Here is a typical and fascinating duplicate content material drawback.

Advanced Duplicate Content Consolidation with Python

You have a retailer like David Yurman with merchandise obtainable in several coloration variations and chooses to show every product coloration by itself URL.

Each product/coloration URL would usually have the identical content material however change the primary product picture, which isn’t sufficient of a distinction to set them aside.

Should you canonicalize all product variants to at least one and consolidate duplicate content material?

Or must you rewrite the product title, description, and many others. to maintain every model separate and distinctive?

When you consolidate pages with principally the identical content material, you usually find yourself with greater efficiency. This illustration from Google reveals why.

Advanced Duplicate Content Consolidation with Python

You are not directly constructing hyperlinks to the canonical pages.

When you’ve gotten pages with principally the identical content material, they compete within the SERPs for a similar phrases and most of them would get filtered at question time. Each one of many pages filtered accumulates hyperlinks that go to waste.

However, right here is an fascinating case. What if folks particularly seek for content material solely obtainable in among the pages?

In this case, it might not be clever to consolidate these as a result of we might lose the related rankings.

Let’s deliver this house with a concrete instance utilizing SEMrush.

David Yurman has merchandise in a minimum of six predominant colours: sterling silver, black titanium, rose gold, yellow gold, white gold, and inexperienced emerald.

It is feasible that there are coloration particular searches in Google that result in product pages. If that’s the case, we don’t need to consolidate these pages to allow them to seize the related coloration particular search site visitors.

Here is an instance SEMrush search that may assist us examine if that’s the case.

Advanced Duplicate Content Consolidation with Python

For instance, now we have 489 natural key phrase rankings for sterling silver, 863 for rose gold, and simply 51 for black titanium.

I additionally checked utilizing cell as a tool and acquired 30 for sterling silver, 77 for rose gold, and solely 11 for black titanium.

Most websites would both maintain coloration URLs separate like David Yurman or consolidate colours into one web page on the URL degree or utilizing canonicals.

At least, from an search engine optimization efficiency perspective, it doesn’t appear to be maintaining black titanium as separate URLs is a very sensible choice given the low variety of searches.

But, what if we might discover an excellent center floor?

What if we might consolidate some product URLs and never others?

What if we might carry out these selections primarily based on efficiency knowledge?

That is what we’re going to learn to do on this article!

Here is our plan of motion:

  • We will use OnCrawl’s crawler to gather all of the product pages and their search engine optimization meta knowledge (together with canonicals).
  • We will use SEMrush to assemble coloration particular search phrases and corresponding product pages.
  • We will outline a easy clustering algorithm to group (or not group) merchandise relying on whether or not they have coloration searches.
  • We will use Tableau to visualise the clustering modifications and perceive the modifications higher.
  • We will add our experimental modifications to the Cloudflare CDN utilizing the RankSense app.

1. Getting Product Page Groups Using OnCrawl

I began a web site crawl utilizing the primary website URL: https://www.davidyurman.com.

Advanced Duplicate Content Consolidation with Python

As I’m solely taken with reviewing U.S. merchandise, I downloaded the US merchandise XML sitemap, transformed it to a CSV file, and uploaded it as a zipper file.

Advanced Duplicate Content Consolidation with Python

I added the present rel=canonical as a column and exported the checklist of two,465 URLs.

2. Getting Color Search Queries to Product Pages Using SEMrush

I put collectively an preliminary checklist of colours: sterling silver, black titanium, rose gold, yellow gold, white gold, inexperienced emerald. Then exported six product lists from SEMrush.

three. Clustering Product URLs by Product Identifier

We are going to make use of Google Colab and a few Python scripting to do our clustering.

First, let’s import the OnCrawl export file.

Then, we will additionally import the SEMrush information with the colour searches.

Advanced Duplicate Content Consolidation with Python

I attempted a few concepts to extract the product ID from the URLs, together with utilizing OnCrawl’s content material extraction function, however settled on this one which extracts it from the URL.

