I tried to google it, and found out that you can not submit your site to ask, here is a quote explaining why.
It is not possible to submit a website to Ask.com. Although Ask.com is a
search engine, it is a search engine with a difference. It is a
questions and answers based search engine.
And here is a quote from a site telling about the next best thing you then can do to get your site found by Ask:
Ask does not have an URL submit feature. Until recently, you could
submit your sitemap to them. But Ask.com has now retired this feature
and says they will be crawling sites instead. So, the next best thing is
to add a directive in your robots.txt file that specifies
auto-discovery of the XML sitemap.
Like this:
SITEMAP: http://www.the URL of your sitemap here.xml
The sitemap location should be the full sitemap URL.
Your sitemap should be placed on your site like this http://example.com/sitemap.xml
So it seems like having a good sitemap would be the preferred way to get found by Ask
This is how you put the directive in the robots.txt:
To facilitate auto-discovery of your sitemap file through your
robots.txt, all you have to do is place a directive with the URL in your
robots.txt, as shown in the sample below:
Sitemap: http://www.example.com/sitemap.xml
So, the robots.txt file looks like this:
Sitemap: http://www.example.com/sitemap.xml
User-agent:*
Disallow:
NOTE: The directive containing the sitemap location
can be placed anywhere in the robots.txt file. It is independent of the
user-agent line, so it does not matter where it is placed.
Hope this help you.
