Default meta description
To activate it, go to System> Configuration> Design> Design> HTML Head> Default description and press “Enter.” Magento changes the status of all pages, which are now considered unique. Translated pages and duplicate URLs. There are three languages supported on the company's site. In case the product is xyz.com/product.html for English, different URLs should be used by other languages such as German and Spanish. This is true for all pages in a website of electronic commerce under Magento.
Overlook rel = “alternate” hreflang = “X”
It is used to join pages with similar content in different languages. Never use canonical URLs to translate pages. Another tool can be used, “x-hreflang default” for landing on different language pages. Remember to link translated pages to each other. This can be activated with country flag icons or direct language links, such as “change to English.”
Deleting pages/Changing URLs without activating” 201 Redirect”
When deleted pages are redirected and URL changes are not made correctly, there is a 404 error. For search engines, this is an acceptable error as some URLs may lead to a 404 page. On the other hand, a 404 error tends to make users feel uncomfortable. Removing all 404 redirects is the optimal solution to counter this. To do this, go to System > Configuration > Catalog > Create Permanent for unused URLs.
Neglecting image optimization
Magento does not change the name of the product image or its tag. Images can bring traffic to the site via search engines. Therefore, SEO-optimized image names and alternative tags (alt tags) are required to achieve this goal.
Magento XML Sitemap
The default Magento XML Sitemap is a bit simplistic; it only consists of products and pages, no photos. An XML sitemap upgrade allows for proper indexing and reindexing of store pages. Double check the viability of the content before sending it to Google Webmaster Tools. A common error is submitting a site map containing product samples.
Overlooking Rich Snippets
The regular Magento platform does not have options for producing rich snippets. In reality, rich snippets help to give additional exposure and visibility to your website. Also, keep Google Analytics in mind; rich snippets produce more clicks. Applying rich snippets is cost effective and will get you more traffic, sales, and clicks.
Good optimization.
