Dynamic Parameter Actions are applied throughout our system—our crawler and ranking algorithms. All systems rewrite any instance of URLs from your site as per the applied action. This has numerous benefits:

Crawl Benefits

1. More efficient crawl of your site, we will be crawling fewer duplicate URLs. The crawler should stop crawling older version of the URLs within a few days.
2. Better and deeper site coverage as we will be able to use our crawler to find more new content on your site and index more unique content from your site. his occurs over time as crawl and index capacity is freed up from duplicate URLs.
3. More unique content discovered also due to the ability to handle more dynamic parameters in your URLs, due to the removal of content-neutral dynamic parameters. The dynamic parameters in URLs are better used within a few days as the URLs are rewritten resulting in more content discovery over time.
4. Fewer chances of crawler traps. This occurs within a few days.

Ranking and Display Benefits

1. Better site ranking due to reduced fragmentation of links and anchor text to your site's pages. The rules apply in the crawler within a few days and then we recrawl your old URLs with the new rules as they get scheduled. There is some ranking benefit soon after the URLs are recrawled. However, for a site with a lot of referrals, the benefit can continue to accrue for a few months as all URLs linking to your pages are recrawled and their links reprocessed.
2. Your URLs in search results will also get shorter and easier to read for users.
