The filters that we added to the Related Keywords tool help you narrow down your results to the ranges that fit your needs. Here's a look at the filtering options you have and why you might use them.

In our Related Keywords overview, we showed how you get different results for the keyword “eye fatigue” when you choose the “Also Ranks for” option.

Other domains that rank for this keyword also rank for:

  • Astigmatism
  • Glaucoma
  • Pink eye
  • Eye twitching

These are high-volume short tail keywords, so you probably think of these two things:

  1. This must come from nearly untouchable domain like
  2. These short tail keywords will be tough to rank for

The first idea is likely, but the results will come from a blend of top-ranking domains. The second thought is valid, and very likely. That’s where our built-in filters come in. You can account for any “yeah, but” ideas that you get when you first see the results.

Yeah, but these are all tough to rank for.
Filter by keyword difficulty but set a minimum to make it worth your time.

Yeah, but these are short tail. I need long tail keywords.
Filter by word count. 

Yeah, but some of these focus too much on glasses.
Filter out words using the exclude feature.

You get the idea.

Include/Exclude functionality 

This is an easy way to fine tune your results. Knock out topics that don’t belong, or zero in on a more precise niche that you’d like to see.


This is the estimated number of times this past month that people have searched this keyword. The numbers reflect searches done in the US on (or in the UK on if you are looking at UK data).

Keyword Difficulty

We’ve calculated how difficult it would be to rank on this keyword. The score is based on a scale of 0-100 (with 100 being the most difficult to rank for). 

Our keyword difficulty score takes into account the strength of the domains, on-page signals like “keyword in title,” and the number of .gov and .edu domains. You can set the range or leave it open-ended, setting a minimum or maximum point.

Word Count

This literal count of individual words in the search term is a way of finding longtail keywords. The more words you have, the more likely you are to get longtail terms.

Adult Filter
Some keywords can trigger variations with NSFW terms. Since it's not always expected, we include a default filter that hides these terms until/unless you uncheck the box to show them. 

When there are sensitive terms in the results, the "Adult Filter" will become active, and you can see how many words we've hidden. Once you uncheck it (or x out the filter), those keywords get added back into the total results, and we update the roll-up metrics at the top of the page.
