Show HN: I built a service to discover rapidly growing Google search topics

Hey everyone, Josh here the creator. As a developer, I’m always looking out for an emerging market trend on which to bootstrap my own SaaS product. This is since market awareness and timing are often so critical, on top of execution skill of course!<p>So I built Trennd. Under the hood it continually monitors the web for interesting keywords &amp; topics, classifies them using Google Trends data and packages everything as a neat web app where other people can contribute too.<p>The app itself is built with the Next.js React framework along with Express, Bootstrap and MongoDB. Next.js was new to me, but made sense since it comes with so much out of the box, including server side rendering.<p>Let me know if you have any questions, and any feedback is much appreciated!

This definately has a market, but i&#x27;m not sure SaaS is it. More typical eCommerce products have a &quot;flavor of the day&quot; like effect, where an article is written in some niche community, and everyone in that community rushes out to buy the thing. Then a few months later, the craze is over. If you&#x27;re Amazon, you can spot these trends easily (because they have everyone&#x27;s sales data from the marketplace). If you&#x27;re a small eCommerce company, unless you just happen to have that product on hand, and someone just happened to have found you, you may never even realize the trend existed. Being alerted that there is a sudden demand for a product, might give you a headstart on marketing and might help you negotiate a deal with a supplier before the supplier realizes what they have.

Very cool! As a front-end dev it&#x27;s interesting (but I guess also not surprising) to see React and Vue with very steep curves.<p>I wanted to try adding Svelte, so I signed up by email, but that doesn&#x27;t seem to be working. Then I tried Sign In With Twitter but, wow, it requires an awful lot of permissions! Among them... Follow new people, Update your profile, and Post Tweets for you. I&#x27;d be a lot happier signing in with Twitter if it were limited to read-only abilities.

This is similar in some ways to <a href="https:&#x2F;&#x2F;meetglimpse.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;meetglimpse.com&#x2F;</a><p>The key value-add, in my mind, from that product, besides the trend, is the editorial content they include in the email. Of course, that&#x27;s just me as a layperson.<p>I&#x27;d probably dupe their pricing model and approach: i.e., a limited number of weekly&#x2F;monthly trends, subscribers get more.

Is there a plan to sell the data as an API?<p>I am currently working with a client who is exploring the options for building out a similar system.

How can there be a big spike in the &#x27;cattle&#x27; trend - <a href="https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;cattle" rel="nofollow">https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;cattle</a> - but no corresponding change on Google Trends - <a href="https:&#x2F;&#x2F;trends.google.com&#x2F;trends&#x2F;explore?date=today%205-y&amp;q=undefined" rel="nofollow">https:&#x2F;&#x2F;trends.google.com&#x2F;trends&#x2F;explore?date=today%205-y&amp;q=...</a> ?

Is there a Pro version where I can get alerts and manage my keywords etc and have a dashboard?
crypticaalmost 6 years ago
It&#x27;s interesting to see that topics like &#x27;fentanyl&#x27;, &#x27;opiod&#x27; have done up.<p>Also &#x27;criminal defenses&#x27;, &#x27;wrongful death claim&#x27; have gone up a lot as well - Perhaps they are related to spikes in searches for plastic surgery topics.<p>Also it&#x27;s weird why almost all the topics on the front page are related to software development. It&#x27;s like there is some kind of conspiracy to turn the world&#x27;s population into software developers.
tdubernealmost 6 years ago
Nice idea. For very short time spans, I noticed some &quot;trends&quot; seem to be seasonal trends (&quot;aperol&quot;, &quot;lawn mower&quot;...). It might be interesting to compare with the trend for the same search the year before at the same period, to be able to identify those cases (for intance, I cannot see from the graphs whether Aperol is more or less trendy this summer compared to last summer)
driverdanalmost 6 years ago
Where&#x27;s the data coming from? I assume the trends are coming from Google Trends but how are topics found?
tw1010almost 6 years ago
The examples on the front page looks surprisingly good, which makes me suspect they were hand-picked. Kind of beats the purpose of the app if I&#x27;m just shown trends the author and me already know about, since we seem to inhabit the same subcultures.

What about also crawling data from AdSense? That way you also get the search numbers, not just the relative graph.<p>You see these numbers as part of planning for a campaign. There is also an API for it.

