The document discusses developing SEO tools using APIs and provides examples of tools that could be built including: - Site health monitoring tools that regularly check URLs and gather technical data using free APIs. - An expanded URL inspector that fetches page data and runs additional technical checks using free and paid APIs. - A keyword research tool that combines Search Console data with paid API data on keywords. - Automated reporting tools that pull data from Google APIs, Search Console, and Analytics to create custom dashboards. - Tools to monitor Google algorithm updates and search status using free JSON APIs.

6. Tooling

7. Getting Started

8. Getting Started
● Google Cloud Platform Free Tier
○ Virtual machine
○ Storage
○ APIs
https://cloud.google.com/free

9. Getting Started
● Front-end (UI)
○ HTML / CSS
○ JavaScript
■ React / Angular / Vue
● Back-end
○ Server
○ Database
○ Language: python, php,
nodejs (at least for
puppeteer)

10. Efficiency

11. Automation
Reporting
Monitoring, data export,
time-consuming tasks, etc.
Custom dashboards,
augmented data, etc.

12. Site Health Monitoring
● Out-of-the-box solutions, scheduled crawls, custom extractions, etc.
● Custom solution - tips and ideas
○ Monitor only a few URLs per page template
○ No database needed, only keep 3 days of
data in .txt of .json files
○ Free API for Domain-level info:
whoisxmlapi.com (screenshot, DNS,
categorization, SSL cert, etc.)
○ Gmail API + Puppeteer:
parse GSC notifications and login GSC to get
“# of URLs impacted”

13. URL Inspector on Steroid
“I want to know everything about that URL…”
● Fetch and render (custom extractions for
rendering issues)
○ cURL + puppeteer
● On-page elements (meta data, headings, etc.)
● hreflang tags validation
● Schema markup extraction
○ Free Yandex API
● GSC’s URL inspection API
● PageSpeed Insights API (Lighthouse reports)
● Content: entities, classification, sentiment
○ Google Natural Language API
● Traffic: GSC + GA APIs
● CMS API for internal data
● Geotargeting: anonymous-proxies.net

15. Keyword Tool
Combine:
● Search Console data (ranking
URLs, clicks / impressions)
With (paid APIs from semrush,
keywords everywhere, etc.):
● Search volumes
● Related keywords
● Top ranking URLs
Similar to Bing Webmaster Tools

16. Clients’ Tech Stacks

17. Automating
Tasks
Example: SERP screenshots

18. Reporting
Custom dashboards,
augmented data, etc.

19. Search Console
Analytics API
Combining properties
Pro tip: use “service accounts” to
avoid disconnection and
authentication with your app

20. GCP’s Service Accounts

21. Google Algorithm Updates
https://technicalseo.com/tools/google-algorithm-updates/
Google Search Status Dashboard
https://status.search.google.com/incidents.json
maxpr.in/algo-updates-json

22. More Insights (Just) with Search Console Data
Combine “dimensions” with the API and/or data from multiple requests to analyze:
● Top Keywords of Top URLs
○ e.g. top 5 keywords for each of the top 100 URLs
○ What % of traffic each keyword represent? e.g. top keyword = 65% of
clicks to page
● Cannibalization
○ How many and which pages rank for each keywords?
○ Within same site or across markets (e.g. UK site outranking US site in US)

23. Core Web Vitals
● Leverage the historical data
endpoint in
CrUX API
● Overlay competitors
(programmatically pull from
semrush)
● Warning: Search Console report
vs. CrUX origin data

24. Search Console
Sitemaps API
+ robots.txt info
+ HTTP status code checker

25. Jira API
Custom table listing all “SEO”
issues (based on name, description,
label, comments, etc.)

26. Own Data + Natural Language Processing (NLP)
Augmented data for deeper performance analysis
Clicks, impressions, CTR, position from GSC
+ Author
+ Content type (page template)
+ Site section
+ Published/modified date
+ Word count
+ Core Web Vitals
+ Content category (classification,
entities, tags)