Next, that is how we will add the product ID column to our Dataframe and group the URLs to carry out the clustering.

In this clustering train, you may see some product IDs with no canonicals. We are going to repair that by including self-referential canonicals to these URLs.

Let’s export the info body to a CSV file and import into Tableau for additional evaluation. In Tableau, we will visualize the present canonical clusters higher.

In Tableau, full these steps:

This is what the setup appears to be like like.

Each sq. represents a product ID cluster. The larger ones have extra URLs. The calculated subject “canonicalized” makes use of colours to inform if a cluster is canonicalized or self-referential.

We can see that in its present setup, the David Yurman merchandise are principally self-referential with only a few clusters canonicalized (blue squares).

Here is a more in-depth look.

This could be a superb setup if most merchandise obtained search site visitors from coloration particular product searches. Let’s see if that’s the case subsequent.

four. Turning Canonical Clusters to Canonicalized

We are going to carry out an intermediate step and power all product teams to canonicalize to the primary URL within the group.

This is sweet sufficient for instance the idea, however for manufacturing use, we might need to canonicalize to the preferred URL within the group. It may very well be probably the most linked web page or the one with probably the most search clicks or impressions.

After we replace our clusters, we will return to Tableau, repeat the identical steps as earlier than and evaluation the up to date visualization.

Advanced Duplicate Content Consolidation with Python

You can see that not one of the clusters are self-referential now as ought to be the case as a result of we power them to not be so. All of them canonicalize to just one URL.

5. Turning Some Canonical Clusters to Self-Referential

Now, on this remaining step, we are going to be taught what number of clusters ought to be self-referential.

As all teams canonicalize to at least one URL now, we solely want to interrupt these cluster the place URLs have search site visitors for coloration phrases. We will change the canonicals to be self-referential.

First, let’s import all of the SEMrush information we exported right into a dataframe, and convert the URLs right into a set for simple checking.

The subsequent step is to replace the canonicals just for the teams that match.

After this course of, we will return to Tableau and evaluation our remaining clusters.

Advanced Duplicate Content Consolidation with Python

Surprisingly, we solely have one cluster that we have to replace, which signifies that David Yurman is leaving some huge cash on the desk with their present setup that depends on self-referential canonicals.

6. Implementing Experimental Changes in Cloudflare with RankSense

Performing selective and experimental modifications like this one on a conventional CMS won’t be sensible, require severe dev work or could be a tough promote with out proof this could work.

Fortunately, these are the varieties of modifications which are simple to deploy in Cloudflare utilizing our app and with out writing backend code. (Disclosure: I work for RankSense.)

We will copy our proposed canonical clusters to a Google Sheet. Here is an instance:

Advanced Duplicate Content Consolidation with Python

Assuming David Yurman used Cloudflare and had our implementation app put in, we might merely add the sheet, add some tags to trace efficiency and submit it to get the modifications to staging preview or manufacturing.

Advanced Duplicate Content Consolidation with Python

Finally, we might manually evaluation the canonicals are working as anticipated utilizing our 15 Minute Audit Chrome extension, however to make sure, we should always run one other OnCrawl crawl to verify all modifications are in place.

I noticed duplicate meta descriptions and I’m positive they’ve extra search engine optimization issues to handle.

Advanced Duplicate Content Consolidation with Python

If this concept proves to work effectively for them, they will confidently proceed to fee the dev work to get this carried out on their website.

Resources to Learn More

It is admittedly thrilling to see the Python search engine optimization neighborhood rising so shortly in the previous few months. Even Google’s John Mueller is beginning to discover.

Some folks locally have been performing some unbelievable work.

For instance, JR Oakes shared the outcomes of a content material era venture he has been engaged on for two years!

Alessio constructed a cool script that generates an interactive visualization of “people also asked” questions.

Overall, whereas it’s good to obtain reward for my work like those under, I get much more excited in regards to the rising physique of labor the entire neighborhood is constructing.

We are rising stronger and extra credible every day!
