This research is going to compare internet results derived by some users Technical and engineer groups, factual sciences and economics in G.G.O with restriction at title & URL, and also the of keyword's appearance in the internet URL and research group's titles. Survey society are 90 experts of Hamedan G.G.O They searched their desired keywords (one or more words) in the URL and title of web pages and determined the amount of relevance retrieval results in the check list that was provided for this reason. For classifying and data analysis, descriptive statistics (frequency, mean, base of sample and standard deviation) and inferential statistics (univariateKalmvgvrf Smirnov test, Duncan’s post hoc test, chi-square independence test, paired t-test, correlation COEFFICIENT erson and Spearman’s test, ANOVA and chi Krvksa L – Wallis test) used. The results showed that the increase in the number of search keywords and URLs as the correlation decreases and the greater the degree of correspondence between the title and the URL link is higher. the result show up that with increase of search keywords scale in the title & URL will reduce and there are meaningful defference between numbers of present thematic keywords at title & URL researched groups and search engines can increase weighting to present keywords in the URLs rank the more correlative results and provide for users.
