I'm trying to get my site to rank on Google Search. I've searched the whole web, literarily on how to make this work. I see that when I search, it doesn't use the description meta tag. When I look at my source code it uses both og:description and description, does this cause any type of issue? Should it be de-duplicated as many tutorials suggests?
<meta name="description" content="ELDE Cosmetics creates natural, fun and minimalistic skin care products for all skin types. Free from fragrance, essential oils, parabens.">
<meta name="keywords" content="Beauty, skincare, makeup, fragrance, perfume" />
<link rel="canonical" href="https://eldecosmetics.com/">
<meta name="viewport" content="width=device-width,initial-scale=1">
<meta property="og:type" content="website">
<meta property="og:title" content="ELDE Cosmetics — Natural & Organic Skin Care">
<meta property="og:description" content="ELDE Cosmetics creates natural, fun and minimalistic skin care products for all skin types. Free from fragrance, essential oils, parabens.">
<meta property="og:url" content="https://eldecosmetics.com/">
<meta property="og:site_name" content="ELDE">
Sorry to disappoint you, but these two tags do actually very marginally (if at all) affect SEO. They are mainly used for showing short descriptions of your page, if your site is linked on other sites. description
may (you have no certainty) be (partially) used by search-engines, while og:description
may be used by social media networks like facebook.
edit: using both (with useful content) won't hurt.
To combine them (Schema and OGP) see this and this SO posts.
