Of course the latest keyword posts come on Top in search engines just because they are newly posted and are fresh. Regularly updated content is a Gold for you . So I just wanted to know how to keep it fresh to hit the SERPS high ?
Hire freelancer writer. Depending from a niche but you can get good results even with 2-3$ per article price range. Make them write in seo friendly manner. And update your site regularly.
Well, innovate more into your subject and write down whatever you find new there! Human thinking ability is unlimited.
Updating your website with fresh content is not difficult if you have enough knowledge about the subject of your website. Note that its not needed that you update your website with tens of new articles. No. Only one quality and unique article per day can help you a lot. And if you can't write yourself, you should hire some one to write unique content for you.
It's not necessary to update existing pages (unless they need it). But be sure to keep adding new pages on a regular basis.
Keep researching on the latest topics of your expertise and subsequently update your site. The freshness will be there and also the SERPs will follow those fresh ones (only if the quality is maintained).
Totally agree, keep pumping fresh articles and also you can deep link to your older post (no just to the domain root)
Dear Friend, this is not difficult to update content , if you can not update daily than you can update at least with in a week, search best content writer who can provide you best quality of back links.
