1. Your website looking so old.

   -Your web pages must be easy to read and always up to date. Consider using modern and appealing designs with user friendly navigation controls. This helps users gain easy access to the information they need.

2. Cluttered pages and content.

   -Make sure that your website has a clear objective. Having multiple pages with slightly changed content will only trigger Google’s algorithm and might suffer penalties. Your content must always target what is valuable to your readers.

3. Having irrelevant links and images.

   –  Use online tools for checking backlinks and images. This helps make sure that your website does not contain broken links that drive visitors and linkers away.

4. Slow page loading speed.

   – Time matters to everyone. Readers can get impatient if your website takes forever to load. Pages that load slowly will drive readers away and will go to another page. In addition, page speed is an important factor in SEO. Make sure that all pages of your website load quickly.

5. Content is not current.

   – If your website has a blog, make sure to post content frequently. If you cannot maintain a blog, it can do more harm than good. People don’t want to link to abandoned websites.

6. Too many ads in one page.

   – Having too many ads appearing in one page (specifically in the home page)is not good for SEO. People do not want to link to ads. They want to link to websites with valuable and optimized content.

7. Duplicate content.

   – Duplicate content is a clear violation of the Google webmaster tools’ guideline. Therefore, your blog or website must always contain fresh and unique content because this is what site visitors are looking for.
