``advertools``: productivity & analysis tools to scale your online marketing
============================================================================
| A digital marketer is a data scientist.
| Your job is to manage, manipulate, visualize, communicate, understand,
and make decisions based on data.
You might be doing basic stuff, like copying and pasting text on spread
sheets, you might be running large scale automated platforms with
sophisticated algorithms, or somewhere in between. In any case your job
is all about working with data.
As a data scientist you don't spend most of your time producing cool
visualizations or finding great insights. The majority of your time is spent
wrangling with URLs, figuring out how to stitch together two tables, hoping
that the dates, won't break, without you knowing, or trying to generate the
next 124,538 keywords for an upcoming campaign, by the end of the week!
``advertools`` is a Python package that can hopefully make that part of your job a little easier.
Installation
------------
.. code:: bash
pip install advertools
# OR:
pip3 install advertools
SEM Campaigns
-------------
The most important thing to achieve in SEM is a proper mapping between the
three main elements of a search campaign
**Keywords** (the intention) -> **Ads** (your promise) -> **Landing Pages** (your delivery of the promise)
Once you have this done, you can focus on management and analysis. More importantly,
once you know that you can set this up in an easy way, you know you can focus
on more strategic issues. In practical terms you need two main tables to get started:
* Keywords: You can `generate keywords <https://advertools.readthedocs.io/en/master/advertools.kw_generate.html>`_ (note I didn't say research) with the
`kw_generate` function.
* Ads: There are two approaches that you can use:
* Bottom-up: You can create text ads for a large number of products by simple
replacement of product names, and providing a placeholder in case your text
is too long. Check out the `ad_create <https://advertools.readthedocs.io/en/master/advertools.ad_create.html>`_ function for more details.
* Top-down: Sometimes you have a long description text that you want to split
into headlines, descriptions and whatever slots you want to split them into.
`ad_from_string <https://advertools.readthedocs.io/en/master/advertools.ad_from_string.html>`_
helps you accomplish that.

SEO
---
Probably the most comprehensive online marketing area that is both technical
(crawling, indexing, rendering, redirects, etc.) and non-technical (content
creation, link building, outreach, etc.). Here are some tools that can help
with your SEO
* `SEO crawler: <https://advertools.readthedocs.io/en/master/advertools.spider.html>`_
A generic SEO crawler that can be customized, built with Scrapy, & with several
features:
* Standard SEO elements extracted by default (title, header tags, body text,
status code, reponse and request headers, etc.)
* CSS and XPath selectors: You probably have more specific needs in mind, so
you can easily pass any selectors to be extracted in addition to the
standard elements being extracted
* Custom settings: full access to Scrapy's settings, allowing you to better
control the crawling behavior (set custom headers, user agent, stop spider
after x pages, seconds, megabytes, save crawl logs, run jobs at intervals
where you can stop and resume your crawls, which is ideal for large crawls
or for continuous monitoring, and many more options)
* Following links: option to only crawl a set of specified pages or to follow
and discover all pages through links
* `robots.txt downloader <https://advertools.readthedocs.io/en/master/advertools.sitemaps.html#advertools.sitemaps.robotstxt_to_df>`_
A simple downloader of robots.txt files in a DataFrame format, so you can
keep track of changes across crawls if any, and check the rules, sitemaps,
etc.
