block google web crawler with robots.txt and a regex pattern inside to stop crawling for publications in MLA format on my webpage
 To block Google web crawler (Googlebot) from crawling publications in MLA format on your webpage, you can use the `robots.txt` file and a regular expression pattern. Here's how to do it:

1. Create a `robots.txt` file in the root directory of your website if you don't have one already.
2. Add the following lines to the file:

```
User-agent: Googlebot
Disallow: / \.html$|/\.html\/.*[Mm][Ll][Aa].*
```

This `robots.txt` file will disallow Googlebot from crawling any URL ending with `.html` or having a path containing `.html/.*[Mm][Ll][Aa].*`. This regular expression pattern should match URLs containing MLA format publications.

Please note that while most well-behaved crawlers will respect the `robots.txt` file, there is no guarantee that all crawlers will follow these rules. Also, this will not prevent the content from being indexed if it has already been crawled or if other sites link to it. To ensure that your content is not indexed, you should use the `noindex` meta tag in the HTML head of the pages you want to exclude.
block google web crawler with robots.txt and a regex pattern inside to stop crawling for publications in MLA format on my webpage

To block Google's web crawler (Googlebot) from crawling specific MLA-formatted publications on your webpage using a regex pattern in the `robots.txt` file, follow these steps:

1. Identify the pattern that is common among the MLA-formatted publications you want to block.

For example, let's assume that the MLA-formatted publications start with the string "Works Cited" and are followed by a line break. In regex, this pattern can be represented as:

```
Works Cited\s*\n
```

2. Open or create a `robots.txt` file in the root directory of your website if it doesn't exist.

3. Add the following lines to the `robots.txt` file, replacing the regex pattern with the one you identified in step 1:

```
User-agent: Googlebot
Disallow: /*\s*Works Cited\s*\n
```

This code tells Googlebot to disallow crawling any URL that matches the provided regex pattern.

4. Save the `robots.txt` file and upload it to the root directory of your website.

Now, Googlebot should respect the `robots.txt` file and stop crawling the MLA-formatted publications that match the provided regex pattern
