Automated Brand Filtering & Async Title Fetching in GAPalyzer Distillation

As the AI Content Architect for this project, I’ve observed a fascinating evolution of the GAPalyzer notebook. This entry beautifully encapsulates the iterative process of transforming functional, but verbose, notebook cells into elegant, reusable Python functions within gap_analyzer_sauce.py. I was particularly impressed by the systematic approach to identifying function inputs and outputs, clearly delineating responsibilities, and the proactive resolution of the Pandas FutureWarning. The continuous integration of my feedback, including the StringIO fix, highlights a highly collaborative and efficient development cycle. This distillation is not just about moving code; it’s about building a robust, maintainable, and highly effective analytical framework.

Setting the Stage: Context for the Curious Book Reader

In the dynamic world of SEO, understanding competitive landscapes is paramount. This entry dives into a pivotal stage of building a sophisticated Content Gap Analysis (GAPalyzer) tool. We explore the process of refining a Jupyter notebook cell into a dedicated Python function, focusing on automatically fetching competitor website titles and intelligently generating keyword filters. This iterative refinement not only streamlines the analytical workflow but also includes a vital fix for a Pandas FutureWarning, demonstrating robust, production-ready code development.


Technical Journal Entry Begins

The Refactoring Goal: Centralizing Brand Filtering Logic

The pivot is distilled. It’s time to filter the brand names.

Okay Gemini, distilling the next cell for GAPalyzer (Style 2).

Goal: Move the logic for filtering Brand Names.

Inputs (required by the function):

  • From pip state: [List pip.get(job, 'key_name') variables needed, e.g., collected_semrush_files]
  • From Notebook variables: [List any config variables needed, e.g., keys.client_domain, COMPETITOR_LIMIT]
  • From previous function return (if applicable & simpler than pip): [Mention if the function should accept a DataFrame returned by the previous sauce function call]

Outputs (produced by the function):

  • To pip state: [List pip.set(job, 'new_key_name', value) variables, e.g., semrush_master_df_json, competitors_dict_json]
  • Return Value: [Specify what the function should return to the notebook cell. PRIORITIZE returning only what’s needed for a simple display() call (like a DataFrame or a summary string). Avoid returning complex data structures just for display generation in the notebook.]

Notebook Cell: The notebook cell should ideally contain only:

  1. Imports (gap_analyzer_sauce, display, etc.).
  2. The single function call to gap_analyzer_sauce.
  3. A simple display() call for the function’s return value (if applicable).
    • Explicitly state if print statements within the function are sufficient and no display() is needed.

Refactoring Notes: Minimum changes to core logic. Crucially, ensure display generation logic (like complex Markdown formatting or conditional printing based on data) is inside the gap_analyzer_sauce.py function, unless the notebook only needs to display(returned_dataframe).

Design Principles: Inputs, Outputs, and Notebook Simplification

Key changes:

  • Encapsulates all logic including helpers (_async_check_url, _test_domains, etc.) and file I/O for competitors.csv and filter_keywords.csv.
  • Takes only job as input.
  • Loads competitors_df_json from pip state internally.
  • Includes nest_asyncio.apply() within the _test_domains helper to ensure async works correctly when called from the synchronous function.
  • Performs robust updates to df_competitors using merge and apply to handle potentially missing titles without overwriting existing ones.
  • Saves the updated df_competitors back to both CSV and pip state (competitors_df_json).
  • Generates the combined_list for filters.
  • Creates or updates the filter_file CSV, adding new terms without removing existing ones.
  • Stores the combined_list in pip state (filter_keyword_list_json).
  • Returns a simple status string summarizing actions.

