1. Excessive repetition of keywords (Keyword Stuffing)
In years past, repeating a certain word in the text could increase the site's rank, but with new Google algorithms (such as BERT and RankBrain), it has exactly the opposite effect. Google is looking for the concept and "user intent" (Search Intent), not parroting words.
- Negative effect: Google will identify your site as spam and reduce your ranking in search results.
- Solution: Use LSI keywords (related and synonymous words). Text should be written for humans, not robots. Follow the rule of 3% keyword density.
2. Slow loading speed (Core Web Vitals)
Site speed is one of the vital ranking factors that Google examines in the form of "Core Web Vitals". If the user waits for more than 3 seconds for the site to open, he will most likely close it (high bounce rate).
- Negative effect: Google considers a high bounce rate as a sign of poor site quality and lowers your ranking.
- Solution: Use new image formats such as WebP, minify CSS and JS codes, and use caching and CDN systems.
3. Not optimized for mobile
Google has adopted the "Mobile-First Indexing" policy for years; This means that the mobile version of your site is the original version and Google's ranking criterion. If your site is difficult to read on mobile or its buttons cannot be clicked with a finger, you have lost the chance to get a ranking.
- Negative effect: Gradual removal from mobile search results, which includes more than 80% of web traffic.
- Solution: Use responsive design. Texts should be readable on mobile without zooming.
4. Ignoring the attractiveness of meta tags (low CTR)
Even if you are on the first page of Google, if the "Title" and "Meta Description" are not attractive, no one will click on your site. Google uses the click rate (CTR) to measure the quality of the site.
5. Poor internal linking structure
Internal linking is the backbone of your site. If your important articles or products are not connected, Google bots cannot find the deep pages of the site and credit (Link Juice) on your site will not be distributed properly.
- Negative effect: Important pages of your site are not indexed and their value remains low with Google.
- Solution: Always link to at least 3 other related pages on your site in each article. Links should have descriptive and related anchor texts.
Frequently asked questions (FAQ)
1. Is using long-tail keywords better than short keywords?
Yes; Long keywords usually have less competition and "searcher intent" is more precisely defined in them; Therefore, they will bring a higher conversion rate for your site.
2. How do I know if my site is optimized for mobile?
Just use the official Google tool called Mobile-Friendly Test. This tool tells you how your site looks on mobile from Google's point of view.
3. Does excessive internal linking incur a penalty?
If the links are natural and in line with the user's needs, no. But if you link too many unrelated pages in each paragraph, Google may consider it as spam. Observe the balance.
4. What is the effect of site speed on sales?
Research has shown that for every 1 second of delay in site loading, your conversion rate and sales can decrease by up to 7%. Speed is directly related to the profitability of your business.
