The proxy market is constantly expanding and lots of new names are coming to the market. That means that proxies, as a product, are pretty useful and popular among businesses and individuals. There are two main types of proxies - residential proxies and datacenter proxies, with residential IPs being widely used for such purposes as web scraping, market research, online privacy, working with automatic bots, etc.
With that being said, this article will overview how to easily get residential proxies and which 3 providers can offer you the best services in 2020.

SMARTPROXY

Smartproxy doesn’t price per proxy, so you can access the whole pool with unlimited connections and put your scrapers into max gear if you’re looking for reliable residential proxies to scrape websites. Smartproxy now offers 40 million IPs proxy pool so it’s more than enough knowing the fact that you can access the whole pool. Their residential proxies are also fast and aren’t flagged so you can use them for SEO matters, working with social marketing on all major social networks, copping sneakers, testing affiliate programs, etc. Here are some specifics of Smartproxy residential proxies:
-Unlimited connection
-40M+ IPs from 195+ locations
-Up to 10min. sticky sessions
-HTTP(s) proxies
-Easy to use Dashboard
-Proxy address Generator
-Chrome proxy extension

Smartproxy is also one of the cheapest proxy provider in the market with the starting price of $75 for a monthly plan. Besides, you can also get a discount for all the pricing plans with the code SMARTPRO. With everything that Smartproxy is offering for its customers, it would be a smart choice to get residential proxies from them.

SHIFTER

Shifter (also known as Microleaves) is a residential proxy network that consists of over 31 million IPs around the world (at least this is what they claim). Their network rotates between IP addresses and ports your connection every 5 minutes. They don’t provide a clear number of how many countries they support. Their website simply suggests that they cover every city in the world so let’s assume this is true. What is interesting about this proxy provider is that they are offering you backconnect proxies. These proxies are a special kind of proxy that connects to our entire proxy pool and gets assigned a new residential IP address every rotation time, depending on your settings.
When it comes to purchasing proxies from Shifter, it gets a little tricky - the reason for that is that Shifter sells a number of proxy ports, you choose according to your need. But you also have to choose between Basic Backconnect proxies and Special Backconnect proxies. According to them, it’s a huge difference between what your proxies will be capable of. That is also seen in the price range - for 25 Basic proxies, you will pay $250 monthly. For Special proxies - 25 ports will cost you $500 per month. Shifter isn’t a cheap proxy provider and sometimes buying a number of ports instead of purchasing traffic isn’t the wise move. Nevertheless, Shifter can offer you great services and fast proxies that can be used for social media, scraping, sales intelligence, etc. You can read more about them here.

PACKETSTREAM

PacketStream is a new addition to the proxy market. Started sometime in 2018, this American provider is still in toddler shoes. But despite being of young age in a proxy market, this provider definitely can offer some amazing proxy services and that’s what matters the most.
I would also like to mention that PacketStream isn’t merely a service – it’s a marketplace. And here’s the interesting part - on the provider’s website, you can not only buy proxies but also sell your own traffic; in other words, your device effectively becomes a proxy itself.
This straightforward business model has allowed PacketStream to collect an impressive number of residential IPs in short notice. It’s also dumped the prices to impressive lows – with no entry threshold.
Some of the PacketStream features:
-Low price
-Good performance
-HTTP(S)
-Country targeting

At the moment, PacketStream offers around 7 million residential proxies. The number is very fluid, as it depends on people who participate in the provider’s bandwidth-selling program. As for the price, you can pay $50 per month for their cheapest plan that includes 50 GB traffic so it could be worthed for those who want to try proxies for the sake of knowing how to work with them and use them with various automatic bots.

...it’s not so difficult to get residential proxies - the market has plenty to offer, you only need to know what you’re looking for and how you will use these services. Apart from these 3 providers that I’ve mentioned in the article, you can also check Proxy Market research 2020 for more various alternatives that also could suit your needs.

Tips on how to avoid the main obstacles while web scraping

Web scraping has become a very important service in today’s business world and can benefit you in many various ways. Data science helps improve your business, take a better look into the situation of the market, let you get better ideas about your business prospects and find new ways on how to reach your target audience and increase brand awareness.
But web scraping isn’t an easy task and even the professionals usually meet with various obstacles that slacken their work or even make it almost impossible to execute. This article is about some of these obstacles that web scrapers usually meet in their way and tips on how to avoid them.

Top 5 obstacles while web scraping:

Captchas.
You definitely saw many of these while you were trying to access the content you wanted and it was asked to you to prove that you aren’t a robot. It can really bother you sometimes but mostly you deal with it pretty easily. But it’s definitely an issue when you have to scrape a website and these CAPTCHAS are stopping you.
Many CAPTCHA solvers can be implemented into bots to ensure non-stopping scrapes. Although the technologies to overcome CAPTCHA can help acquire continuous data feeds, they could still slow down the scraping process a bit. There are some other ways to avoid CAPTCHA so you should always check them out.

IP blocks.
Web scraping is an automatic action that can be easily detected by the website. IP blocking is a real issue in many scraping cases. IP blocking typically happens when a server detects an unnaturally high number of requests from the same IP address or if the web scraping tool makes multiple parallel requests. This usually ends in you being banned from the website without the possibility to gather data you want.
Nevertheless, this can be solved by simply using proxy services. Proxies mask your own IP address (for privacy matters) and help imitate natural human activity on the website so you are safe using your scraping tool to gather data you need without being blocked.

Geo-restrictions.
Many websites limit access to some geographic regions. They detect locations by checking the IP addresses of every device that tries to connect to their servers. People use proxy servers to hide their IP address and change it to the proxy server’s IP. This means that anyone using a high quality US proxy (or any other, depending on the country/region you have to access) can access any US-only content without restrictions.

Real-time data scraping.
Real-time data scraping is essential when it comes to price comparison, inventory tracking, etc. With so much data online the data can change very quickly and may lead to some great issues for business. This is why the scraper needs to monitor the websites all the time and scrape data constantly. Even so, it still has some delay as the requesting and data delivery take time.
In some cases, this is a pretty big obstacle and it’s not easy to solve it. So if you’re scraping data that has the potential to change quickly and more than several times a day, you have to invest in a reliable web scraping tool that would have the capacity to deal with such issues. The market can offer some great real-time crawlers/scrapers that can be used, so it is worth investing in them.

The need to log in.
Some protected information may require you to log in first. When you’re using an automatic tool for scraping, the need to log in to the website definitely stops your performance for quite some time. These logins are important because of the cookies that are installed at the moment you log in to the website so the website would know you’re the same person who just logged in earlier. When scraping websites requiring a login, be sure that cookies have been sent with the requests.
Some web scraping tools have features that help with this login policy and thus help you to avoid unnecessary issues, so once again there is great importance in your choice of the tool you will be using. Right tools always help you to perform better when scraping and help bypass many obstacles in your way.

In reality, web scraping alone is as good as you’re capable of solving the problems that come in your way. When dealing with the most common problems the most common solutions would be always using proxy services and to be smart about the tool you choose to use. I would highly recommend using proxy services that could provide you a big pool of IPs from various locations and since this is crucial in many cases. Here are some of the recommendations you can check:
Smartproxy — fast and reliable services. This provider can offer you more than 10 million IPs from more than 195 locations and really great pricing plans according to your needs. Besides, with the coupon SMARTPRO you can get a 20% discount for your first purchase so it’s worth to check;
