Core Web Vitals:

If you want your website to rank well on Google, you need to do more than just add keywords. You also have to give people a great user experience. That’s where Core Web Vitals come in.

These are a set of important performance metrics that Google uses to measure how your site behaves for real users — especially on mobile.

What Are Core Web Vitals?

Generally, Core Web Vitals are three key performance indicators that focuses on as shown below:

1. It checks that How much faster your content is loading

2. It checks that How soon users can interact with your page

3. Also it checks that How stable your page looks while loading

What is a Sitemap?

In simple terms a sitemap contains a list of all the important pages on your website. It tells search engines like Google and Bing which pages exist, how to find them, and how often they’re updated.

It is like a roadmap for all the search engines. It helps the search engines to  crawl and index your site faster and more efficiently.

There Are Two Main Types:

  1. XML Sitemap – For search engines
  2. HTML Sitemap – For human visitors (optional)

 

How to Create a Sitemap (Step-by-Step)

There are several easy ways to create a sitemap — even if you’re not technical.

Method 1: Use a Sitemap Generator Tool (Manual Site)

If your website is built without a CMS (like a hand-coded HTML site), use a free sitemap generator.

Example Tool:

 Steps:

  1. Go to the website
  2. Enter your domain
  3. Click “Start”
  4. Now it will start crawling your site and generate an XML file
  5. Download sitemap.xml
  6. Upload the file to your website’s root folder (e.g., www.example.com/sitemap.xml)

Method 2: Generate Sitemap in WordPress (Automatic)

If you’re using WordPress, sitemap generation is super easy.

Use SEO Plugins:

  • Yoast SEO
  • Rank Math
  • All in One SEO Pack

Example with Yoast:

  1. Install and activate Yoast SEO
  2. Go to: SEO → General → Features
  3. Make sure XML Sitemaps is turned ON
  4. Visit your sitemap at:
    www.yoursite.com/sitemap_index.xml

This link is automatically updated as you add or remove pages/posts.

 

URL redirecting techniques.

When you change a webpage URL or move content to a new location, you don’t want to lose visitors or search engine rankings. That’s where URL redirection comes in.

A redirect tells browsers and search engines where to go when a page has moved.

Common Redirect Types

1. 301 Redirect (Permanent)

Inform search engines the page have been moved for good. It also passes most of the SEO value (link juice) to the new page.
Example:
You changed
https://example.com/old-blog-post
to
https://example.com/new-blog-post
A 301 redirect will send both users and Google to the new URL.
How to Do It (Apache server – .htaccess):

Redirect 301 /old-blog-post https://example.com/new-blog-post

2. 302 Redirect (Temporary)

Used when you want to move a page temporarily — like during maintenance or A/B testing.

Example:
You’re testing a new page, so you will temporarily redirect it
/product-a → /product-a-test

Use 302 redirect only if you plan to bring the original page back.

Tools and Plugins to Set Redirects (No Coding)

If your site runs on WordPress:

Use plugins like Redirection, Yoast Premium, or Rank Math.

What is a robots.txt File?

The robots.txt file is a small text file placed in the root folder of your website. It tells search engine crawlers like Googlebot which pages or folders they are allowed (or not allowed) to visit.

It’s basically like giving search engines a set of instructions.

Why it is important?

It helps you control what gets indexed

Keeps search engines out of unimportant or sensitive areas (like admin pages, login pages)

Where to Place It?

Your robots.txt file should be located at:

https://www.example.com/robots.txt

 

Example 1: Allow Everything

User-agent: *
Disallow:

This tells search engines they can crawl your entire site.

 

Example 2: Block a Folder (like /admin)

User-agent: *

Disallow: /admin/

 

Now, search engines will not crawl any pages inside the /admin/ folder.

 

Example 3: Block a Specific Page

User-agent: *

Disallow: /private-page.html

 

Example 4: Allow All But Block Images

User-agent: Googlebot-Image

Disallow: /
