How to generate HTML meta tags for SEO optimization in Go?

To generate HTML meta tags for SEO optimization in Go, you can make use of the html/template package. Here's an example implementation:

Import the necessary packages:

import (
    "html/template"
    "os"
)

Create a struct to represent the metadata:

type Metadata struct {
    Title       string
    Description string
    Keywords    []string
}

Create a function to generate the HTML meta tags:

func GenerateMetaTags(metadata Metadata) string {
    t := template.Must(template.New("meta").Parse(`
        <meta name="title" content="{{.Title}}">
        <meta name="description" content="{{.Description}}">
        {{range .Keywords}}
            <meta name="keywords" content="{{.}}">
        {{end}}
    `))

    var result strings.Builder
    err := t.Execute(&result, metadata)
    if err != nil {
        // Handle error
        return ""
    }

    return result.String()
}

Build and test the function:

func main() {
    metadata := Metadata{
        Title:       "Example Page",
        Description: "This is an example page.",
        Keywords:    []string{"example", "page", "SEO"},
    }

    metaTags := GenerateMetaTags(metadata)
    fmt.Println(metaTags)
}

This implementation uses the html/template package to define a template for the meta tags. The GenerateMetaTags function takes the metadata as input, executes the template, and returns the generated HTML meta tags as a string. You can customize the template to include any additional meta tags or attributes as per your requirements.
