I am doing SEO for 17 years now, both onsite and offsite, local GMB or regional and I am a certified SEO & Adwords as well. I have a vast experience that covers a full spectrum of SEO campaign. I optimize websites, e-commerce or not, on any platforms; from html tag optimization to meda data and keywords structure - all for permanent ranking of multiple and highly-searched volume keywords, traffic generation and organic conversions.
These are the procedures on how I do things in SEO:
SEO Comprehensive Audit:
Using my premium SeRanking and ahref organic/paid campaign tools, I uproot all the onsite errors to rectify on meta data, sending over a PDF technical errors to fix ( both for the developer and SEO ) robot txt, sitemaps, html tags, speed, canonical errors - all for dev's fixes. SEo stuff, toxic links to disavow, Google Console fixes, and all onsite fixes on site's admin or backend. Do manual schema markup, each page url, each item/product page, h1 or h2 on pages and blogs, alt image txt, geotags, html improvements, fixing broken links, 404 codes, internal and external links, configure and optimize Google analytics and tag manager, et al.
SEO Competitor's Analysis:
Analyze the top 5 organic or PPC competitors through ahref, what potential keywords are they ranking for and grab them, the keyword gaps, the low-hanging fruits and blog title to work on. Keyword Finder and aHref give me accurate search volumes per country, per region, per location - what factors these competitors are having an edge among others, the semantic keywords and the URLs competitor's backlinks and build from them.
Aside from those tools I mentioned, I also use a premium indexer ( Speedlinks ) tool to immediately index backlinks & pages and Article Forge for web2 / article directories backlinks purposes ) all white hat tools to help boost my manual SEO activities, ranking keywords be it local or global. I never use blackhat methodologies or any suspicious spamming techniques. With these tools , I can optimize multiple websites and launch organic keywords campaigns simultaneously.
Familiarity with competitors links or reverse engineering, building backlinks or doing offsite SEO after onsite has been done 80%. Advanced linkwheel, bookmarking, inbound and outbound links, relevant directories submission to high traffic, local listing, contextual linking, and guest posting when needed.
I can only work on a part-time or on a long term basis.
