How to add SEO to the Gatsby blog

Search engine optimization sites can be shown better in the search results and also helps to the search engine bots to better understand the content you are publishing.

Open graph tags are used to get the rich snippets when somebody shares your content on social media.

You can also check out Meta tags that Google understands.

Gatsby Seo-Component

create a new component called Metatags.js so that we can reuse it anytime.

Metatags.js
import React from 'react';
import Helmet from 'react-helmet'

function Metatags(props) {
    return (
        <Helmet>
         <html lang="en" />
              <title>{props.title}</title>
               <meta name='title' content= {props.title }/>
               <meta name='description' content= {props.description }/>
        </Helmet>
    )
}

export default Metatags;

In the above code, we have added title and description tags by using the react-helmet package. You can ready to use the above component if you don’t care about social media sharing.

Let’s improve the above component for the social sharing.

Metatags.js
import React from 'react';
import Helmet from 'react-helmet'


function Metatags(props) {


    const { title, description, url, pathname, thumbnail } = props


    return (
        <Helmet>
            <html lang="en" />
            <title>{title}</title>
            <meta name='title' content={title} />

            <meta name='description' content={description} />

            {pathname && <meta property='og:url' content={url + pathname} />}


            {thumbnail && <meta property='og:image' content={thumbnail} />}

            {thumbnail && <meta property=' og:image:secure_url' content={thumbnail}
            />}

            <meta property='og:description' content={description} />

            <meta property='og:image:width' content='1200' />

            <meta property='og:image:height' content='630' />

            <meta property='og:locale' content='en' />

            <meta name='twitter:title' content={title} />

            <meta name='twitter:description' content={description} />
            <meta name='twitter:card' content='summary_large_image' />

            {thumbnail && <meta name='twitter:image' content={thumbnail} />}
        </Helmet>
    )
}
export default Metatags;

Now you can get rich snippets when you share your post on twitter or facebook.

How to use this component ?

You can use it on your blog-post.js file by passing the title and other fields.

blog-post.js
   <MetaTags
        title={title}
        description={excerpt}
        thumbnail={url + thumbnail}
        url={url}
        pathname={props.location.pathname}
    />

Happy coding…
