Sorting and Choosing Keywords for App Store

Updated: 12 Mar 2019.

Suppose you already have plenty keyword ideas for your app. Or, at least, you understand how to select them.

There are so many promising keywords, but in App Store their total length is limited to 100 bytes including commas. This post describes a sensible way to select a few keywords which will give the best search performance.

Organize Keywords in a Spreadsheet

Additionally, suppose that the target app is named Plant Classifier and it's a visual recognition deep machine learning neural network startup based app, allowing users to identify a plant by it's photo. Here's its icon:
(it's the kenaf and not what you think)

Your keyword ideas are: taxonomy, systematics, species, genus, name, identifier, identify, determine, search, herbarium, botany, nomenclature, photo, picture, image, atlas, visual, recognition, analysis, flower, tree, shrub, weed, herb, garden, leaf. Their total length without whitespaces will be 200. It's actually a good practice to have at least twice as more words than you need, before you started to cull them.

You think the app page with such keywords will easily match searches like:
  • plant species
  • identify tree genus
  • or determine flower by picture

Now do the first simple yet important step: create a spreadsheet. Make a column named Keywords and paste all 26 ideas there.
The spreadsheet will allow you to store keywords data in the convenient way and finally sort it. I prefer Google Sheets but any other tool will meet our demands.

Analyse App Store Search Results

The next thing you do is literally "go to App Store and search apps using each of the keyword candidates". Sure, this is the most precise way to evaluate the concurrency. The most competitive words will evoke more search results. Luckily we don't need to do this manually, because we have Keywording utility based on iTunes Search API.

For example, the request:
./keywording "taxonomy,species" NZ will give: NZ species 164 taxonomy 26
Create a column: Concurrency, App Store results. Set the country to more popular US store and perform search for all the words, filling the newly created column:

Estimate Search Volume

To estimate the search volume we will use Google Ads Keyword Planner. It can tell, how many searches users perform in "Google and search partners" network, and again, it's not the data we desire, but we assume, that Google searches will be quite close to the App Store ones. After you open the Planner, follow this steps:
  1. Select "Get search volume and forecasts" box.
  2. Paste keywords there, and click GET STARTED.
  3. You will see the results under FORECAST section.
The current version of Keyword Planner provides Clicks and Impressions - both metrics are characterising the volume. But I recommend to use Impressions because it's more stable. In our case words photo, picture and image have enormously heightened clicks.

Other recommendations: don't specify any particular location to enlarge input data (if your app isn't country-bound), but specify the language. Best time range is "next month".

Now set English language and write Impressions to the spreadsheet under Impressions, Google column. You will get something like this:

Determine Linguistic Frequency

Linguistic frequency is especially helpful with languages you are not very good at. If you found a couple of synonyms for a keyword, it can help you to find which one is more common to native speakers. Also, the frequency may help you to make a decision when the other indicators are equal. Generally, this step is optional and can be skipped.

But in the educational purpose you will determine the linguistic frequency of each keyword using Ngram (so many great tools by Google!). Paste first 12 comma-separated words in the search field, check "case-insensitive", select the 3 last years (currently the freshest data are from 2008, so select 2005-2008 range) and hit the Enter. Now you can take a screenshot of the values:
and after spending some time while putting them into the Ngram, frequency column of the table, you will get:

Sorting and Choosing

Time for the final part for which we were preparing since the beginning of the article. Analyse your data. First, look at the Concurrency column. Most of the keywords have values < 200 and that means that the competition is sufficiently low. You likely to choose some of them. Now select all the data and sort it by Impressions, decreasing. Have a look at it:
Noticed the words with low concurrency but high search volume? They are "golden", you choose them, definitely. First five are highlighted with yellow: garden, tree, leaf, name, herb. Their total length is only 26. You need sufficiently more.

If we select all words with low competition, we will obtain the following: garden, tree, leaf, name, herb, analysis, shrub, recognition, herbarium, botany, visual, taxonomy, genus, species, identify, nomenclature, determine, systematics (total length - 144). Some words have to be dropped.

