Best 8 Simple Steps to Complete a Technical SEO Audit

A technical SEO audit helps teams understand behind-the-scenes issues that affect search engine rankings like site speed, indexing, and backlinks. It’s important that SEO specialists have a full view of all of the elements that affect page rankings so that teams can take the best course of action to improve their positions.

Conducting daily technical SEO audits is crucial for building a great SEO strategy. But if you’re still starting out, beginning work with a new firm, or want to learn how to complete a technical SEO audit, it can be overwhelming.

In this article, we’ll go over eight steps to help you complete a technical SEO audit, increase web traffic to your web pages, and build your confidence as an SEO specialist.

What Is a Technical SEO Audit?

What most people think of as SEO is what specialists refer to as on-page SEO. This is where a professional optimizes the content that appears on a website so that it appears to the right audiences organically.

Technical SEO is not about the content that appears on a website but how users and search bots navigate through each page. A technical SEO audit is when specialists use a checklist of behind-the-scenes technical elements to review and improve to increase page rankings in search engines.

What’s involved in a technical SEO audit

When SEO specialists perform a technical SEO audit, they check a series of factors that impact a website’s speed, performance, and usability, and they take action towards optimizing web pages. Regular, sometimes daily technical SEO audits can help specialists learn about technical issues they might not know about.

SEO specialists and marketing teams use tools such as Google Search Console, Google PageSpeed Insights, web crawlers, mobile crawlers, and indexing tools, to optimize their web pages and improve search engine rankings through technical SEO audits.

When you should complete a technical SEO audit

It’s important to complete technical SEO audits regularly. Some businesses use technical SEO to help improve cash flow via web traffic and conversions, so daily audits are a must. But for blogs and personal websites, weekly or monthly SEO audits should suffice.

Besides regular maintenance, you should always complete a technical SEO audit when moving to a new site, start freelancing for a new client, or when you first get hired at a firm. And of course, technical SEO audits also come in handy during periods where your rankings are stagnant or in decline.

What you need to do before conducting a technical SEO audit

Before you conduct a technical SEO audit, there are a few things you need to do:

  1. Find out what your client’s goals are. Do they want to improve SEO, make web pages easier for users to navigate, or optimize their site’s performance?
  2. Get access to their tools and analytics. To perform a technical SEO audit, you’ll need to be able to access things like the site’s Google console, performance monitoring analytics, and anything else you need to meet your client’s expectations.
  3. Sign a written agreement. Whether you’re contracted for one job or ongoing work, it’s important to have a written agreement explaining what you’re going to do and how you’ll do it. You’ll also need liability disclaimers and a list of responsibilities so that you aren’t held accountable for things outside your control.

Having all of this information beforehand is important so you can prepare for the work. For example, if you were working for a SaaS company, you might be hired to perform a technical SEO audit on certain specialized landing pages based on their industry and business type so that they appear in front of the right people according to their previous searches and user behavior.

But if you were working for a retail company, your job might be to ensure that pages load fast, that there are no image issues, and that all of your 4xx links redirect to the correct locations.

A Step-by-step Guide to Completing a Technical SEO Audit

Let’s go through each of the eight steps that will help you complete a technical SEO audit successfully.

1. Crawl your website

Use a tool that scans your website to check how many URLs there are, how many are indexable, and how many have issues, including any problems hindering your site’s performance.

For Wix users, Deepcrawl is the top tool that professionals trust, but most people start out using Google Search Console:

  1. Decide which sitemap format you want to use: XML, RSS, mRSS, Atom 1.0, or Text.
  2. Create the sitemap either manually or automatically with a sitemap generator.
  3. Add your sitemap to your robots.txt file, or submit it to Google through the Search Console.

2. Spot indexing issues

If the website has pages that Google can’t crawl, it may not be indexed properly. Here are some common indexing issues to look for:

  • indexation errors
  • robots.txt errors
  • sitemap issues

The easiest way to check your site indexation is to use the Coverage Report in Google Search Console. It will tell you which pages are indexed and why others are excluded so you can fix them. You may need to optimize your crawl budget to ensure that your pages are indexed regularly.

3. Check technical on-page elements

Although on-page elements are often left out of a technical SEO audit, attending to them is considered basic housekeeping that needs to be addressed. Here’s a list of on-page elements to review during a technical SEO audit:

  • page titles and title tags
  • meta descriptions
  • canonical tags
  • hreflang tags
  • schema markup

4. Identify image problems

Image optimization is another often-overlooked aspect that’s crucial to technical SEO audits. Ensuring images have no errors can help a site’s ranking in many ways, including improved loading speeds, increasing traffic from Google Images, and improved accessibility.

