How Top SEO Companies Optimize Their Websites

How Top SEO Companies Optimize Their Websites

In the previous study, we created infographics based on static metrics and for websites from all niches. In this study, we decided to research a specific niche in dynamics. We looked for an answer how top websites of the niche are optimized and how many changes they made for a month.

So, we decided to start with an SEO niche. Research contains websites of SEO blogs, SEO tools, and SEO agencies. Why we choose this niche? It is interesting to know how websites that teach SEO or do SEO for others work with their own websites.

Research methodology

We chose top 100 websites that ranked by keywords like seo blog, seo tips, seo agency in the USA according to Ahrefs data and started monitoring them in Sitechecker.

However, we didn’t include some brands (Moz, Semrush, Woorank, Seobility, Seositecheckup) that have websites with much more pages than average. We also exclude our website from the sample.

Yes, there are many great SEO blogs that write perfect guides, announcements, and forecasts, but they don’t rank by keywords mentioned above and they weren’t included into the sample. However, this is not our last study. I hope in the future we will make research on top SEO websites based on 1000 websites, not 100.

So, our Site Monitoring tracked changes on chosen top 100 SEO websites from August, 1 to August, 30 daily. Now we know how many changes in meta tags and content these websites made and how their Website Score is changed in 1 month. You can view the raw data in this Google Sheet. Based on this table we built all graphs.

Changing in Title and H1 tags

Nathan Gotch changed a Title tag on the academy page. I guess he found data in Google Search Console that many people are interested in the start date of the new course. So he decided to change the Title for increasing CTR in SERP.

Conclusion

The changes highlighted above are a small part of all changes website owners made. Only 9 from 100 websites didn’t make any changes during the month. The research leads to the following conclusions:

  1. Old websites keep growing but, young websites make more changes. They have to move faster to become the first 🙂
  2. Most of the best websites by domain age, traffic, linked domains have good or perfect Website Score.
  3. Website owners actively work on their websites but do not notice mistakes they make during SEO work.