Now sort the table by Concurrency, increasing. What do you see there?
Some quite unpopular, low-concurrent yet meaningful in the context of your app words, like: herbarium, taxonomy, botany, shrub, they are silver words (blue). If you need to drop some words, you better leave them.

Another interesting group is so-called red words which are popular, highly concurrent but closely describe your app. Such as flower, image, picture, photo. Consider them if you need to add some words to the final selection.

So, suppose, you drop analysis, nomenclature, systematics, determine (not very suitable, anyway). Now we you have exactly 100 characters: garden, tree, leaf, name, herb, shrub, recognition, herbarium, botany, visual, taxonomy, genus, species, identify. So neat!

Other Considerations

But could it be neater? There is still a place for the art in the keyword optimisation.

Plurals can be replaced with singulars. The search algorithm will treat them the same. This also true for verb vs. noun forms and for typos. So, you can replace recognition with recognize saving 2 characters. This information isn't robust, in practice it works for English keywords, but keep in mind that Apple may change their algorithms any time.

Choose not only keywords, but their combinations. For example garden keyword is very sweet according to our research. But, how folks supposed to use it? Make some lame request like app for garden? You shouldn't rely on that. Instead, take at least one of "red" image-related words, let's say ... image.

BTW, you probably already noticed that weed is somehow super-popular in the App Store, but has 0 impressions according to Google. It's the worst possible indicator. How could it be? If we open App Store and search for this keyword, we will see that store is literally spammed with trashy apps, which are unrelated to our topic. You better avoid such keywords if you want your app to be age rated 4+.

In conclusion, we've got 14 most efficient keywords of total length 97 characters without whitespaces: image, tree, leaf, name, herb, shrub, recognize, herbarium, botany, visual, taxonomy, genus, species, identify. And most important, you learned predictable (almost scientific!) way to gauge keywords, to finally make a sensible selection which will elevate your app to the top of the targeted search results.

The example spreadsheet is available in HTML and Google Sheets.

Support Story: "Pls, Make a Tutorial"

As an individual developer, I convinced to fulfil support job for my customers. Each app in App Store should have a support link. For this purpose I use Google Forms (free hosting, pretty convenient). Periodic Timer also has a Facebook group. And that's amazing, that people really tend to write questions and suggestions to me! Though there always a percent of offtopic. I think the regular sharing of funny conversations is something that may happen on this blog.

And today's hero (call him Wob for anonymity) was someone, who pretty obstinately wanted me tutorial to the Periodic Timer (which is totally simple and intuitive app, BTW). He wrote directly to my support email and we had this funny conversation:

I just downloaded Periodic Timer but can find no instructions on how to use and fine-tune it.
Can I set the sound it makes or the volume, for example?
Do you have a set of instructions you can email me?
Thanks.

Periodic Timer is simple and intuitive app that doesn't provide complicated options and can be can be understood without any instructions.
Change volume of Periodic Timer like you change like you do it with Alarm or Ringtone.
Good Luck :)

If it were as simple and intuitive as you claim, I wouldn’t have asked you for basic instructions. Please explain. (I can’t be the only person who’s asked for this information.)

You are :)
How about the first link from the google? https://www.wikihow.com/Adjust-the-Volume-on-iOS-10
Have a nice day.

I think you misunderstand. I didn’t want just info about volume.
How do I use your app: 1, 2, 3? It’s too minimalist for me.

Thanks.


And then the story continues, tutorial-guy creates a new email for disguise, something like w.wob@gmail.com, and continues to solicit me for tutorial. I answered quite roughly:

Just look at yourself:

I can’t figure out how to successfully use your app. It’s very frustrating. Can you make a better tutorial? Also, I’ve already upgraded but i keep getting reminders to upgrade again. Please fix these bugs

You are creating multiple emails and spam me with "ples make a tutorial" messages. Why do you even do this? I suppose you are one of retired mans who has plenty of free time but no one to talk to.

I want to tell you one simple thing: this app is my hobby so, please, don't wait I will run around you trying to satisfy any of your whims. I have no free time, and also this app doesn't brings any money at all.

So, I hope you quite clever to understand me, if not - don't be surprised why I ignore you.


Still not sure, was that an attempt to flirt with me?
