You must have seen the adverts (huge budgets), sites like WIX have been spending on advertising (mostly YOUTUBE) and have been tempted to create a WIX website, Regardless of the provider WIX, Squarespace, site123.com etc some things remain the same. And our experience of delivering websites will help you in creating your own.
Of course I value my clients and I don't want to be unkind but without your deliverables how do you want to have an awesome website! These are very helpful if you are creating your own website too. writing for your own business is hard.
What should a client deliver better to get a better website?
Every single piece of content should be accessible with as few clicks as possible hopefully just 3. But as important is the way in which people understand your offering and how the menu serves to show and underline this. If you mess with the menu you can also mess with your url's which doesn't allow google time to learn what your website is about in short it's bad (really bad) for SEO.
If you have mapped out your site correctly as stated earlier you shouldn't need to have issues with changing url's. If you do decide to split content into two different pages then do it, but not after 2 months of the site being live. It is often helpful to block search robots until you are fully happy with the website. But you might loose some valuable crawl time if you do that too. So again a nod back to getting the pages and map right first time.
There are GZIP compression optimisations, image optimisations as a minimum, beyond this cache pages and reduce calls to the server for content that doesn't change. We are getting a bit technical if we carry on. I just wanted to offer this as something you can learn and do some DIY with. Please try and make your site https which is encrypted pages. Of course some of the paid site builders do this for you and that can be very good news.
Try not to install too many plugins unless you really need them. Plugins offer useful functions but also can leave you with a headache when the CMS updates or the plugin updates. For this we offer a service to get your website up to date and offer a cheap plan to keep your site secure and running smoothly.
