The blog on heysho.com is a platform to output daily learnings and practice SEO strategies.
Articles on digital marketing, SEO, and digital tools are posted about 1 to 4 times a month, aiming to improve search rankings and increase traffic by optimizing each article for SEO.
While working as an SEO manager for a company, I realized the importance of speeding up the team's trial and error process.
During this time, my desire to manage and experiment with my own site grew stronger, leading me to start the blog.
In 2020, using the topic cluster method (which was not yet widely recognized), I posted articles about digital tools like Microsoft Teams and Notion, achieving top search rankings for major keywords.
As a result, monthly page views reached up to around 170,000 at times.
Here are the keywords that I ranked for with the site:
Running the blog as a personal project while being a full-time employee presented several challenges.
From late 2020, Google's algorithm changes favored corporate sites, making it difficult to gain traffic for individual's personal sites.
From late 2020, my main job became busier, reducing the opportunities to post articles.
Posting articles on topics like digital marketing and SEO faced tough competition from well-resourced and authoritative sites like Hubspot, making it difficult to compete.
Due to reduced blog postings, the site was renewed as a portfolio site in March 2024.
The blog posting feature remains, and articles are posted every 2 to 3 months as a technical memo.
