Your Search engine optimisation information to the ChatGPT API

ChatGPT introduced the rollout of its API (GPT 3.5 Turbo) on March 1. 

I’m bullish on ChatGPT’s utility for a number of completely different Search engine optimisation-related capabilities like key phrase analysis, native Search engine optimisation, content material, and hyperlink constructing. Having spent a lot time utilizing ChatGPT, I’m additionally painfully conscious of its limitations.

Whereas the API gained’t be a panacea (and the online interface is definitely a lot better for some duties), it may well assist tackle a few of the shortcomings of the online interface.

This text will present you find out how to maximize ChatGPT’s API with particular Search engine optimisation use instances.

How one can use the ChatGPT API

To leverage the ChatGPT API, you want to have the ability to entry the API within the first place. ChatGPT’s guardian firm OpenAI has in depth documentation for utilizing the API.

If you happen to’re seeking to be taught extra about constructing a device or interacting instantly with the API there’s additionally a great walk-through right here.

You too can use AppsScript to question the ChatGPT API in Google Sheets, which we’ll stroll by means of right here step-by-step.

No matter your strategy, you’ll want to start out by getting an API key.

Getting your ChatGPT API key

Upon getting an OpenAI account, you may generate your API key both by following this hyperlink whereas logged in or clicking View API keys within the profile dropdown:

ChatGPT - View API keys

Then click on Create new secret key.

ChatGPT - Create new secret key

Copy the API key you generated.

ChatGPT - API key generated

Connecting the ChatGPT API to Google Sheets

There’s an easy approach to join ChatGPT to Google Sheets (h/t Keith Mint).

First, create a brand new Google Sheet, then click on on Extensions and select Apps Script:

ChatGPT API - Google Sheets extension

You then paste the next code (along with your API key rather than YOUR API KEY):

const MAX_TOKENS = 800;
const TEMPERATURE = 0.9;

operate AI_ChatGPT(immediate, temperature = 0.4, mannequin = "gpt-3.5-turbo") {
  const url = "";
  const payload = {
    mannequin: mannequin,
    messages: [
      { role: "system", content: "You are a helpful assistant." },
      { role: "user", content: prompt },
    temperature: TEMPERATURE,
    max_tokens: MAX_TOKENS,
  const choices = {
    contentType: "software/json",
    headers: { Authorization: "Bearer " + SECRET_KEY },
    payload: JSON.stringify(payload),
  const res = JSON.parse(UrlFetchApp.fetch(url, choices).getContentText());
  return res.selections[0].message.content material.trim();

Click on save inside Apps Script:

ChatGPT API - Apps Script

Then you need to use the next operate format to use a immediate to a cell:


ChatGPT Google Sheet prompt formula

As Mint factors out in his article, you may as well reference a cell if you wish to have a number of cells use prompts that refer again to 1 cell (just like the title or matter of a weblog submit):

ChatGPT - Google Sheet prompt formula with multiple cells

Within the instance above, I used easy prompts just like the one pictured, then created a second paragraph for this matter. (We’ll stroll by means of extra particular purposes for the API shortly.) 

ChatGPT API pricing

Earlier than you begin leveraging the ChatGPT API for Search engine optimisation duties, it’s important to grasp the pricing.

The value for the gpt-3.5-turbo API (the ChatGPT API) is $0.002 per 1,000 tokens, which is 10x cheaper than the present GPT-3.5 API.

To raised perceive what the pricing truly winds up wanting like, it’s essential to perceive how tokens work.

ChatGPT API tokens

OpenAI has a good breakdown and a useful free tokenizer device that will help you decide what number of tokens a selected textual content will likely be and the way the textual content is damaged down (in case it’s essential to cut back the variety of tokens for a immediate or response).

Just a few key issues to remember:

  • By default, the API can return a most of 4,096 tokens.
  • Tokens are a illustration of how a lot textual content your immediate and response are. It is a key issue, as longer prompts can shorten your response output.
  • Textual content is translated into tokens and roughly breaks right down to round 4 characters in English.

OpenAI additionally supplied this useful breakdown of how tokens are calculated from textual content:

  • 1 token ~= 4 chars in English
  • 1 token ~= ¾ phrases
  • 100 tokens ~= 75 phrases


  • 1-2 sentence ~= 30 tokens
  • 1 paragraph ~= 100 tokens
  • 1,500 phrases ~= 2048 tokens

To get extra context on how tokens stack up, contemplate this:

  • Wayne Gretzky’s quote, “You miss 100% of the pictures you don’t take,” incorporates 11 tokens.
  • OpenAI’s constitution incorporates 476 tokens.
  • The transcript of the U.S. Declaration of Independence incorporates 1,695 tokens.

So when you used a brief immediate to generate a 1,500-word article, it might be lower than half a cent.

Particular API use instances for Search engine optimisation

The API can assist with numerous the identical Search engine optimisation-related duties because the ChatGPT internet interface, however the two have some vital variations, making some duties higher for one than the opposite.