Many years ago I built a service on appengine to hit the auto complete api endpoint for every single and 2 letter prefix, as well as things like &quot;how do I&quot; or &quot;what is the&quot;.<p>It ran for a few months before blowing up the free quota, but it was pretty cool while it lasted.. Seeing certain things bubble up and then disappear. Like right now &#x27;lion king&#x27; is the first suggestion for &#x27;l&#x27;, but I doubt it was a month ago.

So... whats up with: <a href="https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;craft-beer" rel="nofollow">https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;craft-beer</a><p>A peak every April and a dip every December? This seems like the result of some smoothing algorithm needing ~4 months of data and resetting every year.<p>This one even more consistent: <a href="https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;airbnb" rel="nofollow">https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;airbnb</a>

I wonder if it would not be more interesting to see the unique search queries instead ie. the least popular search queries.<p>(In the spirit of &quot;YouTube videos that have almost zero previous views&quot; [1] &#x2F; astronaut.io)<p>[1] <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20432772" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=20432772</a>

I&#x27;d also like to see downward trends, not just growing trend. From the last page or two, I see some downward trend, like &quot;blog&quot;, &quot;facebook&quot;, and &quot;gmail&quot;. I don&#x27;t know if it means the decline of popularity, but it is definitely interesting to see the declining graph.
anarchitectalmost 6 years ago
Brilliant stuff. Fascinating to see how seasonal some of the searches are – &quot;rosé&quot; and &quot;Aperol&quot; spikes in July and December (southern&#x2F;northern hemisphere summers?), &quot;carbs&quot; and &quot;low-carbohydrate diet&quot; peaks in January (when people want to change their habits?).
abbadaddaalmost 6 years ago
This is pretty brilliant. I&#x27;d hook up something to identify trends with companies that can potentially be invested in. Could be useful from a publicly traded stand point (Good ole stock picking) or even VC investing if the product was rapidly growing and not yet heavily invested in.

Very minor bug - if a user has an emoji in their Twitter name the default blank avatar doesn&#x27;t quite work correctly - <a href="https:&#x2F;&#x2F;trennd.co&#x2F;user&#x2F;5d31d11ce6f3ce02e53269c7" rel="nofollow">https:&#x2F;&#x2F;trennd.co&#x2F;user&#x2F;5d31d11ce6f3ce02e53269c7</a>

Is there some open source version of something like this? I would be interested in monitoring some non-tech topics and it would be useful to have something with most of the basic features in place to do so, even if it&#x27;s a library
libriaalmost 6 years ago
`Gmail` appears to be trending down but exhibits local maxima right around Spring and Fall equinox: <a href="https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;gmail" rel="nofollow">https:&#x2F;&#x2F;trennd.co&#x2F;trend&#x2F;gmail</a><p>Now why would that be...

As a quick feedback, currently the front page has no indication what use signing up is.

This is awesome. I&#x27;d love to have the ability to view topics based on category. IE. see the biggest trends in entertainment or the biggest trends in sports players, or the biggest trends in startup brands.

Very cool, but this is essentially not &quot;discovery&quot;. There is a heavy skew toward tech - but niche tech (Notion for example) specifically. It would be cool to get a broader, less bias perspective.
terrycodyalmost 6 years ago
If possible, I&#x27;d like ti integrate with the real monthly search numbers for each keyword, I can&#x27;t get it anywhere, only see a trend score, could u explain a bit more on this?
donmatitoalmost 6 years ago
That&#x27;s very neat and interesting; I guess the two questions are - how do you generate keywords to search for ? - how do you filter out noise (or perhaps you don&#x27;t filter it) ?

This could have massive potential with music industry A&amp;R&#x27;s looking to capitalize on viral songs. That&#x27;s where virtually all recording contract money is going nowadays.

Looks good, but I miss units on the axis. On mobile, it&#x27;s missing from the start page. The units for the y-axis on the detail view is missing (as far as I can see).

What is your Algo for calculating Trends? I mean how do you say that something is trending? It is most popular? Emerging? Z-score?

Are topics coming from twitter trending? Also, can you add filter of industry-wise topics? Good work btw :)
