Website 'tuning' and SEO

First step here would be to register and log onto the Google Search Console. Google will sometimes find something that it does not like for some reason, and creates a "manual penalty".  These are listed. You really need to know if you have anything listed there.

As Mal suggested, before you do anything else...

1) Ensure your site is actually verified.

This means... www + bare host, so https://www.foo.com + https://foo.com

2) Fix every single Google Search Console nag, no matter how small.

3) Do a Google search of site:foo.com to ensure your site links are making it all the way from your sitemap through the GoogleBot spider into the index.

All this you can do yourself, rather than hiring so called Experts.

4) After all Google Search Console nags fixed + search site:foo.com returns correct link count (should match Google Search Console indexed page count... roughly...) then proceed to other considerations for improving your SEO.

Mobile-friendlyness? Is your new website responsive to multiple view-ports AKA morphs for different resolutions via CSS?

Domain/Host age?: Has your domain name been recently transferred to a new host or has ownership of your domain changed recently?

Bad SEO?: Did your SEO expert/developer use "black hat" tactics like link farms (placing hundreds of links of your site somewhere), cloaking (duplicate or funnel sites like yours that link/redirect to your site), new phone numbers (to track callers), new domains, keyword spamming, or similar harmful strategies?

Dead Links?: Did your SEO expert/developer properly redirect all of your site's old links?

HTTPS?: Does your site have an up-to-date TLS/SSL certificate? Or is your site non-secure HTTP?

New website is not mobile friendly.
Domain name has not changed or transferred to a new host.
Hmmm.... no SEO expert, a web developer.   Running FoxReviewer shows several development issues that were overlooked.
No dead links.
Yes, I believe the TLS/SSL certificate is up to date.

New website is not mobile friendly.

 
Google actively penalizes for not having a responsive website; namely due to a majority of web devices now being comprised of smartphones and tablets, opposed to desktops and laptops.

Such as? The more info the better.

No dead links.

Are you sure old links aren't dead? This is a very common oversight. The new links might be working but old URL links to products/services/subdirectories/etc can be killed by development if the original directory hierarchy isn't preserved or, if changed, proper permanent or temporary redirects aren't defined.

Yes, I believe the TLS/SSL certificate is up to date.

In your browser, does the website show up as http--your site address-- or https--your site address--? Another follow up question: can you view your site from http--your site address-- or does your site properly force https AKA redirect to https--your site address--?

Which subfolder on our web server do I copy Google's verify file for getting verified for the Google Search Console?

Here is the FoxReviewer Report for our website.

For the HTML file upload method, usually Google will make you post the file in the folder that reflects your site's "public" root directory sometimes this is "/" or /public_html/" which corresponds to where your site's main index page is (server configuration varies, knowing where your index.php, index.html, or other index file is located is typically where your public root folder is)

Thank you.   I will try that.

One of the stark mistakes is having NO TITLE on the pages. This is the main line of text Google uses to compare keywords users search for to.

You will want a unique title for each page.

Having no meta tags is less important; however, these help hint to google what the page is about and is a factor. At a minimum, use the DESCRIPTION and KEYWORD name subtypes to help describe each page.

Your site is confirmed to be HTTP non-secure. No TLS/SSL is in place.

Your site is responsive, try to view it in a smaller window or cell phone; see how it morphs?

There are broken links and most likely dead links from not redirecting old links to the new correlated locations.

404 errors without redirects, not good either, e.g. try to go to a non-existent directory http--your site adress--/contact

I recommend to NOT resubmit to Google until everything is fixed.

kk    Ownership has now been verified with Google Search Console.

Also, I can load http://xxxx_website.com but not https://xxxx_website.com

As soon as I get our visibility up, I'll have to find someone to setup a 'mobile' version of our site.

No dead links.   Just checked them.   Not many to check :)

Our website only shows up on http://xxxxwebsite.com       does not get redirected to https://xxxxwebsite.com
https://xxxxwebsite.com comes back with an error that 'Your connection is not secure.'

NerdofTech -- I have a beginning level of experience with Adobe Dreamweaver, but am led to believe that our website cannot be edited with this software.   Hence.... I need to find someone who can 'tweak' the website to get it to work at it's optimum.  ;)

I clicked on every link I could find, but didn't get any '404's, and it seemed to go where I wanted.    Hmmmm.....  
Are you interested in fixing this for us?

HTTPS isn't a requirement but it is a factor in how Google ranks you now. It also legitimizes your ownership of the domain and secures your client's connection to your site (the factor that Google is most concerned with).

You mentioned that dreamweaver isn't viable to edit the site.

Does it have a CMS like wordpress or a web builder/SaaS like Wix where you must login to your site's admin panel to change things on your site?

I see that your CSS responsive framework is Twitter Bootstrap (common).

The more info you can provide the better, regarding how your site and server are configured.

Yes, you do have the option to hire an expert from this site, as some of us, like I, have "Live" links in their profile for 1-on-1 help; that, or an Experts Exchange "Gig" can be created to have experts bid on the task(s) you want to be completed.

DIY is another option, where we can troubleshoot each element here.

I know what our web developer didn't use a web builder/SaaS like Wix .... there were no instructions on logging into our site as an admin to make changes to the website.....    At some point I had asked if I could use DreamWeaver to make 'small' changes to the website and her response was that DreamWeaver wouldn't work.   I always thought I'd have time to ask her about it......   she is no longer reachable.  

Although we can get to our website from a SmartPhone... the 'Take A Payment' homeowner portal doesn't load properly.   I'm sure that the 'Submit New File' from the managers portal probably wouldn't work either.   This would be a separate project though.... our primary concern at the moment is becoming 'visible'.

Where would I create a 'Gig' request for bids?   Unless you would like to take this on?  :)

Regarding the non-redirecting 404 go to any subdirectory that does not exist e.g.

http --your site--/doesnotexist/

It will throw a 404 error of course, however, you will want your 404's to redirect to your index page or to a friendlier 404 error page; especially if you don't know which old links might be dead from your previous site heirarchy.

Speaking of web hierarchy, it is recommended to have a sitemap on file with Google as well and at your home directory "/sitemap.xml", once you have everything fixed.

My apology, it looks like EE no longer offers 'Gigs'. Live help is still available via expert profiles.

Do you have ownership and credentials for the hosting account? Are you self-hosting? More information about the server is needed.

We are self hosting.   Our web server is located in-house on a Dell server running Server 2016 Standard.    Looks like the website files are *.aspx rather than *.html.    I have access to our GoDaddy account which contains the SSL certificates we purchased.   I had assumed they were installed on our web server.

I checked with Experts Exchange support and in lieu of Gigs, experts are now allowed to exchange direct contact info via profile "Message" buttons.

I don't see why the .aspx can't be altered by Dreamweaver. Personally, I would use a plain text editor like Notepadd++ to open/edit the files to keep the code the same without add-on code Dreamweaver will sometimes add. ASPX files are normally found on Windows servers. They are files with HTML and added server-side coding (usually a form of modern VB) opposed to .php (PHP) found commonly on *nix servers.
