Its so so…
1)I check out your post: “How to Use a Electric Knife Sharpener”
For God sakes man, Its a tutorial! add some images! Even if its a simple as 1, 2, 3….people need to see to understand!
2) by looking at your site, looks like you are trying to sell something. THEN SELL IT! if you were a knife sale man that went door to door, you wouldn’t just read off the instructions what it can do, you would PROVE it can do it. So add videos/images of PROVING it! then give more info in the content.
3) ask yourself, if you were surfing the Internet for your topic, would you read this site, or would you hit the back button? Find out what readers in your nitch are looking for, and provide it!
I am just providing what I believe your site needs. Hope this helps!