Understanding that can make it easier to decide which to make use of for Search engine optimisation duties.

ChatGPT API vs. internet interface

The largest variations embody the next:

Scale and bulk duties

If you wish to combine ChatGPT with an present software or spreadsheet, you may want to make use of the API. 

Moreover, the API will likely be your pal if you wish to carry out a selected operate utilized throughout a number of cases (e.g., generate meta descriptions for a number of key phrases).

High-quality-tuning and relationship between prompts

Presently, ChatGPT’s API doesn’t help fine-tuning. If you happen to create a number of prompts by means of the API, they will not have a relationship. 

You may create a system message to use to a number of prompts and responses, however OpenAI has stated that these are regularly presently ignored by the gpt-3.5-turbo API. 

This implies when you’ve got a process that requires a number of prompts and for ChatGPT to maintain the context of a complete dialog, you may need to use the online interface.

Character limits

The API has a token restrict of 4,096 which interprets to round 16,384 characters per interplay for every immediate and response

Character limits for the online interface can differ, however typically, the immediate and response are restricted to round 2,048 characters, or 4,096. 

So for duties that require extra in depth prompts or extra vital responses, the API will likely be a greater choice. 

There are additionally extra choices for structuring prompts and duties in a manner that offers you a lengthier mixed output when you’re utilizing code slightly than one thing just like the Google Sheets integration.


Once more, the API is priced by utilization (and gives a free trial with $18 price of tokens), and the online interface presently gives a free model and a $20/mo. paid model. 

Instance ChatGPT API prompts

Let’s take a look at particular use instances the place you’d need to contemplate the API over the online interface.

Title tags and meta descriptions

An apparent use case the place the API is sensible is having ChatGPT generate title tags or meta descriptions at scale.

You need to use related prompts to those who work within the internet interface right here, however when you construction them correctly and lay out your spreadsheet proper, you may take the primary immediate after which shortly apply that to a number of URLs or key phrases: 

ChatGPT API - Title tags and meta descriptions

Be aware that the free plan significantly is price restricted, so you might have errors the place the cells day out, during which case it’s essential to delete and re-paste:

ChatGPT API - Google Sheets errors

And as all the time, understand that:

  • ChatGPT cannot crawl the online, so it is both utilizing prior data of a URL from the coaching interval or an assumption concerning the URL based mostly on phrases within the URL to generate solutions
  • ChatGPT’s output can typically be fallacious or deceptive and must be edited.

You need to use this identical format for title tags. (I am going to have an article focusing particularly on utilizing ChatGPT to generate and replace title tags popping out quickly).

Longer content material and submit outlines

You need to use the online interface in ChatGPT to create chunks of content material and descriptions fairly simply.

If you wish to make an extended article or if you are going to create a collection of outlines on completely different matters, nevertheless, it may be a clunky expertise.

The API is smoother for these duties.

First, you may chunk off a submit you wrote into sections. Then line up the sections and pull your immediate down:

ChatGPT API - longer content and post outlines

Alternatively, you might have ChatGPT generate a number of outlines that you just then have a author (or writers) fill in:

ChatGPT API - article outlines

Then, you might have the API write the content material one part at a time:

ChatGPT API - write article sections

Once more, right here you might take these prompts, load them one after the other throughout the define (altering every immediate for the suitable part), after which simply pull the identical formulation throughout a number of outlines and have numerous textual content particular to the subsections of every submit generated.

My expertise is that this helps you avoid token limits, and even pedestrian prompts just like the one above mixed with having ChatGPT create an overview will generate higher content material than when you ask the device to “write a weblog submit.” 

Past that, you may additional enhance content material high quality by doing issues like:

  • Ask it to incorporate particular phrases (both since you need them on the web page otherwise you need to add inner hyperlinks for that phrase).
  • Feed it statistics or quotes to work into particular sections of the submit. (That is significantly useful when you’ve got a subject that requires up-to-date techniques and statistics, on condition that GPT-3 was not skilled on current information.)
  • Tweak your prompts to output the tone and formatting you need (extra on this shortly).

And, as all the time, layer on human enhancing.


There are a number of FAQ-related capabilities the API can assist with.

First off, you may generate a listing of FAQ inquiries to be related to a weblog submit:


Subsequent, you may have the ChatGPT API reply these (once more: proceed with warning on the subject of output high quality and accuracy):

ChatGPT API - FAQs - answers


You too can have ChatGPT generate schemas for you throughout a number of pages. 

On this case, we will apply FAQ schema to the FAQs it created for us:

ChatGPT API - Schema

Convert content material to HTML

One other cool use case for ChatGPT is to transform textual content to HTML. 

First, let’s convert our submit from textual content to HTML:

ChatGPT API - Convert content to HTML

Just a few issues to notice right here:

  • As you may see, the headers in every part had been initially formatted with paragraph tags. I fastened this within the immediate by including, “Format the header of the part as an h2, and another headlines on this part as an h3.”
  • I wasn’t in a position to mix all the submit (which was round 1100 phrases) into one cell to be transformed to HTML, so I needed to chunk it off and gave particular directions in my immediate for every cell to verify ChatGPT did not layer within the formatting for a complete HTML doc in each cell.
  • You might also get some wonky formatting, like extra quotes you did not anticipate within the output. 

