# TikTok hashtag analysis toolset The tool helps to download posts and videos from TikTok for a given set of hashtags over a period of time. Users can create a growing database of posts for specific hashtags which can then be used for further hashtag analysis. It uses the [TikTokApi](https://github.com/davidteather/TikTok-Api) Python package to download the posts and uses [yt-dlp](https://github.com/yt-dlp/yt-dlp) to download the videos. [![PyPI version](https://badge.fury.io/py/tiktok-hashtag-analysis.svg)](https://badge.fury.io/py/tiktok-hashtag-analysis) ## Pre-requisites 1. Make sure you have Python 3.9 or a later version installed 2. Install the tool with pip: `pip install tiktok-hashtag-analysis` - Alternatively you can install directly from the latest version on GitHub: `pip install git+https://github.com/bellingcat/tiktok-hashtag-analysis` 3. Make sure [Playwright](https://playwright.dev/python/docs/intro) is properly installed by running the command `python -m playwright install` You should now be ready to start using it. ## About the tool ### Command-line arguments ``` usage: tiktok-hashtag-analysis [-h] [--file FILE] [-d] [--number NUMBER] [-p] [-t] [--output-dir OUTPUT_DIR] [--config CONFIG] [--log LOG] [--limit LIMIT] [-v] [--headed] [hashtags ...] Analyze hashtags within posts scraped from TikTok. positional arguments: hashtags List of hashtags to scrape optional arguments: -h, --help show this help message and exit --file FILE File name containing list of hashtags to scrape -d, --download Download video files corresponding to scraped posts --number NUMBER The number of co-occurring hashtags to analyze -p, --plot Plot the most common co-occurring hashtags -t, --table Print a table of the most common co-occurring hashtags --output-dir OUTPUT_DIR Directory to save scraped data and visualizations to --config CONFIG File name of configuration file to store TikTok credentials to --log LOG File to write logs to --limit LIMIT Maximum number of videos to download for each hashtag -v, --verbose Increase output verbosity --headed Don't use headless version of TikTok scraper ``` ### Structure of output data ``` $ tree ../data ../data ├── london │ ├── plots │ ├── posts.json │ └── media ├── newyork │ ├── plots │ ├── posts.json │ └── media └── paris │ ├── plots │ ├── posts.json │ └── media ``` The `data` folder contains all the downloaded data as shown in the tree diagram above. - Each hashtag has a folder with two subfolders `plots` and `media` that store plots of the most common co-occurring hashtags, and media downloaded from the posts. The posts are stored in the `posts.json` file, and downloaded media is stored as `.mp4` files (for videos) or audio and image files (for image galleries) in the `media` folder. ## How to use ### Post downloading Running the `tiktok-hashtag-analysis` command with the following options will scrape posts that contain the hashtags `#london`, `#paris`, or `#newyork`: tiktok-hashtag-analysis london paris newyork and will produce an output similar to the following log: $ tiktok-hashtag-analysis download london paris newyork Hashtags to scrape: ['london', 'paris', 'newyork'] Scraped 963 posts containing the hashtag 'london' Scraped 961 posts containing the hashtag 'paris' Scraped 940 posts containing the hashtag 'newyork' Successfully scraped 2864 total entries - The list of hashtags to scrape is specified as a positional argument ### Video downloading Running the `tiktok-hashtag-analysis` script with the following options will scrape trending posts containing the hashtag `#london`: `tiktok-hashtag-analysis london --download` - The `--download` flag specifies that video files for scraped posts should be downloaded Note that video downloading is a time and data rate consuming task, as a result we recommend using one hashtag at a time when using the `--download` flag to avoid complications. ## Analyzing results ### Most common co-occurring hashtags In addition to scraping data and downloading media, the `tiktok-hashtag-analysis` script can also analyze the frequencies of the most common co-occurring hashtags in a given set of posts. Assume we want to analyze the 20 most frequently co-occurring hashtags in the downloaded posts of the `#london` hashtag. - The results can be plotted and saved as a PNG file by executing the following command: `tiktok-hashtag-analysis london --number 20 --plot` which will produce a figure similar to that shown below:

Top 20 most frequent common hashtags in posts containing the #london hashtag

In the above plot, the highest occurrence is the `#fyp` hashtag, which is tagged in more than half of all posts containing the `#london` hashtag. - The results can be displayed in tabular form by executing the following command: `tiktok-hashtag-analysis london --number 20 --table` which will produce a terminal output similar to the following: ``` Co-occurring hashtags for #london posts Rank Hashtag Occurrences Frequency 0 london 881 1.0000 1 fyp 399 0.4529 2 uk 174 0.1975 3 foryou 168 0.1907 4 viral 152 0.1725 5 foryoupage 137 0.1555 6 fypシ 73 0.0829 7 funny 54 0.0613 8 tiktok 43 0.0488 9 trending 43 0.0488 10 british 41 0.0465 11 england 38 0.0431 12 xyzbca 34 0.0386 13 fy 33 0.0375 14 usa 33 0.0375 15 love 29 0.0329 16 comedy 25 0.0284 17 royalfamily 23 0.0261 18 queen 23 0.0261 19 queenelizabeth 22 0.0250 Total posts: 881 ``` The `Frequency` column shows the ratio of the occurrence to the total number of downloaded posts. ### Contributing To run the build-in tests in the `tests/` directory, first install the test dependency packages: ``` pip install .[dev] ``` and then run the tests using the following command: ``` pytest ``` This repo uses [black](https://github.com/psf/black) to format source code and [mypy](https://mypy.readthedocs.io/en/stable/) for static type checking.
