Search engine optimization (SEO) software helps you improve a website’s online search visibility.
Search engine marketing (SEM) software allows you to automate and optimize your paid search advertisements.
Although the terms SEM and SEO are often used interchangeably, they actually have distinct meanings.
SEM is a category, which includes search engine optimization (SEO) as well as several other search marketing tactics, such as, pay per click (PPC) and social media marketing (SMM).
SEO, on the other hand, is a component of SEM that focuses exclusively on helping businesses rank higher in organic search results.
Software products in the SEM and SEO category usually feature the ability to automate keyword research and analysis, social signal tracking and backlink monitoring. Other key functionalities include the ability to generate custom reports and recommend actions for better performance. More advanced products often allow you to compare your search marketing performance with that of your competitors.
The right SEO and SEM tools help improve your brand visibility, drive more traffic to your websites, increase conversion rates and lower your overall spending on search marketing.

Choosing SEO and SEM software will largely depend on the features you plan to make use of. If you’re looking to improve your paid advertising, then an SEM software solution will be right for you. If you’re not interested in paid advertising, but want to improve your organic search results, an SEO software solution will be a good choice.
Small businesses usually look for a combo package which has a mix of different solutions. For instance, a startup without a dedicated SEO team may look for a smart combination of self-service tools, including a keyword research tool, a rank checking tool, and a website crawler.
Large enterprises generally look for an end-to-end solution that combines the best features of every solution. For instance, you may need a single product for checking daily rankings, creating customized reports, monitoring competitors and doing domain analysis, among other things.
Key features that all users should consider when deciding on a solution are as follows:
Improve your organic search engine visibility. When you use SEO software, you will be able to understand which keywords are easy best to rank for within your specific niche. You will be able to tailor your content towards those keywords and acquire backlinks from sites with high domain authority to increase your overall organic search visibility.
Gain greater insight into yours and your competitor’s current SEO efforts. SEO software will provide you with the intelligence needed to analyze both your own and your competitors entire SEO strategy. You can then use this intelligence to improve and refine your own efforts to rank higher than the competitors in your industry for the keywords of your choice.
Reduce overall paid advertising spend. SEM software solutions that help you optimize and refine your ads when used with SEO leads to a decrease in cost per click (CPC) and an increase in click-through rate.
Raises brand awareness. When used properly, SEM will get your ads in front of your target audience with content that is highly relevant to them, all for free until they click on your ad. The higher you rank in the search engines, the higher the number of people who visit your website.
