In terms of getting your website crawled and indexed by Google, it is vital to understand URL parameters. Failure in the management of these parameters leads to such problems as duplicated content, crawling problem, and even, the indexing issue. Here are the URL parameters which you should be aware of and how to best deal with them;

1. Session IDs

Sometimes the IDS is added to the URL to identify the user’s session. Although very helpful for session management, they can easily generate several URLs to the same content which is bad in terms of SEO. To prevent this, it is recommended to replace session IDs in URLs with cookies or configure the look and feel of Google Search Console to show that these parameters do affect the content.

2. Tracking Parameters

Parameters, including the UTM codes, are normally applied in marketing campaigns to monitor links’ effectiveness. However, these parameters bring out the creation of numerous similar URLs, which would have deleterious effects on crawling. Google usually indexes these as the same URL, however, it is advisable to canonicalize URLs or set parameter handling in the Google Search Console.

3. Pagination Parameters

Many Web developers use URL parameters such as page=2 for implementing the pagination. For proper crawl control on paginated pages, the rel=” next” and rel=” prev” tags should be used properly. They serve to indicate the context of linked pages and the order of their sequences, thus increasing the speed and convenience of crawling for users and the company.

4. Sort and Filter Parameters

To reverse or sort the items listed on the e-commerce site, one is likely to notice hyperlinks in this format: sort=price_asc or filter=red. These can generate a lot of URL versions of the same content. To avoid having Google crawl these variations and wasting the crawl budget, it is advisable to use robots. txt file to exclude such parameters or use the URL Parameters report in Google Search Console to indicate how those parameters are to be managed.

5. Language and Location Parameters 

Sites that are in different regions or languages may use parameters such as; lang=en or region=US. Make sure that Google recognizes such differences properly using hreflang tags that define which language and regional release of the site should be displayed for the same query to users of different Google services or in different geographic locations. 

In summary of the topic of the paper, the ‘ Best Practices of URL Parameters’ are as follows: 

• Canonicalization: Employ the use of canonical tags to inform search engines which of the URLs is original. This helps to prevent the indexing of two or more URLs that are similar because, in the process, the search engine merges them into one version.
• Google Search Console: Head over to the URL Parameters tool in Google Search Console to help Google determine the nature of specific parameters. For instance, you can instruct Google not to consider some parameters that are irrelevant to the website’s content. 
• XML Sitemaps: Update and resubmit the XML sitemap to Google regularly. This makes sure to get all vital URLs indexed and make the Google bot alert to any new entries or changes. 
• Avoid Unnecessary Parameters: This makes your URLs simpler and more manageable; besides, it makes it easier for Google to index your site. 

URL parameters are one of the elements that help Google crawl and index your website; better control over URL parameters can provide substantial jumps in the promotion of your site in search results.
