“Blogging” – SEMrush overview report for keyword

Features: There are a lot of features in SEMrush search engine marketing tool. I recommend you to read the review of SEMrush to learn more about SEMrush and How it can help to grow your blog.

  • Ability to do local keyword research: Local SEO is very popular these days as offline marketers started using Internet to acquire new customers. Finding keywords which your target audience use on is very easy with SEMrush. In fact, many offline marketers use local search to acquiring new customers.
  • Live Updates: One of my favorite features in SEMrsuh search engine marketing tool is live updates. SEMrush-bot crawl the web in every day to get fresh data. So you always get new information about your quest.

  • Tracking Keyword positions: This is my favorite feature in SEMrush Keyword research tool. By using keyword tracking tool, you can track your web pages’ SERP positions for each keywords in every day. Since Google SERP is very complicated and it’s very hard to retain an absolute keyword position, it is better to track your money keywords.

Besides these features, you can also find best converting, traffic driving and easy to rank keywords using SEMrush. I always use SEMrush keyword research tool to find untapped keywords which my competitors already are using.

Limits and Disadvantages: You have to upgrade in order to get more features such as Historical data.

Prices: SEMrush starts with Pro subscription, which is worth  $69.95/month. SEMrush Pro account receives 10,000 results per report, 3,000 reports per day and Tracking (5 campaigns, 500 keywords).

But if you want more in-depth analysis, such as historical data (very useful to find people’s buyer intents and keyword trends), branded PDF reports and more reports, you need to subscribe to a SEMrush Guru account. SEMrush Guru package charges from you $149.95 per month. But it’s worth it subscribes to a SEMrush Guru account, as you can find more untapped keywords.

I recommend you to use SEMrush as part of your SEO and content marketing campaign, not just only because it has powerful tools to analyze keywords, because it saves your time & efforts and gives you more convenience to find untapped keywords.
