on the website. It is free to do - and basically it will tell you who came to your website, how they found you, how long did they stay, where did they go, where did they leave etc.

You can learn more here: Google Analytics Official Website – Web Analytics & Reporting

I would suspect now it wouldn't tell you much because the site itself is not designed in a way to drive traffic and is probably not getting much traffic - but like I said regardless of how little traffic you may or may not be receiving - it is FREE to put on your website and it can tell you a lot about what people do on your website.

From an SEO perspective - which basically means the likelihood of people finding your website naturally in the search engines is not going to happen. So if someone were to go to Google and search for things like:

Aftermarket Car Parts Orlando
Car Parts Orlando
etc.

There is a free tool called Google Keyword Planner in which you can plug these type of keywords in and Google will actually TELL you how many people are searching for these phrases per month. This will give you an idea of what people are searching for and how, and then it is important to properly optimize your website so that when people search for example in Google, your website appears on page 1. Ideally you want to be on the top 5 results or in the MAP results.

I mean your website doesn't even come up if people search for your company name.
Go into Google and search for nugen automotive

I mean you will notice your FB page, you will even notice this forum, but your website should actually be ranking #1 in Google for its own branded name.

The most BASIC thing you can do is define your Title and Description Tags on your pages. You can do this in the backend of your Wordpress website - and basically this is the first snippet that people will see when they look at a result in Google. To give you an idea of what Google will show in the even that your website ever does come up in Google, here is how your site and pages will get displayed.

You will note only 3 pages come up - well that is because that is all your website currently has, but you will notice that the Title and Description Google is using for your pages doesn't actually best describe the page or what your company does.

You mention your eStore is in the process of being built. Are you guys using an agency to do the work or doing it yourselves? eCommerce can get very complicated - and I mean there are platforms that can help you, most people on Wordpress use WooCommerce or some even use Shopify. This way you dont have to worry about being PCI Compliant and getting sercurity certificates and all that other jazz.

LOL hopefully I am not speaking a whole different language to you.

I mean really you have to look at your website as an investment, and most people will search your company and do their homework before ultimately making the decision if they will do business with you. I mean there are some exceptions but this is generally the case. So you want to make sure your website actually reflects your brand and quality of work. I would honestly advise you work with an agency to get this done.

I mean the cost of a website can range - but honestly what you pay for is what you get.

You can get a free website using GoDaddy or a free Wordpress theme and try to build it out yourself, or you can pay $500, $5000, $50k etc.

Obviously it depends on your budget, your needs, what functionality you need versus want etc.

If you are shopping around - you are probably looking at a cost around the $2500 mark for a descent looking website. IF you wish to add eCommerce, the cost would then depend on how many products etc you have as that can make costs fluctuate.

I mean we have built all sorts of websites , from small to large.

We just recently launched this one - Best BBQ Grill, Best Barbeques, Built In Gas BBQ Grills and it still needs work but like I said, its not just about having a good looking website, or the best product at the best price ... if no one knows you exist online, your offer doesnt mean much. This is why doing internet marketing such as PPC, SEO, Social Media, Display Ads etc are so important.

Anyways I did a webinar talking to businesses about how they can leverage the web to drive traffic and in foot store traffic etc - its a bit long but I mean if you are interested in learning more about this stuff I would advise you watch below. And even if you dont plan on doing this yourself, the more knowledgeable you are, the better off you will be hiring someone to do the work for you correctly.
