First, you need to go to Google and type in the following
search queries:

"Daily Link Roundup"
"Weekly Link Roundup"
"Monday Link Roundup"
"Friday Link Roundup"
"Link Roundup"

If you want to find blogs that are specifically related to your
market, then you can add a modifier. Something like:

"Weekly Link Roundup" + parenting
"Weekly Link Roundup" + marketing
"Weekly Link Roundup" + moms

Simply attach your main keyword to the search query.

This will give you a list of blogs that do weekly link roundups.
Link roundups are basically where bloggers post their favorite links
and articles each week in what’s called a Link Roundup.

Best of all, there are thousands of blogs that do this on every
imaginable topic. Now here’s where you come in…

Once you’ve found a related blog that does link roundups you can then
contact the blog owner and send them a link to your very best
content from your own blog. If you’ve published truly great content, then there’s a very
good chance that they will link to you in their weekly link
roundup.

This gives you a high-quality backlink and sends you some laser
targeted traffic.
