CheckSite WordPress Website & SEO

Almost anyone can set up a WordPress website. However,that doesn’t mean you should launch it blindly. If you want your site to get off on the right foot, you need to plan ahead, develop a concept, think about the elements you want to include, decide on the type of content you want to publish, and more. Once these elements are clear in your head, you can get started on the technical aspects. This means procuring a domain, finding a web host, setting up WordPress, and myriad other steps.

Do you have any questions about how to launch a website?
Let’s talk about them in the comments section below!

Sundance Pressure Cleaning Niagara

Les is hands down the best man in the business when it comes to web-site development and SEO - he came highly recommended and we have never looked back.

After spending thousand of dollars on Facebook and Instagram advertising we quickly stopped throwing our money out the window after seeing the results we got after Les took over.

If you want the best - stop looking and wasting your money on what doesn't work and start listening to Les from CheckSite - you will never regret it and get ready to get busy because your phone will not stop ringing!


Hey Les, I just wanted to reach out and express my gratitude to you. My website is consistently coming out on the top of Google searches. Whatever you are doing is working fabulously 👍

Ok, Les is a bit 'off the wall;' but in a nice way. lol He really is a great guy, knowledgeable, understands your business and is goal oriented... and for those reasons, has been taking care of our sites for many years now as our full time IT department. By the time the big players 'issue you a repair ticket', Les has it done, done right and under budget. When you find a great programmer like Les, you'll want to keep him. As they say... Les, you da man!
