Ok, just remember that you asked for advice haha.....
- I would stick with a uniform size for your featured images instead of random sizes. 800x500 is good.
- Spend a lot of time on keyword research and optimizing your content, if you're doing less link building you'll need to make up for it with incredible on-page.
- Your article titles lead me to believe you're aiming to promote them on social media, if that's the case then you'll want to find less stock-photo looking featured images, and instead find images that will inspire curiosity and clicks. If that's not the case, circle back to the KW research, find good keywords, use them in your titles.
- The formatting of your content is bad, you aren't using any headers, it's just walls of text. No images in your posts, no headers, it's very poor on-page and very poor readability/user experience. Take your list items in your list articles, and take the bold part, and turn that into an H2. It'll look much better, and having keywords in your headers can be beneficial. Put in the effort to add images for each list item, too.
- Some of your titles are written in all caps and other ones aren't, it looks kind of weird.
- Get yourself a free SSL certificate if you don't want to pay for one, and switch to https instead of http.
- Use your target keywords for each article in the image titles, instead of something like "foggy-545838_orig.jpg", just another element of basic on-page optimization.
- Hire somebody to design a logo for you that isn't from Fiverr if you're serious about this brand, or just go with a nice font and make a simple one yourself. The current one looks cheap and unprofessional the way it is now, it will hurt your trust with readers.
- Your homepage is loading 1.2mb of images, you should be able to bring that down with some optimization and improve your speed score.
- Think about better hosting, your time to first byte is almost an entire second. 1&1 is basement-tier when it comes to hosting, evidenced by an inner-page that's only 602.2 KB taking 1.7 seconds to load. Rule of thumb is just avoid any of the hosts that get recommended on the first page when you google "best hosting" because those are all the ones that offer the highest commissions to their affiliates, not the ones that provide the best service. Anyone who recommends 1&1, hostgator, godaddy hosting, etc - is just flat out lying to you.
- Those share buttons are slowing down your site too with a bunch of extra requests. You can make custom buttons for FB, Twitter, Pinterest that won't slow your site down as much, and the rest of those are probably not even worth including for the tiny, tiny % of your visitors that will click any of them at all. Most of the sharing will happen via the social network side of things, not from the page itself. You're better off having a faster loading site than getting 1 out of every 1500 to click one of those buttons.
Good luck!