As with all features of ChatGPT, hold refining your prompts and all the time test the output.

Now that we now have our submit in HTML, we will begin to do some cool issues with inner linking.

We are able to inform ChatGPT so as to add inner hyperlinks from particular phrases to particular pages wherever within the HTML we simply generated:

ChatGPT API - Add internal links

If we had been making a cluster of pages, we might create guidelines particular to every web page and apply them to the related HTML.

This fashion, the whole lot we generate is interlinked the way in which we wish, the HTML is able to go, and the FAQ schema is added appropriately.

I attempted to create a rule that was a bit extra sophisticated, asking ChatGPT to hyperlink phrases. Here’s what I added to my immediate:

  • “Any time you see the phrases making and chuckle inside 5 phrases of one another, create a hyperlink with these two phrases and the entire phrases in between them to”

Right here is the hyperlink that was added:

ChatGPT API - Wrong hyperlinks

That is not what I requested for, and likewise, it did not hyperlink each occasion of stand-up as I requested it to.

I am going to have to refine my prompts and test my outputs.

Outreach templates

If you happen to’re reaching out to a number of locations for hyperlink outreach or visitor submit placements, you need to use the ChatGPT API to create a number of outreach templates for you:

ChatGPT API - Outreach templates

When you have completely different sorts of templates, get artistic with making use of these prompts throughout completely different outreach targets.

Utilizing the online interface and the API in tandem (a.okay.a., convey your prompts)

Two issues are true:

  • The API is healthier for bigger initiatives and performs many prompts concurrently.
  • The online interface is regularly higher at getting you to a superb output since you may shuttle with ChatGPT to provide context, assessment the output, present suggestions, and many others.

One approach to get the perfect of each worlds is to create your immediate within the internet interface after which apply it to a number of objects through the API.

Let’s take a look at a selected instance from this submit. My inner linking immediate did not work through the API. It is difficult to troubleshoot through the API as a result of you may’t give ChatGPT suggestions or ask why the immediate failed.

Enter, immediate era through the online!

My typical ChatGPT course of is to: 

  • Give it chunks of context.
  • Examine for understanding. 
  • Assessment the output for errors and provides it extra suggestions to realize my desired outcome.

To have the ability to do that for inner linking guidelines, let’s begin with the online interface to wash up our ChatGPT immediate.

First, I need to give ChatGPT some context. (Bear in mind: ChatGPT does not find out about its personal API!) 

I need to give it details about the API, share the HTML I am beginning with, share the immediate I used, and share the output I acquired after which ask ChatGPT to diagnose the difficulty and rewrite the immediate for me.

Let’s have a look at the way it goes:

ChatGPT web - Prompt creation

If you happen to do not pre-empt it, ChatGPT will repeatedly interrupt you to fireplace (regularly irrelevant) solutions and solutions (like an keen pupil who did not do the studying).

I copied and pasted the textual content from this web page in 4 prompts, the HTML I used to be making an attempt so as to add hyperlinks to, the total Sheets operate I might used, and the output I might gotten.

Subsequent, I lastly shared the difficulty with the output:

ChatGPT web - Prompt creation for Google Sheets

After which ChatGPT fastened the immediate for me.

ChatGPT web - Fixed prompt Google Sheets

Effectively, it wasn’t truly fastened.

ChatGPT web - Prompt syntax error

ChatGPT is relentlessly well mannered even when you’re getting a bit testy, and after I shared the immediate, it analyzed it for me:

ChatGPT Web Prompt Feedback 800x557

The solutions on HTML measurement are good ones, however I used to be nonetheless getting the error:

ChatGPT web - Google Sheet max character limit

This time, the immediate labored!

To handle the max tokens challenge, I can go to Apps Script to regulate that quantity:

ChatGPT API - Google Sheet fix character limit

Or clearly, if I am not utilizing Sheets, it is not prone to be a problem (till I hit the 4096 tokens).

Get artistic and search for options

Search engine optimisation purposes for the ChatGPT API go effectively past what’s listed right here. 

If you happen to’re looking out for methods to make use of the platform and might get artistic you may discover many extra purposes like:

  • Programmatic options: You may transcend Google Sheets to search out thrilling and scalable makes use of for the ChatGPT API.
  • Combining a number of APIs: Take into consideration the way you may be capable of use the ChatGPT API in unison with APIs like Google Search Console, Ahrefs, Semrush or related. What issues do you need to clear up? 
  • Extra environment friendly or higher workflows: Take inventory of the duties you and your crew full each day. Are there objects that ChatGPT’s API might be able to both mean you can just do as effectively however extra effectively, or to enhance your work product round?

With the current launch of GPT-4, extra alternatives for leveraging the platform will possible proceed to crop up.