* `XML Sitemaps downloader / parser <https://advertools.readthedocs.io/en/master/advertools.sitemaps.html>`_
An essential part of any SEO analysis is to check XML sitemaps. This is a
simple function with which you can download one or more sitemaps (by
providing the URL for a robots.txt file, a sitemap file, or a sitemap index
* `SERP importer and parser for Google & YouTube <https://advertools.readthedocs.io/en/master/advertools.serp.html>`_
Connect to Google's API and get the search data you want. Multiple search
parameters supported, all in one function call, and all results returned in a
DataFrame
* Tutorials and additional resources
* A visual tool built with the ``serp_goog`` function to get `SERP rankings on Google <https://www.dashboardom.com/google-serp>`_
* A tutorial on `analyzing SERPs on a large scale with Python <https://www.semrush.com/blog/analyzing-search-engine-results-pages/>`_ on SEMrush
* `SERP datasets on Kaggle <https://www.kaggle.com/eliasdabbas/datasets?search=engine>`_ for practicing on different industries and use cases
* `SERP notebooks on Kaggle <https://www.kaggle.com/eliasdabbas/notebooks?sortBy=voteCount&group=everyone&pageSize=20&userId=484496&tagIds=1220>`_
some examples on how you might tackle such data
* `Content Analysis with XML Sitemaps and Python <https://www.semrush.com/blog/content-analysis-xml-sitemaps-python/>`_
* XML dataset examples: `news sites <https://www.kaggle.com/eliasdabbas/news-sitemaps>`_, `Turkish news sites <https://www.kaggle.com/eliasdabbas/turk-haber-sitelerinin-site-haritalari>`_,
`Bloomberg news <https://www.kaggle.com/eliasdabbas/bloomberg-business-articles-urls>`_
Text & Content Analysis (for SEO & Social Media)
------------------------------------------------
URLs, page titles, tweets, video descriptions, comments, hashtags are some
exmaples of the types of text we deal with. ``advertools`` provides a few
options for text analysis
* `Word frequency <https://advertools.readthedocs.io/en/master/advertools.word_frequency.html>`_
Counting words in a text list is one of the most basic and important tasks in
text mining. What is also important is counting those words by taking in
consideration their relative weights in the dataset. ``word_frequency`` does
just that.
* `URL Analysis <https://advertools.readthedocs.io/en/master/advertools.urlytics.html>`_
We all have to handle many thousands of URLs in reports, crawls, social media
extracts, XML sitemaps and so on. ``url_to_df`` converts your URLs into
easily readable DataFrames.
* `Emoji <https://advertools.readthedocs.io/en/master/advertools.emoji.html>`_
Produced with one click, extremely expressive, highly diverse (3k+ emoji),
and very popular, it's important to capture what people are trying to communicate
with emoji. Extracting emoji, get their names, groups, and sub-groups is
possible. The full emoji database is also available for convenience, as well
as an ``emoji_search`` function in case you want some ideas for your next
social media or any kind of communication
* `extract_ functions <https://advertools.readthedocs.io/en/master/advertools.extract.html>`_
The text that we deal with contains many elements and entities that have
their own special meaning and usage. There is a group of convenience
functions to help in extracting and getting basic statistics about structured
entities in text; emoji, hashtags, mentions, currency, numbers, URLs, questions
and more. You can also provide a special regex for your own needs.
* `Stopwords <https://advertools.readthedocs.io/en/master/advertools.stopwords.html>`_
A list of stopwords in forty different languages to help in text analysis.
* Tutorial on DataCamp for creating the ``word_frequency`` function and
explaining the importance of the difference between `absolute and weighted word frequency <https://www.datacamp.com/community/tutorials/absolute-weighted-word-frequency>`_
* `Text Analysis for Online Marketers <https://www.semrush.com/blog/text-analysis-for-online-marketers/>`_

Social Media
------------
In addition to the text analysis techniques provided, you can also connect to
the Twitter and YouTube data APIs. The main benefits of using ``advertools``
for this:
* Handles pagination and request limits: typically every API has a limited
number of results that it returns. You have to handle pagination when you
need more than the limit per request, which you typically do. This is handled
by default
* DataFrame results: APIs send you back data in a formats that need to be
parsed and cleaned so you can more easily start your analysis. This is also
handled automatically
* Multiple requests: in YouTube's case you might want to request data for the
same query across several countries, languages, channels, etc. You can
specify them all in one request and get the product of all the requests in
one response
* Tutorials and additional resources
* A visual tool to `check what is trending on Twitter <https://www.dashboardom.com/trending-twitter>`_ for all available locations
* A `Twitter data analysis dashboard <https://www.dashboardom.com/twitterdash>`_ with many options