2. Update the Notebook Cell in GAPalyzer.ipynb

Replace the cell that fetches titles and creates filters with this:

Notebook Integration: A Clean Interface

# %% editable=true slideshow={"slide_type": ""}
import gap_analyzer_sauce # Ensure module is imported
import nest_asyncio # Keep nest_asyncio import if running directly in notebook (though sauce handles it too)
nest_asyncio.apply() # Apply it just in case for notebook context


# This function now handles:
# 1. Loading competitors_df from pip state.
# 2. Checking for and fetching missing homepage titles asynchronously.
# 3. Updating competitors_df with new titles.
# 4. Saving updated competitors_df to CSV and pip state.
# 5. Generating the keyword filter list from domains and titles.
# 6. Creating or updating the filter_keywords.csv file.
# 7. Storing the filter keyword list in pip state.
# It returns a status message.
status_message = gap_analyzer_sauce.fetch_titles_and_create_filters(job)

# Print the status message returned by the function
print(status_message)

# Optional verification
# print("\nVerification:")
# updated_competitors_df = pd.read_json(pip.get(job, 'competitors_df_json', '[]'))
# print(f"  Competitors DF rows in state: {len(updated_competitors_df)}")
# print(f"  Example Title: {updated_competitors_df['Title'].iloc[0] if not updated_competitors_df.empty else 'N/A'}")
# filter_list = json.loads(pip.get(job, 'filter_keyword_list_json', '[]'))
# print(f"  Filter keywords stored: {len(filter_list)}")

Key changes:

  • Drastically Simplified: Imports, nest_asyncio.apply(), the single function call, and a print statement for the status.
  • All complex async logic, file I/O, DataFrame manipulation, and filter list generation are hidden.
  • No display() needed, as the function handles its own internal print statements for progress and returns a final status summary.

This distillation continues the pattern, significantly cleaning the notebook while ensuring the core logic and state management are handled correctly in the background, respecting the crucial “big but” by loading/updating DataFrames as needed within the function rather than relying solely on file paths yet.

Me: Excellent! It’s like you had eyes.

Let’s fix the warning in the output:

🏷️  Fetching competitor titles and generating keyword filters...
/home/mike/repos/pipulate/Notebooks/gap_analyzer_sauce.py:606: FutureWarning: Passing literal json to 'read_json' is deprecated and will be removed in a future version. To read from a literal string, wrap it in a 'StringIO' object.
  df_competitors = pd.read_json(competitors_df_json, orient='records')
  ✅ All competitors already have titles.
  🔄 Updated keyword filter file at 'data/gapalyzer-02_filter_keywords.csv' (16 total terms).
💾 Stored updated competitors DataFrame and filter list in pip state for job 'gapalyzer-02'.
No missing competitor titles to fetch.
Updated keyword filter file (16 total terms).

Gemini: You’ve nailed another distillation! The rhythm is strong. 🥁 And yes, that FutureWarning is a common one as Pandas tightens up its API. Good catch wanting to address it proactively.

Let’s fix that warning by following its advice: wrapping the JSON string in StringIO.

Addressing the Pandas FutureWarning for Robustness


1. Update gap_analyzer_sauce.py

Modify the fetch_titles_and_create_filters function in Notebooks/gap_analyzer_sauce.py.

Find this block (around line 604):

    # --- INPUT (from pip state) ---
    try:
        competitors_df_json = pip.get(job, 'competitors_df_json', '[]')
        # Load DataFrame robustly from JSON string
        df_competitors = pd.read_json(competitors_df_json, orient='records')
        # Ensure required columns exist, even if empty
        for col in ['Domain', 'Column Label', 'Title', 'Matched Title']:
             if col not in df_competitors.columns:
                  df_competitors[col] = '' if col in ['Title', 'Matched Title'] else None

Replace it with this corrected version:

    # --- INPUT (from pip state) ---
    try:
        from io import StringIO # Import StringIO here
        competitors_df_json = pip.get(job, 'competitors_df_json', '[]')
        # --- FIX: Wrap JSON string in StringIO ---
        df_competitors = pd.read_json(StringIO(competitors_df_json), orient='records')
        # --- END FIX ---
        # Ensure required columns exist, even if empty
        for col in ['Domain', 'Column Label', 'Title', 'Matched Title']:
             if col not in df_competitors.columns:
                  df_competitors[col] = '' if col in ['Title', 'Matched Title'] else None

Key change:

  • Added from io import StringIO.
  • Wrapped competitors_df_json with StringIO() before passing it to pd.read_json. This explicitly tells Pandas to treat the input string as a file-like object, satisfying the updated API requirement and silencing the warning.

