SEO is not the same on google page as it is on my main web page

I recently published my portfolio a week ago. Today I looked and seems like there are impressions on Google search and I found my website on there finally. As the title states, my SEO on my main page is different that what it is on Google. Is this a common thing or am I doing something wrong?


Here is my site Read-Only: LINK
(how to share your site Read-Only link)

If you read the information Google provides at Webmaster Central you will learn that Google’s algo makes the decisions about what to show. It takes hints from content on the page and meta tags and other factors. It’s driving.

I see, thank you. Still learning this kind of thing.
