Dear colleagues! I present to you the SiteAnalyzer program, which is intended for technical analysis and site audit (server response codes, presence of "broken" links, links to external resources, check for availability of title, keywords, description, h1-h6 headers, check for duplicate pages, etc). This is a free analogue of the program Screaming Frog SEO Spider and similar to it. The analysis is performed by scanning all pages of the site (crawling the site by links), after which, based on parsed data, you can audit the parameters of interest. Key features Scanning of all pages of the site, as well as images, scripts and documents Obtaining server response codes for each page (200, 301, 302, 404, 500, 503, etc.) Determining the presence and content Title, Keywords, Description, H1-H6 Search and display the "duplicate" pages, meta tags and headers Determining whether an attribute rel="canonical" for each page of the site Following the directives of "robots.txt" file or meta tag "robots" Accounting rel="nofollow" when crawling pages on your site Reference analysis – finding internal and external links to pages (within the site) Determination of the number of referrals from the page (redirect) Determining the level of nesting pages relative to the main Generate sitemap "sitemap.xml" (with the possibility of splitting into several files) URL filtering by any parameter Export reports to CSV and Excel (full report in Excel-format) Differences from analogues Low demands on computer resources, low consumption of RAM To store data, a local database is used that is characterized by its performance and reliability Scanning websites of any volumes due to the low requirements of computer resources Portable format (works without installation on a PC or directly from removable media) I will be glad to any comments and wishes on the work and development of the program.