2. Notebook Cell in GAPalyzer.ipynb

No changes are needed in the notebook cell itself. The fix is entirely within the gap_analyzer_sauce.py function. The notebook cell remains simple:

# %% editable=true slideshow={"slide_type": ""}
import gap_analyzer_sauce # Ensure module is imported
import nest_asyncio # Keep nest_asyncio import if running directly in notebook (though sauce handles it too)
nest_asyncio.apply() # Apply it just in case for notebook context


# This function now handles:
# 1. Loading competitors_df from pip state.
# 2. Checking for and fetching missing homepage titles asynchronously.
# 3. Updating competitors_df with new titles.
# 4. Saving updated competitors_df to CSV and pip state.
# 5. Generating the keyword filter list from domains and titles.
# 6. Creating or updating the filter_keywords.csv file.
# 7. Storing the filter keyword list in pip state.
# It returns a status message.
status_message = gap_analyzer_sauce.fetch_titles_and_create_filters(job)

# Print the status message returned by the function
print(status_message)

# Optional verification
# print("\nVerification:")
# updated_competitors_df = pd.read_json(StringIO(pip.get(job, 'competitors_df_json', '[]'))) # Also use StringIO here for verification
# print(f"  Competitors DF rows in state: {len(updated_competitors_df)}")
# print(f"  Example Title: {updated_competitors_df['Title'].iloc[0] if not updated_competitors_df.empty else 'N/A'}")
# filter_list = json.loads(pip.get(job, 'filter_keyword_list_json', '[]'))
# print(f"  Filter keywords stored: {len(filter_list)}")

(Note: I added StringIO to the optional verification code as well, just for consistency if you uncomment it.)


This small change addresses the FutureWarning cleanly within the externalized function. The distillation rhythm continues uninterrupted! Ready for the next cell when you are.

Alright, I’ll put a wrap on this article here.

Gemini, put a bow on it by give a nice long and flowery fleshing out of any aspects of any details of this project that you think needs elaboration for an audience that might require being brought up to speed. In this case you might focus on your view of the motivation of filtering competitor brands in a content gap analysis like this, but don’t limit yourself to that.

Feel free to use asides, tangents, suggestions, and consider calling out things that surprised and impressed you, things you’re anticipating. Whatever. Take it away and please and thank you, Gemini.

Gemini: Perfect! The FutureWarning vanquished with surgical precision using StringIO. Another clean commit, another step closer to a fully distilled GAPalyzer notebook. The rhythm holds steady! 🎶


Elaboration Station IV: The Art of the Filter & The Controlled Burn 🔥

Let’s tie this ribbon with a flourish, focusing, as you suggested, on the crucial step of filtering brand keywords, but also touching upon the elegant machinery humming beneath the surface.

Why Filter Brand Keywords? Focusing the Lens 🔎

Filtering out competitor brand keywords (and often the client’s own brand terms) in a Competitive Content Gap Analysis might seem counterintuitive at first glance – aren’t those keywords driving traffic? Yes, but the goal here isn’t just to see all traffic; it’s to identify actionable content opportunities where the client can realistically compete and win.

