There are several types of seed keywords you can use : broad or narrow ones.

A broad seed keyword like car will generate some general keyword ideas and can help you better understand the topics related to your business.
These keyword ideas are usually more competitive.

A narrow one like best car for will provide more targeted, long tail, keyword ideas that might be more interesting as you'll get a majority of high-intent keywords.
These keywords ideas are usually less competitive.

When using a wildcard (*), in the seed keyword, keyword ideas will match a specific structure.
For example, best car for * will only provide keywords that are of type "best car for something".
how to * car => "how to something car".

I recommend playing around with the more specific and wildcard searches to generate some highly relevant keyword ideas.

Example of keyword ideas per type of search :
car : 2913 (broad search)
best car for : 1374 (more specific search)
best car for * : 339 keyword ideas (highly targeted search)

Yes. Just head to the import section.

1. Give a name to your report.

2. Add your website URL or the max DA.

3. Add your keywords (1 per line)

4. Choose a location.

5. Let the tool analyze the SERPs of all provided keywords.

1 keyword / SERP analyzed = 1 credit

Articles built on a main keyword with an estimated volume below 10 can bring you much more than that !
However, It's difficult to know how much more. It might be 2 times as it can be 10 or 20 times more.

The below traffic graph shows traffic on an article with a main keyword that has an estimated traffic < 10.

The main question you should ask yourself is : does it make sense to write on it ?

Also, writing content on these will help you build topical authority and push ranking on other, higher volume, more competitive keywords.

In conclusion : low volume keywords can be a real opportunity for your website.

Always analyze the weak spots from the top 10 search results first. 
Can you do better ? Provide more insights ? better graphics ? answer more questions ? provide a more personal touch ?
Consider all aspects that could bring value to a reader.
If you write something better, you'll have a high chance of replacing one of the current weak spots.

Go to the settings tab > Negative Keywords and add any words you don't want to see in your report. 
This will hide keywords containing any of the negative keywords. 

Examples of negative keywords often used : Amazon, Best Buy, Walmart, UK, Australia, ...

Keyword ideas are fetched straight from the Google Auto Suggest API + some other Google sources (secret 😉). 
Several modifiers are used around your seed keyword to try and extract as many keyword ideas as possible, with a focus on high-intent keywords.
Example of modifiers : "How to", "Best", "Top", "Review", "vs", "Why", "When", "What", ...

All keyword ideas found are queries that users type in Google (ie there are real people searching for them).

The aim of the tool is to replace the manual work of going through the SERPs.

What you do with a classical keyword tool like ahrefs is :

Analyzing the SERPs for a large amount of keywords could take several hours or even days.
With LowFruits, you get your analysis done in a matter of minutes.

If you don't have a website or are just starting out, don't add a max DA value. 
By default, it's at 20 (ie weak authority).

If you already have a website, add it in the corresponding field. When analyzing the SERPs, LowFruits will then look for websites weaker than yours and tag the corresponding keywords as low fruits.

There are several metrics out there to assess the authority of a website. DA (Domain Authority) is one of them.

It's a metric created by MOZ, that is basically a proxy to the number and quality of backlinks to a website. 

When you're just starting out, on a brand new domain, you basically have no backlinks and therefore no authority yet (the DA is at 0). 
At this early stage, you can't compete with big websites that have a ton of authority - you'll compete with other websites that are at similar stage or already have a few backlinks.

Knowing the DA of your website is therefore an important metric for your content strategy.

When you're just starting out, aim to compete against websites that have a DA below 20.

If you have an affiliate website, you're mainly competing with other affiliate websites.

Google understands that a website is an affiliate, a shop, a media or some other type and some keywords are more relevant for certain type of websites.

Use the advanced view and/or competition tab to find the affiliate websites you are really competing with !

Did you know that some affiliate websites try to fake their type ? 
By installing WooCommerce and placing a shopping cart in the navigation bar, they try to be seen as an e-shop by Google to rank on more commercial intent keywords. 

The corresponding weak spot might just be lucky, use PBNs or Google might have just pushed it at the top for a day.

In general, the fewer the number of fruits, the more difficult it will be to rank in the top 10 search results.
Always analyze the specific website or forum page to see if you can do a better job.

Content on higher volume keywords will generally take more time to rank in search engines.

You'll need to analyze deeply what the weak spots are doing well that you could do even better.
Also, you would probably need to need to build topical authority by linking together articles written on several related keywords.

In other words, the on-site and off-site job requires more work than lower volume keywords.

When starting out, I recommend not to start with these higher volume keywords. 
You would be better handling first the long-tail, low volume ones.

Basically the more fruit icons, the easier it is. 

But you would need to check each low fruit page to see how easy or hard it would be to do a better on-site job. 

By hovering on the icons, you get the URL, the Domain Authority (DA) and the type of website (affiliate, blog, e-shop, media, social, ...). Click on them to access the related webpage.

Higher volume keywords (> 1000) would also take longer to rank on, even if they have many fruits.

Credit consumption can go fast on some broad topics.
Also, some niches are more competitive than others, so you’ll find fewer keywords to target.

The trick to minimize credit consumption and find more relevant low fuit keywords is to start with more specific seed keywords.

You can generates a dozen of reports based on specific seed keywords (for free !).

So instead of the broad “air fryer”, use a seed keyword that already has an intent (with and without wildcards) :

how to * air fryer
how much does air fryer

For each report, select the free option, export all the keywords into an Excel, merge the data and imports it back into LowFruits for analysis of the SERPs (can now be done using the Lists feature).

The result ? ​
You get a report with content for months on highly-relevant, easy keywords.
At the end, you saved a lot of time on SERP analysis at a low cost.

SERP analysis starts at $0.005 / SERP analyzed.
By analyzing 200 SERPs, it will only cost you $1. 

Analyzing such an amount of keywords, one by one, directly in the SERPs would have taken you several hours or even days. 

It really depends on the seed keyword and the competitiveness of the topic.

A typical wildcard (*) search would generate around 100 - 300 keyword ideas.
Analyzing all the SERPs would cost between $0.5 and $1.5 (on the high 50 000 credits plan).
From these, around 5% to 90% (5 to 270) could be low fruit keywords (quite a range indeed :p).

A very broader search (like 'fat loss' or 'car') could generate up to 2000 - 3000 keyword ideas.
Analyzing all the SERPs would cost between $10 and $15 (on the high 50 000 credits plan).

What I recommend is going for narrower seed keywords unless you want to get a global view on the competition of a niche.
