It's difficult to have someone else do SEO for you
I am the web developer for
https://roofvents.com/ so I thought I should add my perspective on the distinction between having a website for your business, and using "Search Engine Optimization" techniques to actively move that site up to the top of the first page on Google searches...
Everyone should have some presence online. There are many options to put together a simple web page, register a domain to point to it that is easily identifiable as your business, and point to it from your social networking pages. If you can write a MS word document, you can create a web site on Wix, Squarespace, or wordpress.com. Think of it as a cross between a billboard, and a business card. It is useful to have, so when you get a call from a word-of-mouth referral or someone who saw the phone number on your truck, you can point them at the site and they'll get the intro to what you do and where you do it.
SEO is about finding a useful place to put the billboard. Sure, it's easy to put up the billboard up on that little dead-end road down the street, but no one will every see it. You want your billboard up next to the interstate, right by the bridge that goes downtown to the biggest city in your area where everyone is stuck in traffic twice a day. That's not as easy, and not cheap if you hire someone to do it.
The problem with hiring someone to do SEO for you is that they don't know your business. SEO is about the words people use to search for you. You know what those words are, your "SEO Expert" doesn't. So if you're going to have any sort of web presence, you may as well use words on your site that will get you found by people who need what you do, in your local area. Hiring someone to "do SEO" for your web site means hiring someone to write your website. Write pages, write blogs, encourage linking to your site (if they ask you to PAY for links, RUN AWAY!) and create a structure for your site that is optimized for keywords that people are searching for. Any way you look at it, and regardless of how much money you pay them, it will TAKE YOUR TIME to explain to them what you do, how it is described, other ways of putting it, and the kinds of questions you answer every day.
So my advice is, do the web site yourself, and write a blog every week about something that you do. How do you know what to write? Search for a roofer on Google. Search for a roofer on Bing. What sites come up in the "organic" searches 1st, 2nd, and 3rd. Look at those sites. Look at the words they use. Note how easy the site is to use. To have your site rank in the same ballpark, you should be using many of those same words.
Google changes the game constantly. SEOs don't know your business, but they tend to learn tricks. But the tricks that worked on the web 5 years ago no longer worked 3 years ago. What worked 2 years ago didn't work anymore last year, and what worked six months may have been changed already. Google has advice about this. Forget about tricks. MAKE YOUR WEBSITE USEFUL TO YOUR CUSTOMERS. Even as SEOs figure out how Google's computer algorithms work, Google is using their most sophisticated Artificial Intelligence to understand what customers actually need. So skip the middleman, save $500/week, and write honestly about what you do on a simple web page, every week.
I hope this helps.
