Yes, page speed is an important factor for SEO ranking. Google has confirmed that page speed is a ranking signal for both desktop and mobile searches. This means that faster loading pages are more likely to rank higher in search results pages (SERPs).

There are a few reasons why page speed is important for SEO. First, Google wants to provide users with the best possible search experience. This means delivering results that are relevant and useful, and that load quickly. Second, page speed is a signal of the quality of a website. A website that loads quickly is more likely to be well-maintained and updated regularly.

There are a number of things you can do to improve your page speed, such as:

Optimize your images. Images are often one of the biggest culprits when it comes to slow page loading times. Make sure to compress your images and use the right file format.

Minify your code. Minifying your code can remove unnecessary whitespace and comments, which can make your pages load faster.

Use a caching plugin. Caching plugins store static copies of your pages, which can be served to users more quickly than dynamic pages.

Choose a good web hosting provider. A good web hosting provider will have servers that are fast and reliable.

You can use a variety of tools to test your page speed, such as Google PageSpeed Insights and GTmetrix. These tools will give you a score for your page speed and provide recommendations for improvement.

Improving your page speed is a good way to improve your SEO ranking and provide a better user experience for your visitors.

Here are some best practices for types of pages not to index:

Duplicate content pages. If you have multiple pages with the same or similar content, it's generally a good idea to avoid indexing all of them. This could include printer-friendly versions, alternate language versions, or slight variations of the same content.

Thin or low-quality content pages. Pages with little or no content, or pages with content that is poorly written or irrelevant to your target audience, should not be indexed.

Internal search results pages. These pages are typically not meant for users to land on directly, and they can clutter up search engine results pages (SERPs).

Privacy and policy pages. These pages are typically not relevant to search users, and they can contain sensitive information that should not be indexed.

Thank-you pages. These pages are typically displayed after a user submits a form or makes a purchase, and they are not meant for indexing.

Login and checkout pages. These pages are typically not relevant to search users, and they can contain sensitive information that should not be indexed.

Staging or test pages. These pages are not meant to be seen by the public, and they can clutter up SERPs.

Paginated pages. If your paginated pages contain the same content as your main product or category pages, you may want to consider noindexing them. This will help to avoid duplicate content issues.

You can use a number of methods to prevent pages from being indexed, including:

Robots.txt file. You can use your robots.txt file to block search engines from crawling certain pages on your website.

Noindex meta tag. You can add a noindex meta tag to the header of a page to prevent it from being indexed.

Canonical tags. You can use canonical tags to specify which version of a page is the preferred version for search engines. This can be helpful for preventing duplicate content issues.

It's important to note that noindexing pages is not always necessary. For example, if you have a blog with a lot of high-quality content, you may want to index all of your pages, even if they have similar content. However, if you have a lot of low-quality or irrelevant pages on your website, it's a good idea to noindex them to avoid harming your SEO.