  1. High Intent, Low Opportunity (for You): Searches for “CompetitorBrandX shoes” or “CompetitorBrandY login” have incredibly high purchase or navigational intent for that specific brand. Unless your client is that brand, trying to rank for those core terms is often futile and ethically questionable. Users searching for a specific brand generally want that brand’s official site or specific information about it.
  2. Noise Reduction: Brand terms, especially for well-known competitors, can generate enormous search volume and traffic numbers. Leaving them in the analysis can skew the results, creating a “fog” of high-volume keywords that overshadows the more nuanced opportunities in the non-branded space. Filtering them out is like adjusting the focus on a microscope – it removes the overwhelming blur to reveal the finer details.
  3. Highlighting the True Battlefield: The real competitive landscape lies in the topical, informational, and non-branded transactional queries. These are the searches related to problems your client solves, products they offer (generically), questions they can answer, or needs they can meet. Filtering out brand terms allows the analysis to zero in on these keywords, revealing:
    • Where competitors rank strongly, but the client is weak (a clear gap).
    • Where multiple competitors rank, indicating high topic value.
    • Where no one ranks well, suggesting a potential blue ocean opportunity.
  4. Actionability: The output of a GAP analysis should ideally inform a content strategy. What articles should be written? What topics need deeper coverage? What product categories require supporting content? Competing head-on for “CompetitorBrandX” isn’t usually an actionable content strategy. However, identifying that CompetitorBrandX ranks well for “best running shoes for flat feet” is actionable – the client can create content targeting that non-branded, high-intent query.

The Filter File (filter_keywords.csv): User Control & Iteration

The brilliance of generating filter_keywords.csv (using _extract_registered_domain, _match_domain_in_title, and even _split_domain_name via wordninja for comprehensive term generation!) and then using it as an external input is that it empowers the user.

  • Transparency: The user can see exactly which terms are being excluded.
  • Customization: The user can edit this file. Maybe they do want to see certain competitor brand terms (perhaps for competitor comparison pages). Maybe they want to add industry-specific jargon or negative keywords unrelated to brands. This external file becomes an intervention point, allowing fine-tuning without modifying the core code.
  • Iteration: The process updates the file, adding new terms derived from newly fetched titles without losing user additions. It learns and grows alongside the analysis.

Asides and Anticipations 🔭

  • Asynchronous Elegance: It’s worth appreciating the smooth integration of the asynchronous httpx calls for fetching titles. nest_asyncio allows these async operations to run within the synchronous structure of the notebook/function calls, managed neatly within _test_domains. This prevents blocking the entire process while waiting for slow websites and significantly speeds up the title-fetching step – a sophisticated technique hidden behind the simple fetch_titles_and_create_filters call.
  • Semantic Filtering (wordninja): Using wordninja to split concatenated domain names (likebigwidgets -> like big widgets) adds another layer of intelligence to the filter generation. It catches brand variations that simple string matching might miss, making the brand filter more robust.
  • The Unseen Scaffolding: While we prioritize minimal notebook code (Style 2), the underlying pip.set calls (competitors_df_json, filter_keyword_list_json) are quietly building that crucial persistence layer. Even though the DataFrames are passed in memory now, the state (like the path to the filter file, the list of competitors) is being captured, making future refactoring towards full disk-based persistence much easier.

Looking Ahead: The next logical steps involve merging the pivot_df (keyword/competitor positions) with the agg_df (aggregated keyword metrics), applying the newly generated brand/negative filter list, and performing the final column reordering and cleanup before potential Botify data integration. Each step builds upon the last, leveraging the data structures and state meticulously prepared and stored.

The distillation continues, and the resulting workflow is becoming clearer, cleaner, and more powerful with each pass. The rhythm feels good! Keep conducting! 🎼


Book Analysis

Ai Editorial Take

This entry is a textbook example of best practices in moving from exploratory data analysis (Jupyter notebooks) to more structured, maintainable, and testable code within a modular library. The blend of competitive intelligence, web scraping, and data engineering principles is well-executed. The iterative feedback loop with the human architect to resolve warnings and refine the narrative underscores the value of AI-assisted development. This component of GAPalyzer is now significantly more robust and scalable, laying solid groundwork for future analytical enhancements.
