Anyone engaged in SEO can't do without dealing with search engines. Checking website rankings, competition landscape research, backlink analysis –nearly every SEO task requires intensive use of SEs. And only up-to-date laser-precise data can lay the base for a killer SEO strategy that when implemented lets your website break into Google's top listing.

Needless to say that manual collecting of search engine data is an ineffective time-hog. So if you are serious about website promotion you need to get top-class SEO tools that will effectively shoulder all routine SEO job and save your precious time.

But an ideal SEO tool must not only perfectly handle website optimization tasks, but also stay on friendly terms with search engines. The point is that any SEO software makes search engines frown as it overloads their servers sending automated queries. So search engines may temporary block access to their data sources, which stops your software's search for a couple of hours.

So-so SEO tools can't handle that and you have to wait to get back to work. But the leading SEO software developers have spared you the inconvenience even of such a short pause. The top SEO tools are fitted with the most advanced safety features that save you needless worries and make the process of collecting data smooth and safe.

Here is the list of features that let you stay safe and sound when picking up data from search engine:

-Human Emulation-

This feature makes SEO software queries look "natural", so you act like a human being in search engines eyes. The software uses the real browser to surf webpages like a real user, visits search engines' home pages before sending next-in-turn query, makes random delays between searches etc. Perhaps the only disadvantage of this method is that it takes a little longer to complete the tasks.

• Proxy Rotation-

Switching between proxies lets you cover the tracks when obtaining search engine data. Using Proxy Rotation safety feature you will be able to get the data you need quick and undetected. But using this feature you must keep in mind that free proxies get unresponsive or die very quickly. So it's better to purchase exclusive paid proxies so you could run your tasks and stay home and dry.

• Search Engines API Keys-

Using API keys officially allows you running your searches and getting the data you need. But if you use API keys that puts limits on the volumes of data you get. For instance the maximum number of queries you are officially allowed to make using Yahoo! API key is 5,000 a day.

• User Agents Rotation-

That feature lets you appear to search engines under different masks. An SEO tool can "dress up" in various user agents making search engines assume that each search request comes from a different user so you can safely access search engines databases.

Some leading SEO software providers like IBP, Web CEO, Market Samurai have also equipped their tools with these search engine safety mechanisms. So if you get top-notch SEO software you can optimize an unlimited number of websites, run ranking and backlink checks safely, without fear to violate search engines' policies.

• Anti-CAPTCHA-

And the last but not least on the list of search safety features is a brand-new Anti-CAPTCHA feature. The leading SEO software provider Link-Assistant.Com has cooperated with one of the best CAPTCHA recognition services to bring its users a completely CAPTCHA-free working environment and slash their workload big time. When running their searches users don't need to stir a finger whenever a CAPTCHA pops up. All CAPTCHAs get manually filled out by lightning-fast CAPTCHA entry service with no action on the user's part. That ensures getting the correct data and absolute freedom when collecting search engines data.
