Hate to Say It. But I'm Losing Hope Here. A 10 Year WA member Still In the Red

I'm pretty frustrated to say this.. but I'm about ready to throw in the towel. I've thrown everything I've got at my site and the traffic hasn't budged. The site was launched in 2011 so it is an aged domain, almost 70 posts or original content, including a massive content push by me late last year into early this year...

The site did well around year 2-3, then fell off when it went dormant as life caught up to me. I've spent the last year putting countless hours into it, exhausting every SEO strategy I know and nothing. For a "well established" site, I'm only getting 10-15 visits a day, and only ~5-10 of those from organic.

At this point my site has been bleeding money for years, with my WA membership costing 300/yr... My theme is 200/yr (will likely be cancelling that first)....A few premium plugins to keep the site speed up.. And I am currently not making any income.

My site's been reviewed in Jay's hot seat twice, both times I've taken all of his advice to heart and the changes made no difference to my site's search performance.

I know as well as anyone that SEO is a marathon and not a sprint... But damn it am I tired and losing all steam.

I've put tons of work into generating unique, helpful diagrams and images, as I have a background in graphic design & photography. Work I don't see really any of my competition doing. Thought this might help but its netted 0 new traffic from any sources.

I was so determined to make this year the year I turn the site around...

Sorry to be a downer...
