My Take
Surfer SEO has a strong edge over WriterZen.
But Writerzen is suitable if you are on a budget and need an all-in-one tool you can use to write and optimize your content to rank on search engines.
Surfer’s SERP Analyzer is more advanced and analyzes 50+ top pages ranking on Google for a target keyword thereby providing more detailed insights on how to outrank your competitors.
This is not so with WriterZen which provides an overview for only 10 pages ranking for a target keyword. Surfer has a free keyword research tool that you can add as a chrome extension while WriterZen keyword research tool is tied to credits.
A specific number of credits is assigned to you depending on your plan. Each keyword research deducts one credit. When it comes to language, Surfer supports many major languages. WriterZen supports only English language.
Although WriterZen has an in-built writing assistant, it is basic compared to what Jasper AI which integrates with Surfer offers.
On top of that, WriterZen doesn’t have a stand-alone Content Planner, Content Editor, and Audit tools which are all available on Surfer.
Talking about collaboration, Surfer supports you to work with your team. Beyond sharing content via URL to your team members which WriterZen allows, you can invite up to 10 members of your team to collaborate with you on a project.
Below are some testimonials from Surfer users on the official Facebook group.

Features of Surfer SEO
Let’s dive into the features of Surfer for you to see what to expect from the tool.
1. Keyword Research Tool ( Keyword Surfer)
You can use it to check the search volume of your main keyword or also see other related keywords. This keyword research tool is available in 70 different languages and you can choose any location of your choice.

When you install the Chrome extension, it provides the following data for a target keyword directly from your browser:
- Monthly organic traffic of pages ranking on Google’s search results for a particular keyword
- Their word count
- Number of times their main keyword appeared in the content
When you scroll down, you will see an option to generate an outline using Surfer for the keyword you want to write about.
2. SERP Analyzer
This is the engine of Surfer SEO. It analyzes pages ranking on Google for a particular keyword and provides a detailed insight on what to do and avoid to get your on-page optimization right. Enter the keyword you want to analyze, set a location, choose a language and click run SERP Analyzer.
Surfer scans the over 50 pages ranking top for such keywords and provides insight which can be seen in the screenshot below.

First, you see a graph that tells you the word count your content should have to compete for positions 1-10. Also, Surfer lists and analyzes the 50 top pages that dominate the search result for that keyword.
You see the content score, backlink score, and option to exclude any of the pages in your analysis. There is also a shortcut to view the content outline, run an audit, paste HTML and take a screenshot for each of the pages.
Let’s explore Surfer’s SERP Analyzer more and check out other features that matter.
Common backlinks: These are links that all top-ranking pages acquired from the same website
Prominent words & phrases: They are phrases and words that Google thinks are relevant and can influence the ranking of such pages.
Questions: What users ask about a particular keyword
Popular phrases: Group of words that most users search before landing on most of the pages ranking for the target keyword
Common phrases: These are phrases are appear in all the pages ranking for a target keyword
Keywords: They are related keywords pages ranking for a target also rank for.
The idea is to know how and when to include each of the keywords or phrases the SERP analyzer provides in your content to optimize it for search engines.
3. Audit Tool
Use the audit tool to boost the ranking of your pages on search results. Enter your URL, keyword and click Run an Audit. Within seconds, Surfer collects data for that page, analyzes it against its competitors, and provides an insight into the performance of the page.
It shows you the content score for that page and compares it against the pages ranking on positions 1-10. Also, it shows missing backlinks which may affect the ranking of your page. Missing backlinks are websites linking to your competitors but not you.

So it’s up to you to work to acquire backlinks from such websites. Internal link structure is a ranking factor and the audit tool shows internal links on your page and that of your competitors. Here you check if they’re relevant to the page. The audit tool provides the following insights:
- NLPs in the content
- Load time
- Time to byte
- Partial & exact keyword
- Title & meta description length
- Page structure
- Word count
4. Content Planner
Content planner helps you build clusters. Ranking for competitive terms requires you to create and write topic clusters to support the main topic.

When you enter the focus topic you want to write for, the content planner creates the clusters you should write, publish, and inter-link to boost your chances of ranking for the head term.
5. Content Editor
You can use the content editor to plan your content before writing and also boost the on-page SEO of a page you have published already.
Enter the keyword you want to write and Surfer will analyze the top-ranking pages and return a structure your content should follow and that includes:
- Number of images
- Word count
- Number of paragraphs
- The number of headings your content should have

The content editor has advanced options which you can use to enable the NLP, customize your content structure, and narrow it down to fit your needs.
For example, you can exclude social media pages like Facebook, Instagram, Twitter to ensure that your content structure captures only what your main competitors have done.
There are suggested terms that influence the ranking of your competitors’ pages and therefore should be in your content.
How does Surfer arrive at the suggested words and phrases that should be part of your content?
It uses NLPs to verify terms that influence ranking, its algorithm, and core keywords in your competitors’ pages.