Be sure to identify technical image problems such as:

  • broken images
  • image file size too large
  • HTTPS page links to HTTP image
  • missing alt text

5. Analyze internal links

Next, it’s important to analyze internal links. Identify 4xx status codes that need to be redirected. If there are any orphan pages with no internal links leading to them, identify and address them.

6. Check external links

Next, move on to the external links. External links are important because they make a website more credible to users and search engines. Ensure all backlinks are active and don’t lead to broken pages, and check to see that all pages have outgoing links.

7. Measure site speed and performance

Google Search gives better ranking positions to websites with good performance and fast loading times.

Here’s how to use Google PageSpeed Insights to check on a site’s performance:

  • Go to the Google PageSpeed Insights page.
  • Input your web page URL into the box.
  • Click analyze and view your results.

This tool will provide you with an overall score, field data, suggestions, and other diagnostic information that can help improve your page speed.

8. Ensure your site is mobile-friendly

Finally, ensure that the site you’re auditing is mobile-friendly, responsive, and compatible with different browsers. Google favors responsive web pages that load easily and are easy to view regardless of the user’s device.

Here’s an example of how CryptoWallet.com uses mobile and web-friendly design:

CryptoWallet web view

Web view

CryptoWallet mobile view

Mobile scrolling view

It’s easy to check the responsiveness of a website with a tool like Responsive Web Design Checker or with these steps in Google Chrome:

  • Open the web page in Google Chrome.
  • Right-click to open the menu and select Inspect.
  • Click on the Toggle device toolbar to see how the website looks on screen and mobile.

Wrapping Up

Technical SEO audits help optimize websites so that they’re easier for users and for indexing bots to understand. Conducting a technical SEO audit involves a lot of elements, but this eight-step process can help streamline your workflow so that you don’t miss a thing.

Matplotlib Cheat Sheet: Plotting in Python

This Matplotlib cheat sheet introduces you to the basics that you need to plot your data with Python and includes code samples.

Data visualization and storytelling with your data are essential skills that every data scientist needs to communicate insights gained from analyses effectively to any audience out there. 

For most beginners, the first package that they use to get in touch with data visualization and storytelling is, naturally, Matplotlib: it is a Python 2D plotting library that enables users to make publication-quality figures. But, what might be even more convincing is the fact that other packages, such as Pandas, intend to build more plotting integration with Matplotlib as time goes on.

However, what might slow down beginners is the fact that this package is pretty extensive. There is so much that you can do with it and it might be hard to still keep a structure when you're learning how to work with Matplotlib.   

DataCamp has created a Matplotlib cheat sheet for those who might already know how to use the package to their advantage to make beautiful plots in Python, but that still want to keep a one-page reference handy. Of course, for those who don't know how to work with Matplotlib, this might be the extra push be convinced and to finally get started with data visualization in Python. 

You'll see that this cheat sheet presents you with the six basic steps that you can go through to make beautiful plots. 

Check out the infographic by clicking on the button below:

Python Matplotlib cheat sheet

With this handy reference, you'll familiarize yourself in no time with the basics of Matplotlib: you'll learn how you can prepare your data, create a new plot, use some basic plotting routines to your advantage, add customizations to your plots, and save, show and close the plots that you make.

What might have looked difficult before will definitely be more clear once you start using this cheat sheet! Use it in combination with the Matplotlib Gallery, the documentation.

Matplotlib 

Matplotlib is a Python 2D plotting library which produces publication-quality figures in a variety of hardcopy formats and interactive environments across platforms.

Prepare the Data 

1D Data 

>>> import numpy as np
>>> x = np.linspace(0, 10, 100)
>>> y = np.cos(x)
>>> z = np.sin(x)

2D Data or Images 

>>> data = 2 * np.random.random((10, 10))
>>> data2 = 3 * np.random.random((10, 10))
>>> Y, X = np.mgrid[-3:3:100j, -3:3:100j]
>>> U = 1 X** 2 + Y
>>> V = 1 + X Y**2
>>> from matplotlib.cbook import get_sample_data
>>> img = np.load(get_sample_data('axes_grid/bivariate_normal.npy'))

Create Plot

>>> import matplotlib.pyplot as plt

Figure 

>>> fig = plt.figure()
>>> fig2 = plt.figure(figsize=plt.figaspect(2.0))

Axes 

>>> fig.add_axes()
>>> ax1 = fig.add_subplot(221) #row-col-num
>>> ax3 = fig.add_subplot(212)
>>> fig3, axes = plt.subplots(nrows=2,ncols=2)
>>> fig4, axes2 = plt.subplots(ncols=3)

