ISOWQ – International Studies of Website Quality

International Studies of Website Quality (ISOWQ) is an international research project created by Interface Poland in 2011. Its main purpose is to examine and present detailed data related to the technical quality of websites available on the global network.

Positioning in Google

Google's unwavering position in Poland determines that we focus on positioning in this search engine - the most popular and most trusted by Internet users. High positions in the Google website ranking also translate into the prestige of a company that gains a lot in terms of image.

SEO Marketing

The benefits of organic positioning:
  • opportunity to compete with largest companies in the industry
  • acquiring new clients
  • attracting users interested in specific products and services
  • local and national reach of advertising
  • adjusting costs to individual needs
  • image benefits
  • long lasting effects
Local positioning

Companies operating on the local market, such as car workshops, restaurants, hairdressing salons, fitness clubs, etc. can truly enjoy the so-called local positioning.

The impact of geolocation on search results is undeniable. Google knows our location and for some queries such as "Italian restaurant" or "beautician" can present adequate results even if they lack location.

Local queries are usually highly effective, i.e. there is a very high probability that a web surfer looking for a restaurant or photocopier in a particular area will quickly use the search engine prompts.

Google Ads

Advanced Google Ads campaigns allow you to quickly reach internet users interested in specific products or services. It is an ideal solution if you care about immediate effects, have a seasonal offer or are just starting your business and want to attract the first customers.

Logo Google Ads

Advantages of Google Ads:
  • precise ad targeting
  • free ad display, payment is only made for clicking the ad and going to the website
  • wide reach and easy access, opportunity to launch campaigns in selected countries within 24h
  • full control over the campaign during its duration, regarding broadcast time (time of day, days of the week), location, etc.
  • reports from the campaign enabling its current modification - changing keywords, budget and other parameters
  • ability to control expenses and optimise your budget
  • quick presence, under keywords that are considered extremely difficult in the process of organic positioning
  • no restrictions on the number of keywords included in the campaign
  • performance evaluation - easy to measure return on investment

The Google Ads advertising system is a tool widely used in the promotion of websites on the Internet; which works very well seasonally. In order to achieve a stable and long-term presence in search results, I recommend organic positioning.

Sharp MZ-800 with Z80 processor and assembly language programming

A great era of 8-bit computers

My first computer, Sharp MZ-800, was based on a Zilog three-and-a-half-hectare Z80A processor and had only 64 KB (yes, kilobytes) of RAM. To this day, I remember those emotions when the expansion of VRAM by another 16 KB caused the colour palette to be expanded from 4 to as many as 16. The computer provided a machine code editor as standard, and games and application programs were uploaded from tape cassette. The parameters of the above-mentioned Sharp MZ-800 computer in comparison with the capabilities of the Omega2 minicomputer are not too good, because it was almost 165 times slower and had more than 2000 times less RAM. But in those days memory was calculated in kilobytes, and transmission in baud rate (not to be confused with bits per second).

Here you can find more information about the Sharp MZ-800:
