Some years ago, McDonald’s sold the BigMac “Secret Sauce” in bottles for the first time, including a detailed list of its ingredients. Before this, the sauce ingredients and recipe were kept a secret. The sauce is said to be delivered to franchises in sealed containers. Employees in the know about the sauce ingredients are even said to have signed non-disclosure agreements to keep them from revealing the secret ingredient list.

Here at Spotler, it doesn’t take an NDA to keep the sharp minds that are behind our search technology from talking. They prefer developing new features and functionalities… rather than talking about them.

But we’ve been able to hunt down our lead developer, who has revealed some of the main ingredients that make up the Spotler Activate Search Secret Sauce. Curious? Take a look:

And there you have it, the main ingredients of the Spotler Activate Search Secret Sauce recipe.

You’re saying this isn’t 100% clear to you? Don’t worry, we have you covered! Let’s take a close look at the ingredients, at how the Spotler Activate Search search engine works. How does it ensure your searchers always find what they’re looking for on your website within milliseconds? And that the most relevant results appear at the top of the results list?

The main ingredient: Spotler Activate Search Standard Rank

Spotler Activate Search’s standard relevance is based on several different ingredients. The total of these ingredients forms the Spotler Activate Search Standard Rank. This is a score that is purely based on the content within your document, in particular:

  • Number of terms in the document
  • The frequency of terms in the document
  • The infrequency of terms in other documents
  • Query field boosts
  • Length of the document

The Spotler Activate Search Standard Rank can be a number running from 0 to X, and it’s influenced by your content, settings, and optimizations. Content is the most important influence factor to relevance. If a document is not relevant to the query, it might not end up near the top of the results list, despite it having been boosted.

Optimisation Ingredients

Within your conversion cockpit you can assign boost factors to your search fields. With these factors you’re letting the system know which fields have relatively higher importance than other fields. Let’s look at an example. We’re seeing 3 documents below for which you have the title boosted with a factor of 1.0 and the description field with a factor of 0.5. You’re telling Spotler Activate Search that your title fields are more important than your description fields when it comes to matching your documents to the search query.

If your user now types in the query “shoes”, he/she will get the following results:

  1. Document 2 (1.0 + 0.5 = 1.5)
  2. Document 1 (1.0)
  3. Document 3 (0.5)

With Ranking Rules, you can add additional scores to the Spotler Activate Search Standard Rank of documents, letting the search engine know which products you really want to see on top of the result lists (e.g. because they are your housebrand or your high-margin products).

It’s important to stress though that these are only additional scores, meaning that your document content is still king. If a document’s content is not relevant to a query, a Ranking Rule will not overwrite that, and the other way around: if one of your documents is very relevant to a query, it still shows up in the results, even though you have demoted it with a Ranking Rule. It will simply show further down in the results list. 

Spotler Activate Search’s search result re-ranker powered by machine learning works very similar to a Ranking Rule: It adds scores to the Spotler Activate Search Standard Rank based on number of clicks. The algorithm learns which products are clicked on most for each query and adds respective scores. As you can see, relevance is still king when you have clickrank enabled (as scores are simply added).

However, we’re taking things to the next level here, as besides turning on clickrank, you don’t have to do anything, and you’re even able to cater to seasonalities. Let’s take a look again at an example: Different kinds of leather jackets could have the same document relevance for the search term “leather jackets” in your Spotler Activate Search account. With the help of Clickrank though, you’ll automatically be showing summer leather jackets towards the top of the results in the summer and warmer jackets in the winter, as people tend to click on those items more during those seasons.

Push words will boost the document they are connected to with a factor 10, and an item will end up on top of the result list when the push word is used as a query. Multiple push words can be added to an item. Push words can also be added to multiple items. In that case, regular ranking will decide what item will be shown first.

A document has to have some sort of relevance before it can be boosted. When a visitor is searching for “dog”, but “dog” is not in the document, a boost will have no effect.

This is what push words look like in our sauce code:

Under ‘sorting’ in your conversion cockpit you’ll find the option for “Field boosting”. This allows you to use a value from an attribute in a document as a boost. Field boosting is relative to the Standard Spotler Activate Search Rank.