Save Plot 

>>> plt.savefig('foo.png') #Save figures
>>> plt.savefig('foo.png',  transparent=True) #Save transparent figures

Show Plot

>>> plt.show()

Plotting Routines 

1D Data 

>>> fig, ax = plt.subplots()
>>> lines = ax.plot(x,y) #Draw points with lines or markers connecting them
>>> ax.scatter(x,y) #Draw unconnected points, scaled or colored
>>> axes[0,0].bar([1,2,3],[3,4,5]) #Plot vertical rectangles (constant width)
>>> axes[1,0].barh([0.5,1,2.5],[0,1,2]) #Plot horiontal rectangles (constant height)
>>> axes[1,1].axhline(0.45) #Draw a horizontal line across axes
>>> axes[0,1].axvline(0.65) #Draw a vertical line across axes
>>> ax.fill(x,y,color='blue') #Draw filled polygons
>>> ax.fill_between(x,y,color='yellow') #Fill between y values and 0

2D Data 

>>> fig, ax = plt.subplots()
>>> im = ax.imshow(img, #Colormapped or RGB arrays
      cmap= 'gist_earth', 
      interpolation= 'nearest',
      vmin=-2,
      vmax=2)
>>> axes2[0].pcolor(data2) #Pseudocolor plot of 2D array
>>> axes2[0].pcolormesh(data) #Pseudocolor plot of 2D array
>>> CS = plt.contour(Y,X,U) #Plot contours
>>> axes2[2].contourf(data1) #Plot filled contours
>>> axes2[2]= ax.clabel(CS) #Label a contour plot

Vector Fields 

>>> axes[0,1].arrow(0,0,0.5,0.5) #Add an arrow to the axes
>>> axes[1,1].quiver(y,z) #Plot a 2D field of arrows
>>> axes[0,1].streamplot(X,Y,U,V) #Plot a 2D field of arrows

Data Distributions 

>>> ax1.hist(y) #Plot a histogram
>>> ax3.boxplot(y) #Make a box and whisker plot
>>> ax3.violinplot(z)  #Make a violin plot

Plot Anatomy & Workflow 

Plot Anatomy 

 y-axis      

                           x-axis 

Workflow 

The basic steps to creating plots with matplotlib are:

1 Prepare Data
2 Create Plot
3 Plot
4 Customized Plot
5 Save Plot
6 Show Plot

>>> import matplotlib.pyplot as plt
>>> x = [1,2,3,4]  #Step 1
>>> y = [10,20,25,30] 
>>> fig = plt.figure() #Step 2
>>> ax = fig.add_subplot(111) #Step 3
>>> ax.plot(x, y, color= 'lightblue', linewidth=3)  #Step 3, 4
>>> ax.scatter([2,4,6],
          [5,15,25],
          color= 'darkgreen',
          marker= '^' )
>>> ax.set_xlim(1, 6.5)
>>> plt.savefig('foo.png' ) #Step 5
>>> plt.show() #Step 6

Close and Clear 

>>> plt.cla()  #Clear an axis
>>> plt.clf(). #Clear the entire figure
>>> plt.close(). #Close a window

Plotting Customize Plot 

Colors, Color Bars & Color Maps 

>>> plt.plot(x, x, x, x**2, x, x** 3)
>>> ax.plot(x, y, alpha = 0.4)
>>> ax.plot(x, y, c= 'k')
>>> fig.colorbar(im, orientation= 'horizontal')
>>> im = ax.imshow(img,
            cmap= 'seismic' )

Markers 

>>> fig, ax = plt.subplots()
>>> ax.scatter(x,y,marker= ".")
>>> ax.plot(x,y,marker= "o")

Linestyles 

>>> plt.plot(x,y,linewidth=4.0)
>>> plt.plot(x,y,ls= 'solid') 
>>> plt.plot(x,y,ls= '--') 
>>> plt.plot(x,y,'--' ,x**2,y**2,'-.' ) 
>>> plt.setp(lines,color= 'r',linewidth=4.0)

Text & Annotations 

>>> ax.text(1,
           -2.1, 
           'Example Graph', 
            style= 'italic' )
>>> ax.annotate("Sine",

             right=0.9,
             top=0.9,
             bottom=0.1)
>>> fig.tight_layout() #Fit subplot(s) in to the figure area

Axis Spines 

>>> ax1.spines[ 'top'].set_visible(False) #Make the top axis line for a plot invisible
>>> ax1.spines['bottom' ].set_position(( 'outward',10))  #Move the bottom axis line outward
