Hi guys,

I'm currenty creating a site right now, and I'm just a little concerned about my ASP pages. How do search engines crawl these pages? Do search engines treat these pages differently compared to html pages?

A few focused, practical points to add to the thread that build on what , and touched on and answer ’s question more precisely.

Start with a short audit checklist you can run now:

  • Ensure each piece of content has one preferred URL and indicate it with a rel="canonical" tag (helps when filters or tracking parameters create many variants). See Google’s guidance on consolidating duplicate URLs (Consolidate duplicate URLs).
  • Produce a clean XML sitemap that lists the canonical URLs and submit it to Search Console (Sitemaps overview).
  • Avoid exposing session IDs or unbounded filter permutations in URLs. If you must use query parameters, keep them predictable and canonicalize the output.
  • Verify crawlability with Search Console’s Coverage and URL Inspection, and by sampling server logs to see how bots traverse your pages.

ASP.NET-specific notes:

  • URL rewriting/routing (IIS URL Rewrite or ASP.NET routing) can make links friendlier, but the rewrite itself is just an implementation detail — what matters to search engines is a single consistent URL for each resource, correct HTTP status codes, and usable links.
  • If content is rendered only via client-side JavaScript, provide server-rendered HTML or use progressive enhancement so crawlers and link-following bots can discover your content.

Troubleshooting quick wins:

  • Confirm important pages return 200 and aren’t accidentally blocked by robots or a noindex.
  • Use the URL Inspection tool and your server logs to find duplicate crawled URLs and remove or consolidate them.
  • When changing a URL permanently, use a 301 and update internal links; for temporary changes, use a 302.

Server generated pages get crawled the same as static ones. Word of caution however, server generated pages are usually quite sloppy and can interfere with a full crawl. Things to avoid are:more than one Title, embeded tags, duplicate tags like <head> and <body>, duplicated descriptions, excesses of general coding errors.

Hi Fred,

I read somewhere that characters in the URL's of dynamic pages such as question marks and ampersands can disrupt the search engines crawlers. What is your input on that?

In my own experiences, search engines have no difficulty in dealing with dynamic issues as you might have seen many top 10 sites for hot keywords are dynamic. Of course, you could use some SEO add-on for your ASP site and turn your urls into static ones for more customer friendly purpose. :)

Have a nice day,

I think, static urls are more search friendly than dynamic urls..so you can convert it from dynamic to static using 301 redirect..
